The efficiency of a solar cell is intimately related to the fate of photogenerated electron–hole pairs in the absorber layer. The interaction and capture of charge carriers through defects acting as recombination centres may significantly limit the solar cell’s open-circuit voltage and thus depress its overall performance. The efficient charge generation and collection in devices based on lead-halide perovskites are, to a first approximation, related to the extremely long lifetimes of photogenerated carriers.

Abstract
The efficiency of a solar cell is intimately related to the fate of photogenerated electron–hole pairs in the absorber layer. The interaction and capture of charge carriers through defects acting as recombination centres may significantly limit the solar cell’s open-circuit voltage and thus depress its overall performance. The efficient charge generation and collection in devices based on lead-halide perovskites are, to a first approximation, related to the extremely long lifetimes of photogenerated carriers.File in questo prodotto:
