Abstract
It is highly desirable to develop new solar cells to operate at temperatures higher and lower than standard operational conditions for space and near space applications in future. Herein, we communicate an experimental investigation on temperature-dependent photovoltaic efficiency for perovskite solar cells based on mesoscopic TiO2/Al2O3/NiO/carbon architecture. This perovskite device shows impressive 5% power conversion efficiency at low temperature of 80 K. Therefore, the perovskite solar cells can be precisely characterized in a wide temperature range, which enables unequivocal identification of the contribution of CH3NH3PbI3 perovskite to construction of the built-in electric field, and thus, the temperature dependent photovoltaic parameters. The latter, particularly the open-circuit voltage, shows a strong dependence on the dielectric constant of CH3NH3PbI3.
