Ultrafast measurements explain quantum dot voltage drop
Los Alamos NM (SPX) Mar 23, 2017
Solar cells and photodetectors could soon be made from new types of materials based on semiconductor quantum dots, thanks to new insights based on ultrafast measurements capturing real-time photoconversion processes. "Our latest ultrafast electro-optical spectroscopy studies provide unprecedented insights into the photophysics of quantum dots," said lead researcher Victor Klimov, a physicist specializing in semiconductor nanocrystals at Los Alamos National Laboratory, "and this new information hel ... read more
