There was developed a way to mount tiny silicon crystals for solar panels.
The complexity in this case is such that in large systems the force of gravity makes it easy to mount the items as necessary, but on a microscopic scale, when the linear dimensions of each element is thinner than a human hair, it’s not so easy. There begin to interfere outside forces, such as magnetic and electrostatic. For such dimensions, elements, that begins to play a greater role than gravity.
To overcome the difficulties, there was designed a flexible substrate a thin layer of copper coated polypropylene terephthalate (PET). On the substrate through the same distance there is engraved area, the size of which coincides with the size of silicon crystals. Ready-made substrate was lowered into a bath of molten solder, which covered the exposed area of copper foil. Each silicon crystal is of a cube with sides of 20-60 microns, one of which was gilded. On the silicon side suffered a hydrophobic coating (water repellent), whereas at a gilt side – hydrophilic (water attracting).
When the cells were placed in a container containing oil and water, they are neatly placed at the interface between two liquids. Gilded side is facing the water boundary that is down. The substrate is slowly moved across the border between the media as a conveyor belt, and the elements neatly stuck to the gold-coated side solder coatings. Accuracy of the crystals was 98%. Installation was covered with epoxy resin to fix the elements on the ground.
Such device can install more than 20 000 crystals in a minute. Furthermore, elimination of dependence on the strength of gravity allowed to reduce the size of silicon crystals. Previously it could not be less than 100 microns.
A key feature of the experiment was to reduce the time to build to avoid oxidation of the crystals, which could decrease the surface energy and money assembling decline. Used in the device, the water should be acidic pH 2.0, and the temperature was supposed to be equal to 95C, to protect the solder from oxidation.
Thus obtained assembly can be used in numerous applications such as solar panels, video screens and tiny semiconductors.
Use this method for the manufacture of cells of solar panels would significantly reduce the cost by increasing the speed and reduce the amount of required silicon crystals what is extremely important.
Besides that there is known that new solar panel using silver nanoparticles, much easier and cheaper analogues used today in industrial scale. In addition, batteries with silver nanoparticles can be flexible.
Scientists say they have experimented with a variety of polymeric semiconductors to absorb solar energy and produce electricity. During the work, they found that the addition of the panels of silver, greatly increases productivity. Silver particles should be placed directly on a plastic substrate, and it will enhance the development of batteries.

In research laboratories there were created new solar cell modules, main layer of which absorb most of the world to be converted into electric current, which is composed entirely of compounds of common and readily available chemical elements
The energy that can be derived from solar radiation coming to Earth for an hour, is higher than the energy that the planet consumes in a year, but the contribution of solar energy in a worldwide system of electricity supply is currently less than 0.1%, primarily due to high cost. Finding ways to create technology solar panels, which cost per watt is comparable with traditional electricity generation, and which has the potential to “terawatt” level, has become the main focus of research that brought to the final successful resolution of problems.
Developed by researchers solar cell also differs from its predecessors so that it was created using a combination of solutions and approaches based on nanoparticles – in contrast to the popular but expensive vacuum method. Technological changes will allow to significantly reduce manufacturing costs, as these changes are consistent with best practices in applying light-absorbing layers – such as printing, coating, applied by dipping (immersion) and by spraying, casting the film – which are characterized by high productivity and high utilization of materials.
Current thin-film solar cell panels, based on compound semiconductors, are demonstrating the efficiency at the level of 9-11%. These elements are most often used two costly chemical compounds – copper indium selenide, gallium and cadmium telluride. As a result of attempts to create cheaper solar panels on the basis of compounds, including widely distributed on earth chemical elements and not containing indium, gallium or cadmium are not able to surpass the barrier efficiency of 6,7% – in comparison with the new, record-breaking performance in 9 6%.
Researchers have developed a flexible solar cells that absorb up to 96% of incident light. This strong result was achieved due to special design elements: a plastic substrate are vertically oriented silicon pins. The developers are very low cost of materials used, as an element of 98% consists of plastic, while the share of expensive materials is 50 times less than for traditional batteries.
Experimental samples of the proposed solutions demonstrate up to 90% efficiency, whereas the figure for the best samples of silicon cells is only 25%. Silicon pins or hair thickness of 1 micron and a length of 30 to 100 microns are covered with transparent plastic. Part of the luminous flux is not absorbed by the rod, is reflected from the substrate and reaches the other rods, thereby increasing the absorption coefficient. Currently, researchers are working to raise tension and increase the size of a new element to produce whole rolls of solar panels.

