Abstract

Mesoscopic carbon-based lead halide perovskite solar cells (CPSCs) represent a promising architecture for commercialization in the field of perovskite photovoltaics as they are stable, potentially low cost, and use easily scaled production methods. However, the use of toxic and psychoactive solvents...
