Helical interfacial modulation for perovskite photovoltaics
Hybrid metal halide perovskites have demonstrated remarkable performances in modern photovoltaics, although their stabilities remain limited. We assess the capacity to advance their properties by relying on interfacial modulators featuring helical chirality based on P,M-(1-methylene-3-methyl-imidazolium)[6]helicene iodides. We investigate their characteristics, demonstrating comparable charge injection for enantiomers and the racemic mixture. Overall, they maintain the resulting photovoltaic performance while improving operational stability, challenging the role of helical chirality in the interfacial modulation of perovskite solar cells.|Helical modulators improve the operational stability of perovskite solar cells without a significant effect on photovoltaic characteristics, challenging the role of chiral interfacial modulators in hybrid perovskite photovoltaics.
