With the realization of highly efficient perovskite solar cells, the long-term stability of these devices is the key challenge hindering their commercialization. In this work, we study the temperature-dependent stability of perovskite solar cells and develop a model capable of predicting the lifetime and energy yield of perovskite solar cells outdoors. This model results from the measurement of the kinetics governing the degradation of perovskite solar cells at elevated temperatures. The individual analysis of all key current-voltage parameters enables the prediction of device performance under thermal stress with high precision. An extrapolation of the device lifetime at various European locations based on historical weather data illustrates the relation between the laboratory data and real-world applications. Finally, the understanding of the degradation mechanisms affecting perovskite solar cells allows the definition and implementation of strategies to enhance the thermal stability of perovskite solar cells.
随着高效钙钛矿太阳能电池的实现，这些器件的长期稳定性是阻碍其商业化的关键挑战。在这项工作中，我们研究了钙钛矿太阳能电池的温度依赖性稳定性，并开发了一个能够预测钙钛矿太阳能电池在户外的寿命和能量产量的模型。该模型源于对高温下钙钛矿太阳能电池降解动力学的测量。对所有关键电流-电压参数的单独分析能够高精度地预测热应力下的器件性能。基于历史天气数据对欧洲不同地点器件寿命的外推说明了实验室数据与实际应用之间的关系。最后，对影响钙钛矿太阳能电池的降解机制的理解有助于定义和实施提高钙钛矿太阳能电池热稳定性的策略。
