PIN-type perovskite solar cells for space applications — •Ruodong Yang, Simon A. Wegener, and Peter Müller-Buschbaum — TUM School of Natural Sciences, Chair for Functional Materials, 85748 Garching, Germany

Perovskite solar cells have advantages such as low costs and high power-to-weight ratio, which render them to be promising candidates for space applications, where the mass is crucial for launch costs. In this study PIN-type solar cells are investigated. With its inverted p- and n-type structure, it has great research potential. However, solar cells in space also face challenges, such as vacuum, extreme temperature fluctuations during each orbit, and high radiation levels. The purpose of this study is to optimize the manufacturing procedure of PIN-type perovskite solar cells to address these challenges. We investigate the power conversion efficiency of the solar cells under similar environmental conditions to the low Earth orbit with illumination from an AM0 light source and thermal cycling by using optical microscopy to observe the structural changes during the operation. With the results of the measurements, the manufacturing procedure will be optimized, to determine the key factors to improve the performance and efficiency of PIN-type cells under space conditions.
