摘要Abstract:
Recently, perovskite-based solar cells (PSCs) have attracted worldwide interest with a certified 22.7% efficiency in a few years’ time. However, long-term stability is still the key issue for its future development. Aiming at this point, some works have been carried out in our lab. Materials processing and interface engineering have been deployed to improve the intrinsic long-term stability of perovskite absorber.[1-7] Optimized device structures have also been developed to improve the device stability, such as the applications of new-type charge transporting materials and carbon counter electrodes.[8-13] Furthermore, stability-related theoretical studies have been carried out. An electrically modulated transient photocurrent/photovoltage technology has been developed and used to investigate the slow charge and electric field response inside PSCs. The intrinsic hysteresis behaviour, photocharge accumulation and recombination in PSCs have been systematically investigated. [14-20]
