- Abstract
CHNHPbI and CHNHPbIBr crystal powders and thin films with chemical formula CHNHPbIBr have been synthesized by reacting methylammonium bromide/iodide with lead iodide. The films were fabricated by a low-temperature solution process using the spin-coating method followed by thermal annealing, which is an effective means for controlling the composition and morphology of the CHNHPbIBr thin films. The resulting perovskite films exhibit good optical absorption and crystalline structure, being promising for potential application as light absorbers in future solar cells.
