Efficiency Enhancement in Solution-Processed Organic-Inorganic Perovskite Solar Cells

Organic-inorganic lead halide perovskite is a promising candidate in the photovoltaic field due to the combined merits of impressive power conversion efficiencies and relatively cost-effective solution processes. Despite its remarkable success, there is still room for further improvement. This thesis aims to investigate the impacts of morphological microstructure and elemental composition of organic-inorganic lead halide perovskite light absorber on power conversion efficiency, stability and current-voltage hysteresis behaviour of perovskite solar cells.
