Breakthrough in solar cell material characterization

Graduate student Yaochuan (Josh) Mei and Prof Oana Jurchescu, together with their collaborators from University of Utah have developed the first transistor based on hybrid organic-inorganic perovskites, which are the electronic materials in the fastest advancing solar technology to date.

Necessary prerequisites for a material that forms an efficient solar cell are strong optical absorption and efficient charge carrier transport. With these first generation transistors, the electrical properties were directly measured for the first time, eliminating indirect approximations.
