Perovskite solar cells have become the dominant silicon alternate in the last few years. Within this thesis, thermal co-evaporation method is put forth as a potential method for producing high efficiency solar cells. Focus is given to producing higher efficiency cells primarily by monitoring and altering the contribution of the component materials of lead iodide and methylammonium iodide, as well as the overall thickness of the active layer, and the concentration of the poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine hole transport layer.
