Perovskite solar cells temperature dependence under space-like conditions — •Anthony Vizcaino, Simon Alexander Wegener, and Peter Müller-Buschbaum — TUM School of Natural Sciences, Chair of Functional Materials, 85748 Garching, Germany

In recent years, perovskites have attracted the scientific community's attention due to their properties and possible applications, making their use in solar cells one of the most relevant. Their high-power conversion efficiency, power-to-weight ratio, and manufacturing compared to the to-date used multi-junction devices make them a promising device for space applications, where it is possible to take advantage of all the intensity of sunlight that at the Earth*s surface is lost by absorption or scattering by the atmosphere. However, in this scenario, radiation and high temperatures would affect the solar cell. This study focuses on one of these problems and tries to understand how extreme temperatures and thermocycling through large periods of heating and cooling encountered in low Earth*s orbit affect perovskite solar cell performance and degradation. Operando studies allow to simulate thermal cycling conditions and measure the transmittance of solar cells, which combined with electrical characteristics from I-V measurements and active layer morphology from GIWAXS give us a robust knowledge of the temperature dependence of perovskite-based solar cells.
