钙钛矿太阳能电池（PSCs）以其高效、低成本的特点得到了世界范围内的广泛关注。然而，对psc进行可靠的测量是具有挑战性的，这给研究人员比较和复制已发表的结果带来了很大的困难。本文总结了影响PSCs评价的主要测量方法和关键因素，如电流-电压测量中的滞后，为减少光谱和光强不匹配而对太阳模拟器进行校准，以及计算电流密度和功率转换效率的区域。在相同的测量方法下，还将PSCs与具有不同反馈的n-i-p或p-i-n结构进行了比较。最后，给出了一种测量方案，以帮助研究人员获得接近公共测试中心认证的可靠测量结果。
Perovskite solar cells (PSCs) have undergone an incredibly fast development and attracted intense attention worldwide owing to their high efficiency and low‐cost fabrication. However, it is challenging to make a reliable measurement of PSCs, which creates great difficulty for researchers to compare and reproduce published results. Herein, the major measurement methods and key factors affecting evaluation of PSCs are summarized, such as hysteresis in current–voltage measurement, calibration of solar simulators for less mismatch in spectra and light intensity, and the area for the calculation of current density and power conversion efficiency. PSCs are also compared with n–i–p or p–i–n structures that exhibit different feedback under the same measurement methods. Finally, a measurement proposal is provided to help researchers obtain reliable measurement results close to those certified by public test centers.
