The application of perovskite photovoltaics is hampered by issues related to the operational stability upon exposure external stimuli, such as voltage bias and light. dynamic control properties materials in response light could ensure durability solar cells, which especially critical at interface with charge-extraction layers. We have applied a functionalized photochromic material based on spiro-indoline naphthoxazine hole-transport layers corresponding cells aim stabilizing them demonstrate photoinduced transformation combination techniques, including transient absorption spectroscopy Kelvin probe force microscopy. As result, derivative offers improvements photovoltaic performance stability, highlighting potential strategies photovoltaics.
