Researchers use DBM additive engineering for efficient and stable carbon-based CsPbI2Br perovskite solar cells
Researchers at China's Shanghai University of Electric Power have used dibenzoylmethane (DBM) as a precursor additive introduced in order to regulate the crystallization of CsPbI2Br perovskite while passivating its associated defects.
Inorganic CsPbI2Br perovskite solar cells (PSCs) have attracted massive interest but the tendency towards unruly crystallization and poor film quality of inorganic CsPbI2Br perovskites are major factors limiting their performance improvement. In their recent work, the scientists used DBM additive engineering for efficient and stable carbon-based CsPbI2Br PSCs.