Solar power plant is an engineering construction, which serves converting solar radiation into electrical energy. Methods for conversion of solar radiation are different and depend on the design of power plants.
SES design
These plants are based on the principle of getting the water vapor from solar radiation. In the center of the station there is a tower height from 18 to 24 meters high (depending on power and some other parameters may be higher or lower), on top of which is a water tank. This reservoir is covered in black to absorb heat radiation. Also in this tower is pumping group that delivers steam to a turbine generator, which is located outside the tower. Circling the tower at a distance are heliostat. Heliostat – a mirror area of several square meters, fixed on a support and connected to a common system of positioning. That is, depending on the position of the sun, the mirror will change their direction. The main and most difficult task to direct all mirrors at the positioning station, so that at any time all the reflected rays from them got on the tank. In bright sunny weather the temperature in the tank can reach 700 degrees. These temperature parameters are used in most conventional thermal power plants, so the energy use standard turbines. In fact, the stations of this type can be obtained relatively high efficiency (20%) and high power.
SPP of plate type
This type of SPP uses the principle of generating electricity, similar to those of the tower SPP, but there are differences in the construction of the station. The station consists of separate modules. The module consists of the pillars on which is mounted truss design of the receiver and the reflector. Receiver located at some distance from the reflector, and it concentrates the reflected rays of the sun. The reflector consists of a mirror in the form of plates (hence the name), radially arranged on the farm. The diameters of these mirrors are about 2 meters, and the number of mirrors – a few dozen (depending on the power module). Such stations may consist of a single module (autonomous), and a few dozen (work in parallel with the network).
SPP, which are using photoelectricity
SPP of this type are now very common, because in general, SPP consists of a large number of individual modules (photoelectric) of different power and output parameters. SPP data are widely used to supply power to both small and large objects (private cottages, resorts, motels, industrial buildings, etc.). Photocell can be set almost anywhere, from the roof and facade of the building and ending with specially designated areas. The installed capacity also varies in a wide range, ranging from the provision of separate pumps, ending by power supply of a small village.
Combined SPP
Often, different types of SPP further establish heat exchangers to generate hot water, which is used for technical purposes, and for hot water and heating. This is the essence of the combined SPP. Also in the same area can be a parallel installation of concentrators and the photocell, which is also considered a combined SPP.

Solar energy is the direct use of sunlight to generate energy in any form. Solar Energy: Renewable energy is clean, that is not generating hazardous waste. Solar panel – one of the generators of alternative energy, which is transforming the solar electromagnetic radiation (in other words – the light) into electricity. It is the object of study solar energy. Manufacture of solar cells is growing rapidly in many different directions.
Types
Photovoltaic Converters – Semiconductor device directly convert solar energy into electricity (solar cells). Several joint FE called a solar cell.
Helios power plants (GEES). The solar plant using highly concentrated solar radiation as the energy to actuate the thermal and other machines (steam, gas turbine, thermoelectric and others).
Solar collectors (SC) are presented by low-temperature solar heating installation.
Organic battery – a device that converts sunlight into electricity by using genetically modified cells printed on thin plastic.
Solar and wind power plant
Solar panels are widely used in tropical and subtropical regions with a large number of sunny days. In the future they are likely to be used for recharging of electric vehicles. Solar collectors are used primarily for the needs of hot water and sometimes in support of heating systems.
Structure features photovoltaic panels cause a decrease in performance with increasing temperature.
Partial shading of the panel causes the output voltage drop due to losses in the dark element, which begins to act as a parasitic load. From this deficiency can be eliminated by installing a bypass on each cell panel.
From the performance of photovoltaic panels can be seen that to achieve maximum efficiency requires the correct selection of the load resistance. To do this, photovoltaic panels do not connect directly to the load, and use the controller photovoltaic systems, ensuring the optimum operation of the panels.
Ways to generate electricity and heat from solar radiation
Getting electricity by photovoltaic cells.
Converting solar energy into electricity using heat engines:
steam engines (piston or turbine), using water vapor, carbon dioxide, propane, butane, freon;
Stirling engine, etc.
Solar Energy – Heating the surface, absorbing the sun’s rays and the subsequent distribution and use of heat (concentrating solar radiation on the vessel with water for subsequent use in heating hot water or steam into electrical generators).
Solar balloon power (generation of water vapor inside the container balloon by heating the surface by solar radiation balloon coated with a selectively-absorbing coating). Advantage – the stock steam in the cylinder is sufficient for power at night and in inclement weather.
Advantages of solar energy
Accessibility and inexhaustible source.
Theoretically, the complete security to the environment, although it is likely that the widespread introduction of solar energy can change the look of the earth’s surface and lead to climate change (but at the present level of energy consumption it is extremely unlikely).

