Organic-inorganic hybrid perovskites have been representing a scientific breakthrough in the photovoltaic field since 2009 when they were applied to replace photoactive dyes in hybrid solar cells. Further development has been highly boosted by a large and enthusiastic effort up to a current maximum efficiency of 24.2%. The exceptionality of this class of materials resides in their soft character combined with long diffusion lengths of the photo-generated carriers, a wide absorption range and direct tunable bandgap. Nonetheless, the low structural stability of the hybrid perovskites, primary MAPbI3, risks to severely retard their wide-range applications in low-cost/high-yield devices. Focused research is currently relating instability sources and degradation mechanisms with the operation conditions, including temperature, illumination, humidity, contaminants and interfacing materials. Although the overall …
