tum-spray-on-coating-organic-sensor-1Analogous to way old camera films recorded light exposition onto photographic film, image sensors in digital camera convert the light from the lens to our digital photos. Researchers at the Technische Universit√§t M√ľnchen (TUM) have developed image sensors that consist of electrically conductive plastics which are more sensitive to light compared to their conventional silicon… »

Using luminescence to break the solar cell efficiency record

By Damir Beciri
One Comment26 April 2012

yablonovitch-solar-cell-1Researchers from the University of California, Berkeley, came across a relatively simple solution based on a mathematical connection between absorption and emission of light that could lead to improvement of flat-plate solar cell efficiency. Although their concept is counterintuitive, the researchers managed to demonstrate that solar cells which are able to emit light more efficiently… »
