Device physics of hybrid perovskite solar cells

There is a current global demand for clean and renewable energy sources. The use of fossil fuel (non-renewables) is expected to dwindle because of their high cost (e.g. oil wells need to be dug deeper and in sensitive reservoirs thus increasing production costs) and environmentally damaging byproducts. An efficient option is harvesting energy from the Sun. Hybrid perovskite solar cells (PSCs) provide an attractive way to convert solar energy into usable energy. The commercial success of PSCs hinges on them having high efficiencies and improved stability, so that the associated energy and money payback period is as small as possible. To achieve these goals, a deeper understanding of the fundamental physical processes that govern their operation is required. This thesis focuses on physics of hybrid perovskite solar cells, providing insight in to performance-limiting physical processes.
