Getting the lead out—New material for perovskite solar cells replaces lead with titanium

By Faye Oney / February 23, 2018

Researchers have created a material that replaces lead with titanium that could be used in inorganic thin-film perovskite solar cells. Their lead-free perovskite offers better stability and a more environmentally-friendly alternative for tandem solar cells.

Researchers flip a ‘chemical switch’ to improve perovskite’s thermal stability

By Stephanie Liverani / May 31, 2016

Researchers from Brown University—in collaboration with the National Renewable Energy Laboratory and the Chinese Academy of Sciences’ Qingdao Institute of Bioenergy and Bioprocess Technology—are getting closer to making perovskite solar cells a mass-market reality. It’s all in the “flip of a switch.”
