摘要：
In this study，the influence of introducing MoO3 hole modification layer between hole transport layer Spiro-OMeTAD and Ag electrode on the photovoltaic performance of the blade- coated perovskite solar cell device was investigated. The mechanism was examined through a series of tests encompassing electrical conductivity measurement，steady-state photoluminescence spectra，contact angle with water，etc. The results of experiments and tests indicate that MoO3 can effectively improve hole transport capability and reduce interfacial resistance while protecting the underlying Spiro-OMeTAD and perovskite layers from water and oxygen degradation in the air. Based on MoO3 interface modification layers，the blade-coated perovskite solar cell device’s photovoltaic conversion efficiency increases from 15.14% to 18.30%，especially the average fill factor rises from 60% to 76%. At the same time，the stability of devices is also improved，with the unpackaged device still maintaining 90% of it initial efficiency after 400 hours. © 2024 Science Press. All rights reserved.
