摘要
ABSTRACT This paper presents an outdoor performance monitoring method for degradation studies of perovskite modules, focusing on a large‐area perovskite module (81.9 cm 2 ) over a long‐term monitoring campaign. The module underwent an industrial lamination process to prevent long‐term degradation from environmental factors. The characterization procedure involved degradation correction and determining the temperature coefficients and electrical parameters of the module using initial days of measurements. The results demonstrated temperature coefficients for I sc , V oc , and P m ( α ′, β ′, and γ ) of −0.071%·K −1 , −0.119%·K −1 , and −0.113%·K −1 , respectively, indicating a minimal temperature influence on this technology compared with conventional ones. Using this coefficient, the STC electrical parameters were retrieved from 1‐min power output data, resolving the uncertainty of the indoor/outdoor IV curve measurements caused by the curve scan direction (JV hysteresis effect). We also highlight the initial remarkable capacity recovery effect of almost 16% during the first 2 days of operation. Additionally, a procedure that includes the IV curves analysis taken every 10 min and their translation to standard conditions has been implemented to evaluate the degradation of the module over the long‐term outdoor campaign. The results show three different trends over the period.
