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...

Inexpensive, Earth-Abundant, and Tunable Hole Transport Material for CdTe Solar Cells

Project ID: D2017-08Background Photovoltaic (PV) cells have been produced with a wide variety of materials for each functional layer. The typical PV is a substrate layer coated with a semiconductor layer and two ohmic contacts. Thin film solar cells use a thin absorbing layer, such as Cadmium telluride (CdTe). CdTe is the most eco-friendly, high efficiency,...
