New solar cells are more efficient
The devices harvest blue as well as red light to reap more energy than ever before.
The new hybrid cell absorbs red as well as blue light to boost the electrical current. A typical solar cell generates a single electron for each photon captured. But by adding the organic semiconductor pentacene, the solar cells can generate two electrons for every photon from the blue light spectrum. This could enable the cells to capture 44 percent of the incoming solar energy. Full Story »
