有机金属三卤化物钙钛矿（OTP）器件的连续照射可以引起光伏极化效应，称为光诱导自极化（LISP），这显著提高了稳定的器件效率。LISP的效果与通过外部施加的电场进行的极化相当，这可以通过由光电压诱导的附加电场驱动的OTP层内的离子/空位的重新分布来解释。
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.
