Rice University scientists have discovered a novel phenomenon of light-induced lattice expansion in perovskite materials. The lattice expansion cures bulk and interface defects, which leads to an enhancement of perovskite optoelectronic properties. In a collaboration led by Rice University and Los Alamos National Laboratory found that to be the case with a perovskite compound touted as an efficient material to collect sunlight and convert it into energy. The press release likens the discovery as some materials are like people. Let them relax in the sun for a little while and they perform a lot better. Constant illumination was found to relax the lattice of a perovskite-like material, making it more efficient at collecting sunlight and converting it to energy. The stable material was tested for solar cell use by scientists at Rice University and Los Alamos National Laboratory. (Click to enlarge) The researchers led by Aditya Mohite, a staff […]
