Nanocrystals enhance photovoltaics Researchers in the US have made a solar cell from two types of inorganic nanocrystal. Unlike hybrid devices that contain both nanocrystals and a semiconducting polymer, the cell was stable in air. The cell, which was made by Ilan Gur and co-workers at the Lawrence Berkeley National Laboratory and the University of California at Berkeley, had a power-conversion efficiency of nearly 3% (Science 310 462). The design is based on nanocrystals of cadmium selenide (CdSe) and cadmium telluride (CdTe).
