University of Cambridge Solar cells offer the opportunity to harvest abundant, renewable energy. Although the highest energy light occurs in the ultraviolet and visible spectrum, most solar energy is in the infrared. There is a trade-off in harvesting this light, so that solar cells are efficient in the infrared but waste much of the energy available from the more energetic photons in the visible part of the spectrum. When a photon is absorbed it creates a single electronic excitation...

By Xu, Zhihua Zang, Huidong; Hu, Bin Organic semiconducting materials have demonstrated attractive light-absorption and photocurrent-generation functions due to their delocalized pi electrons as well as intra-molecular and inter- molecular charge separation processes. On the other hand, organic semiconducting materials have easy property tuning, are mechanically flexible, and have large-area thin film formation properties. As a result, organic materials have become potential candidates in...
