Recent review on electron transport layers in perovskite solar cells

摘要

Organic-inorganic perovskite solar cells demonstrate immense potential for future photovoltaic application due to their remarkable efficiency advancements competitively low-cost. To unlock the full capability of perovskite, developments to the neighbouring layers play immense roles in the ultimate performance of a perovskite solar device. Here, a brief review comprising of the advancements and roles of electron transport layers (ETLs) is discussed. In addition, the effects of ETL on the charge transport, hysteresis, and stability of perovskite solar devices, along with high-performing examples, are also explored.
