Some solar devices, like calculators, only need a small panel of solar cells to function. But supplying enough power to meet all our daily needs would require enormous solar panels. And solar-powered energy collected by panels made of silicon, a semiconductor material, is limited – contemporary panel technology can only convert approximately seven percent of optical solar waves into electric current. Profs. Koby Scheuer, Yael Hanin and Amir Boag of Tel Aviv University's Department of...

Researchers in Singapore have exploited advanced nanostructure technology to make a highly efficient and yet cheaper silicon solar cell. With this development, the researchers hope that the cost of solar energy can be halved. Developed jointly by Nanyang Technological University (NTU) and A*STAR Institute of Microelectronics (IME), the new thin-film silicon solar cells are designed to be made from cheaper, low grade silicon. However it is able to generate electricity currents close to that...

New MIT-developed materials make it possible to produce photovoltaic cells on paper or fabric, nearly as simply as printing a documentThe sheet of paper looks like any other document that might have just come spitting out of an office printer, with an array of colored rectangles printed over much of its surface. But then a researcher picks it up, clips a couple of wires to one end, and shines a light on the paper. Instantly an LCD clock display at the other end of the wires starts to display...

A scientific advance in renewable energy which promises a revolution in the ease and cost of using solar cells, has been announced today, Monday 4 July 2011. A new study shows that even when using very simple and inexpensive manufacturing methods - where flexible layers of material are deposited over large areas like cling-film - efficient solar cell structures can be made. The study, published in the Journal Advanced Energy Materials, paves the way for new solar cell manufacturing techniques...
