Abstract

Temperature is one of the most crucial outdoor variables that influence the photovoltaic performance and stability of carbon perovskite solar cells (CPSCs), although not many reports are there on temperature-dependent CPSCs performance based on various mesoscopic structures. This study demonstrates the temperature coefficient (T C) of carbon-based triple and double mesoscopic devices having MAPICL [MAPbI3−x Cl x ] and CSFAMA [Cs0.05(FA0.83MA0.17)0.95Pb(I0.83Br0.17)3] to understand the performance compatibility of different CPSC configurations despite the thermal treatment (MA = methylammonium, FA = formamidinium). While treating a single device in the range of 5 °C–65 °C, MAPICL-based CPSC maintained a power conversion efficiency (PCE) of ∼9%–11.7%. In contrast, CSFAMA-based double mesoscopic devices showed a PCE variation of ∼14%–16% in the same temperature window. The interesting fact of this analysis is that the average T C values for MAPICL and CSFAMA are in the order of 10−4, implying better retention of performance for both mesoscopic devices despite thermal stress. A photoluminescence analysis has been done to understand the temperature-dependent charge transfer properties between the perovskite and transport layer. To the best of our knowledge, this analysis, for the first time, provides insight into the temperature coefficient of different CPSC mesoscopic structures to promote suitable future development.
