Nanostructured tin oxide (SnO2) is a very promising electron transport layer (ETL) for perovskite solar cells (PSCs) that allows low-temperature processing in the planar n–i–p architecture. However, minimizing current–voltage (J–V) hysteresis

Several photophysical properties of chromophores depend crucially on intermolecular interactions. Thermally‐activated delayed fluorescence (TADF) is often influenced by close packing of the chromophore assembly. In this context, the metal‐organic

The power conversion efficiency of hybrid organic-inorganic perovskite solar cells (PSCs) has been reported to increase spontaneously during storage in the dark and reaches its maximum sometimes only after several days. In most cases, an increased op
