Title: Low-temperature fabrication of efficient wide-bandgap organolead trihalide perovskite solar cells

A mixed halide perovskite solar cell with a 1.72 eV bandgap is developed by incorporating Br into perovskite through a low-temperature solution process. A high efficiency of 13.1% is achieved by carefully tuning the thickness, morphology, and surface passivation of the perovskite layers. Furthermore, the fabrication techniques and conditions are compatible with future perovskite/Si tandem cell studies.
