Perovskite solar cells are a rising star in the field of thin film photovoltaics. Their efficiency increased to over 25 % within hardly more than a decade and has thus reached values comparable to those of crystalline silicon solar cells. The success of perovskite solar cells lies in the rare combination of easy, low-temperature processability and excellent photovoltaic properties. However, serious challenges are faced when it comes to their long-term stability. Degradation can be induced by almost all external factors, such as light, oxygen or humidity. The degradation mechanisms can be complex and are not yet fully understood. This thesis' work takes a look at the response of perovskite solar cells to several different external stressors, most importantly light, and investigates the role of the hole transport layer. The stability behaviour under illumination is investigated for an organic and an inorganic hole transport layer.
