Abstract

Chemistry Chemistry, Physical Energy & Fuels Materials Science Materials Science, Multidisciplinary Physical Sciences Science & Technology Technology
An extremely fast annealing technique for mixed-halide perovskite solar cells is presented. Using photonic flash sintering, we have demonstrated that a spin-coated perovskite precursor may be fully annealed in as little as 1 ms. Devices annealed in 1.15 ms yielded power conversion efficiencies (PCEs) of upto 11.3% compared to 15.2% for samples annealed for 90 minutes on a hotplate.
