This article discusses some suggestions to improve carrier transfer and reduce recombination loss for highly efficient perovskite solar cells, including primary requests on charge carrier transfer dynamics, reasonable design methodologies, and tuning interface interaction between perovskite and charge transport layers.
The power conversion efficiency of thin film solar cells using organic-inorganic hybrid lead halide perovskite as an absorber has achieved over 25%. An augment of the output voltage can further increase the efficiency approaching the Shockley-Queisser efficiency limitation, which is highly correlated with charge carrier management at interfaces in perovskite devices. This perspective presents some considerations to improve carrier transfer and reduce recombination loss for highly efficient perovskite solar cells, including primary requests on charge carrier transfer dynamics, reasonable design methodologies of interfacial materials, and tuning interface interaction between perovskite and charge transport layers.
