Examining stability in organo-halide perovskite solar cells

Stability in perovskite solar cells (PSCs) is a topic heavily studied by the research community in recent years, despite the impressive efficiencies achieved with these remarkable optically-active materials for photovoltaics (PV) applications. Specifically, moisture ingress and ion-transport need to be reduced to attain a lifetime sufficient for a commercially viable PV technology. The stability issues arise from a number of factors, including the susceptibility of the absorber to environmental conditions. In this work, we will discuss our efforts to examine the stability in PSCs from multiple angles, which include examining the role of interface layers, collector electrode material used, and the chemistry and crystalline structural of the absorber itself.
