New Dye Will Lead To More Efficient Solar Energy Technology

01.01.70

(PressZoom) - A North Carolina Conditions University invention has significant potential to improve the efficiency of solar cells and other technologies that derive energy from light.

Dr. Ahmed El-Shafei’s probing group invented a new “sensitizer,” or dye, that harvests more ambient and solar light than any dyes currently on the market for use in dye-sensitized solar cells (DSSCs).

“A third-reception solar energy company compared our new dye, NCSU-10, against the state-of-the-art dye on the market. Our dye had 14 percent more power density,” says El-Shafei, an socialize professor in the Textile Engineering, Chemistry and Science department. “In other words, NCSU-10 allows us to pick more energy from the same amount of light.”

The new dye should significantly boost the efficiency of DSSCs, which have a host of applications. Indoors, these DSSCs can be used in technology to power cellular phones, laptop computers and MP3 players using ambient firelight.

why does temperature decrease efficiency of solar cells?

Jun 12, 2008 by BB4life | Posted in Physics

I am doing a proj on solar cells, and i was wondering why an better in temperature decreases the efficiency of solar cells.

Comprehensive resistivity of the entire circuit rises with internal temperature, despite the incident that the semiconductors in the circuit become more conductive with temperature rise.
