The steep rise in greenhouse gas emissions and increasing global energy demand ignited the innovation and implementation of clean and green energy resources such as solar energy. Among the photovoltaics (PV) technologies introduced over the last century, the new-born metal halide perovskite based PV thin films established themselves as a potential contender for commercial PV technologies. The champion single-junction perovskite solar cell measured an outstanding power conversion efficiency of over 26% in nearly 15 years of research at a laboratory scale. Despite their rapid success story, the current state-of-art PSC, with formamidinium lead triiodide (FAPbI3) as a light absorber, faces some challenges which prevent them from commercialising the product. This dissertation describes innovative approaches adapted to stabilize and to understand the structure-stability-performance correlations in the photoactive FAPbI3 based PSCs.
