外文摘要：Compared with the power conversion efficicency,the operational stability of perovskite solar cells(PSCs)remains a major challenge hampering its commercialization.However,conducting a light soaking test under 1 sun illumination to get a long lifetime is time-consuming and experimentally inefficient.Here,we report an accelerated stability test protocol by aging PSCs under high-intensity light illumination to accelerate the evaluation of their operation stability.It is found that the efficiency degradation rate of a typical inverted PSC is almost linearly dependent on the light intensity within the range of 1 to 4 suns regardless of the encapsulations.The results prove that it can save the light-soaking time by at least 4 times to predict the operation lifetime on the basis of the equivalent light irradiation dose.
