New Efficiency Benchmark For Dye-sensitized Solar Cells

Scientists have achieved a record light conversion efficiency of 8.2% in solvent-free dye-sensitized solar cells. This breakthrough in efficiency without the use of volatile organic solvents will make it possible to pursue large scale, outdoor practical application of lightweight, inexpensive, flexible dye-sensitized solar films that are stable over long periods of light and heat exposure.

High-Efficiency, Flexible, High-Stability Solar Cells

Nanotechnology-based hybrid nanocrystal inorganic thinfilm photovoltaics combine the best features of solar cells constructed from bulk thin-film silicon and from polymer solar cells. The colloidal nanocrystal (NC) cell technology offered here allows the production of air-stable solar cells processed using solution phase methods. The technology simplifies fabrication under ambient conditions, thus expanding the range of flexible or conformal substrates that can be used.

Researchers Improve Solar Cell Performance

Vegematic writes "Researchers at MIT have improved solar collectors using dyes. They just increased their performance results by a factor of 4. These paint-on materials can increase the power obtained from existing solar cells by a factor of over 40 without needing to track the sun. 'By collecting light over their full surface and concentrating it at their edges, these devices reduce the required area of solar cells and consequently, the cost of solar power. Stacking multiple concentrators allows the optimization of solar cells at each wavelength, increasing the overall power output.' There is also a shorter FAQ available."

Prototype power plant shatters solar record

On a perfect New Mexico winter day—with the sky almost 10% brighter than usual—Sandia National Laboratories and Stirling Energy Systems (SES) set a new solar-to-grid system conversion efficiency record by achieving a 31.25% net efficiency rate. The old 1984 record of 29.4% was toppled Jan. 31 on SES’s “Serial #3” solar dish Stirling system at Sandia’s National Solar Thermal Test Facility.

Nanowires make bendy solar cells

Highly bendable "dye-sensitized" solar cells made from zinc oxide nanowire photoelectrodes on plastic substrates have been developed by researchers in Singapore. The devices, which conserve their photovoltaic properties even when greatly bent, could find use in a variety of flexible and portable applications, such as solar-cell mobile phone chargers, clothes and umbrellas.

Promising New Method To Fabricate Ultra-thin Silicon Solar Cells Developed

IMEC is developing a new method to produce ~50µm thin crystalline silicon wafers for use in solar cells. The process involves mechanically initiating and propagating a crack parallel to the surface of a Si wafer. In this way, Si foils with an area of 25cm˛ and a thickness of 30-50µm have already been produced. The method makes use of industrially available tools (screen printer, belt furnace) and is potentially kerf-loss free.

Solar Cells - Made In a Pizza Oven

stylemessiah writes "The winner of several Eureka Science Awards in Australia is a crafty chick who devised a way to create solar cells cheaply using a pizza oven, nail polish and an inkjet printer. This was developed to address the high cost of cells and in particular for the world's poorest regions. She wanted to give the ~2 billion people around the world who don't have electricity the gift of light and cheap energy. This could have profound (and a good profound) implications for education and health in those in the poorest regions in the world. And it all started with her parents giving her a solar energy kit when she was 10 ..."
