In the planar heterostructure of perovskite-based solar cells (PSCs), tin oxide (SnO2) is a material that often used as electron transport layer (ETL). SnO2 ETL exhibits favorable optical and electrical properties in PSC structures. Nevertheless, open circuit voltage (VOC) depletion occurs PSCs due to defects arising from high oxygen vacancy on surface deeper conduction band (CB) energy level SnO2. this research, cerium (Ce) dopant was introduced (Ce-SnO2) suppress VOC loss PSCs. The CB...

To commercialize perovskite solar cells (PSCs), it is crucial to develop cost‐effective, dopant‐free hole transport layers (HTLs) that can be processed at low temperatures. Herein, a small molecular material 4,4′,4′‐Tris[2‐naphthyl(phenyl)amino]triphenylamine (2TNATA) was utilized in inverted PSCs as HTL. The position of the highest occupied orbital energy 2TNATA properly aligned with valence band maximum. Moreover, lower temperatures and shows excellent thermal stability. lead (Pb) on...

Tin–lead (Sn–Pb) mixed perovskite solar cells (PSCs) are promising as bottom subcells in all‐perovskite tandem cells, but the oxidation of Sn 2+ remains challenging for long‐term stability. This study reveals a compositional gradient Sn–Pb films, where excess ions accumulate at surface, intensifying and recombination losses. To address this issue, we introduce PbBr 2 ‐TOAB wet surface treatment strategy during fabrication films. X‐ray photoelectron spectroscopy analysis confirms that...
