The field of small molecule solar cells has incredibly developed during the last decade. In fact, their efficiency increased from 3% in 2005 to 13% in 2016. However, they still face a major problem of stability: these cells degrade very quickly in contact with air or under illumination. This study focuses on the uses of measurement techniques to follow the degradation of the cells. We studied the use of both electrical and imaging technics to get a better understanding of the degradation mechanisms aiming to identify the weakest layer and to improve its stability.
