Abstract

Tin halide perovskites are a growing candidate in the semiconducting materials field due to their band gap, and ability to be doped (specifically p-type doped). Halide perovskites are sensitive to light and air which causes the degradation of the material from its preferred cubic perovskite lattice. This thesis introduces a way of stabilizing bulk CsSnCl3 through the Goldschmidt tolerance factor. It will also introduce potential new ways to p-type dope halide perovskites. We attempted to p-type dope our halide perovskite by substitutional, interstitial, and vacancy doping to increase the carrier concentration to compete with current perovskites. During our trials of different doping techniques, annealing in air presented the most promising results. However, we would need an extensive atmosphere control setup to improve upon these results. Finding a successful p-type doped halide perovskite will push the semiconducting field into a new age of conducting materials.
