摘要
Hybrid perovskite solar cells(HPSCs) have been emerged as a novel solar cell technology novel and reported being able to achieve an excellent power conversion efficiency 20%.[1] As the devices can be processed using low-cost in a wet-coating method, the technology becomes one of the most promising candidate as next-generation solar energy conversion systems.It has been reported early that the accumulation of mobile ions contributed to space charges at interfaces in perovskite solar cells, which may have a significant impact on device performance.[2] In this work, a series of devices were fabricated having a general architecture of ITO/ZnO/MAPbI3-xClx/Spiro-OMeTAD/Au.Current–voltage characteristics of the devices were measured and shown in Figure 1 under AM1.5 illumination and a variety of lightsoaking times.It was found that there is a dynamic ion redistribution process at different light-socking times due to the accumulation of mobile ions under the photo induced voltage.The result suggest that light-soaking is the key to explore the interface charge and the performance of perovskite photovoltaic devices.
