Monolithic bifacial perovskite-CdSeTe tandem thin film solar cells for harvesting light from the environment

Project #D2021-04Invention DescriptionThe University of Toledo has developed a new tandem solar cell design — the bifacial tandem (Fig. 1) that enabled the first realization of a working monolithic tandem solar cell comprising wide-bandgap metal halide perovskite and narrow-bandgap cadmium selenide telluride (CdSeTe, or CST). The bifacial strategy...

Additive for improved stability of perovskites against water

Project ID: D2019-50 Background Perovskites are commonly used in photovoltaics, LEDs, and water splitting devices. Despite success in increasing cell efficiencies using perovskites, their instability against moisture limits their practical application. Incorporating hydrophobic materials into the perovskite has been used to mitigate this problem,...
