Abstract

<jats:p>Perovskite based photovoltaics are attractive for applications in space. The space environment is harsh with ionizing radiation, atomic oxygen, ultra‐violet radiation, extreme temperatures and thermal cycling. Here we analyze the thermal performance of perovskite active layer and perovskite photovoltaic devices in low earth orbit. We determine a 1 <jats:italic>μ</jats:italic>m silicon oxide layer coupled with 500 nm zirconia thin film aid in cell thermal management. We model the residual stresses between various layers in a device and prove that thermally induced mechanical failure of the perovskite (time  &gt;460 years) is unlikely during operating lifetime of any mission. We also share target power conversion efficiencies to manage maximum operating temperature of a perovskite based device.</jats:p><jats:p>This article is protected by copyright.
