摘要

Hybrid organic/inorganic perovskite solar cells have emerged as among the most competitive photovoltaic technologies of the future thanks to their superb and rapidly improving power conversion efficiencies(PCEs).For realistic deployment of the perovskite photovoltaic technology in large scale, however, device stability has become more and more important issue of the day.This talk will present our recent results on(1) the relationship between device stability and ion movement of the perovskite layer; 2) the use of NiO and carbon nanostructures for efficient hole extraction and enhanced device stability; and 3) the development of perovskite and interface engineering techniques for improving both efficiency and stability.Implications of these results on the future development of perovskite solar cells will be discussed.
