Perovskite solar cells are the fastest advancing solar technology to date with efficiencies increasing from 3.9% to more than 21% within a few years. They have emerged as a possible alternative to silicon photovoltaics due to their exceptional photovoltaic performance, light absorbing properties, and low-cost fabrication with methylammonium lead iodide (CH3NH 3PbI3) getting considerable interest in research and development. However, there are still many challenges that must be addressed for perovskite solar cells to replace contemporary solar cells, such as improving their stability, making them nonhazardous, further increasing their efficiency, and developing better techniques for large scale fabrication. In this thesis, a low temperature flexible perovskite solar cell that uses a mesoporous TiO2 layer as the electron transport layer was developed capable of producing efficiencies up to 5% for active areas of 0.01cm2 and 1.6% for active areas of 0.12cm2.
