Molecular umbrella can protect solar cells by blocking ion migration

Perovskites are semiconducting materials that have rapidly transformed the field of optoelectronics, demonstrating outstanding performance in light-emitting diodes (LEDs) and photodiodes. For their unique properties, they have also gained attention in photovoltaics. After almost two decades of intensive research, this "wonder" class of materials could provide a cost-effective route to significantly enhance energy generation in both large-scale solar farms and rooftop panels. However, maintaining high efficiency upon scaling up device fabrication still remains difficult for the processes that occur on the molecular level, limiting long-term stability of perovskite materials.
