摘要：

Continuous illumination of the organometal trihalide perovskite (OTP) devices can cause the photovoltaic poling effect, termed light-induced self-poling (LISP), which improves the stabilized device efficiency significantly. The effect of LISP is comparable to the poling by an externally applied electric field, which can be explained by the redistribution of ions/vacancies within the OTP layers driven by a photovoltage-induced additional electric field. © 2015 WILEY-VCH Verlag GmbH & Co.
