Strain engineering improves the photovoltaic performance of carbon-based hole-transport-material free CsPbIBr < sub > 2 < /sub > perovskite solar cells

Chem Commun (Camb). 2024 Apr 17. doi: 10.1039/d4cc01012d. Online ahead of print.ABSTRACTAlkylamines with different chain lengths including n-butylamine, n-hexylamine, and n-octylamine, are applied to regulate the CsPbIBr2 perovskite film quality by strain engineering. The status of residual strains is controllably modulated, resulting in improved efficiency and stability of carbon-based hole-transport-material free CsPbIBr2 perovskite solar cells.PMID:38629259 | DOI:10.1039/d4cc01012d