As alternative energy sources gain more popularity, companies expand their applications. Self contained solar panels lights are now being used on docks. Using The Sun To Run Dock Lights When boating, safety is the most important thing to consider. This is especially true at night, when just the simple act of docking your boat can be tricky. You definitely need to light your way to your dock, whether you’re got a big boat or a small one. A great way to show your way in are solar dock lights. Many dock lights rely on batteries or electricity to power them. Both options are fine, however, batteries can be annoying to constantly replace and purchase. Electricity might be a better choice, but you will need to pay that high electric bill, as well as contend with cords and other dangerous items. Solar dock lights are superior to other choices, as they are safer and cheaper to operate. Solar dock lights collect solar energy during the day. They accomplish this by using small solar panels that are usually positioned on top of the dock light.

The energy is then used to recharge a battery located inside the dock light (most of the time the battery is a standard NiCad rechargeable battery). The recharged battery then powers a LED light. These small lights are very bright, but take only a minimal amount of energy to run. Therefore, the energy collected during the daylight hours is enough to power the dock light through many hours at night. Some of the dock lights are able to automatically turn on when the sun goes down, which makes the safety of the lights even greater. Some solar dock lights even come with the ability to change the color of the LED inside the lamp. This can be very helpful, as you can use different colors such as red and green to mark the left and right of your dock. You can also buy several of the dock lights in order to line a path down your dock in bright white light. These dock lights are also made to fit all standard docks and posts, so you can be sure that they will fit on your own dock. Solar dock lights are an excellent choice for lighting your boating path. Because safety is the key to boating fun, knowing that these lights will be there waiting for you when sunset hits is a great comfort. Knowing that these dock lights are inexpensive to purchase and run can also add to your enjoyment of boating at night.

Get energy for eight to nine cents per kilowatt hour

Bloom Energy has launched a new energy server with patented solid-oxide fuel-cell technology that can generate 100 kW, enough to power one small office building or 100 average U.S. homes. Rather than purchasing it from a utility company, the Bloom Energy Server makes it possible to generate electricity locally.

The company says a server costs from $700,000 to $800,000, not including fuel, and that it will generate electricity for eight to nine cents per kilowatt hour. Proponents hope that the servers will someday provide clean, reliable, and affordable energy around the world. To date, A-list customers include Google, eBay, Wal-Mart, FedEx, Coca-Cola, Cox Enterprises and Wal-Mart.

It is not for everyone . . . yet

In a NewsFactor.com article, Bloom Energy CEO Dr KR Sridhar said the company is “dedicated to making clean, reliable energy affordable for everyone in the world.” At this time, however, it would take a lot more than a payday loan, even multiple numbers of payday loans, to get a Bloom Energy Server. The much-hyped launch of the energy server probably was not attended by many everyday people in need of a cash advance, but high-profile types like California Governor Arnold Schwarzenegger, former Secretary of State Colin Powell, and venture capitalist John Doerr were there.

100 percent cleaner than traditional methods

According to the NewsFactor.com article, rather than the traditional combustion method, the Bloom Energy Server contains thousands of ceramic fuel cells that generate electricity using an electrochemical process. The electrical generation process is 100 percent cleaner than traditional coal-fired electrical generation when the Bloom Energy Server cells are powered by biogas or some other renewable fuel source. The Bloom Energy Server is about 67 percent cleaner than traditional methods when powered with fossil fuels.
