Abstract

With increasing interest in investigating the stability of perovskite single-junction and perovskite/silicon tandem cells in outdoor environments, photoluminescence (PL) imaging, a valuable technique to analyze solar cell quality, could greatly benefit studies regarding the performance of these technologies in the field. This study presents outdoor PL images of perovskite-based solar cells, utilizing sunlight as the sole excitation source. Furthermore, it establishes the first proof of concept for quantitative outdoor implied open-circuit voltage (

i V_{OC}

) imaging. By introducing these novel methods, which rely on inexpensive equipment, this study paves the way for PL and

i V_{OC}

imaging to become a widely adopted and insightful characterization tool for monitoring the field performance and stability of perovskite-based solar cells.

利用阳光激发的钙钛矿太阳能电池的室外隐含开路电压成像

随着人们对钙钛矿单结和钙钛矿/硅串联电池在室外环境下稳定性的研究日益增加，光致发光（PL）成像技术作为一种分析太阳能电池质量的有价值的技术，可以极大地促进这些技术在该领域的性能研究。本研究展示了钙钛矿基太阳能电池的室外PL图像，利用阳光作为唯一的激发源。此外，它建立了定量室外隐含开路电压（iVOC）成像的第一个概念证明。通过引入这些依赖于廉价设备的新方法，本研究为PL和iVOC成像铺平了道路，使其成为一种广泛采用的有见地的表征工具，用于监测钙钛矿基太阳能电池的现场性能和稳定性。
