高效钙钛矿太阳电池是近年来光伏界的主要研究热点之一,得益于其原材料价格低廉,制程工艺较晶硅技术简单,制造能耗较低,有望成为未来光伏行业的替代性发电技术。然而钙钛矿太阳电池关键电参数的准确测量也是近年来的行业难题之一,主要表现在传统的电流-电压特性曲线测量方法不能充分客观反映钙钛矿太阳电池的发电性能,以及缺乏针对其稳定性的测量和评估方法。文中研究和提出一套针对高效钙钛矿太阳电池测量和评价方法,并根据对三种常见尺寸的钙钛矿太阳电池的电性能测量结果,分析了钙钛矿太阳电池的迟滞效应和稳态光照下的功率衰减情况,为光伏行业评估高效钙钛矿太阳电池电性能提供了具有一定实操性的技术依据。

High performance perovskite solar cells have been one of the main research focuses in the photovoltaic industry in recent years.Thanks to their low cost of raw materials,simpler manufacturing process compare to silicon technology,and lower manufacturing energy consumption,it is expected to become an alternative power generation technology in the future.However,the accurate measurement of the key electrical parameters of perovskite solar cells is also one of the challenges in the industry,mainly because the traditional measurement method of current-voltage characteristic curve can not reflect the power generation performance of perovskite solar cells completely and objectively.Additionally,Measurement and evaluation methods for theirs stability is another difficulty.This paper studies and proposes measurement and evaluation methods for high-performance perovskite solar cells.Based on the electrical performance measurement results of three common sizes of perovskite solar cells,the hysteresis effect of perovskite solar cells and the power attenuation under steady state lighting are analyzed,which provides a practical technical reference for the industry to evaluate the electrical performance of high performance perovskite solar cells.
