Resurrection of the Cuprous Sulfide Solar Cell via a Novel Device Architecture and Acceptor Compensation
Hybrid perovskite (HP) based solar cells have increased in efficiency faster than any other technology in the history of solar cells. The best HPs contain 6 elements (C, H, N, Pb, I, and Cl). The space of possible composition variations and substitutions is extraordinarily large, and it would be an incredibly arduous task if one was required to make a full solar cell in order to test a different composition. In our exploratory work, we are employing combinatorial methods and a unique photoluminescence tool developed by our group in order to effectively explore HP ink compositions and probe their optoelectronic quality. We have already observed systematic changes in key optoelectronic properties such as the quasi-Fermi level splitting with respect to material composition. We are now poised to rapidly discover superior HP ink formulations for applications in both tandem and single junction solar cells.
