The dye regeneration mechanism involving the organic triphenylamine (TPA) dyes and cobalt-based redox mediator, [Co(bpy)3]2+/3+, were investigated using density functional theory (DFT) combined with t
Methylammonium lead halide perovskites are promising absorbers for solution-processed thin film photovoltaics owning to the unique combination of good optical absorption characteristics and long charg
