Thermal conduction-induced crystallization and achieving high efficiency in HTM-free carbon-based CsPbI2Br solar cells by regulating the dipole moment of aliphatic amine acetate additives

The thermal conduction-induced crystallization and the aliphatic amine acetate additive-optimized dipole moment have successfully modified the properties of the CsPbI 2 Br film, leading to high efficiency in HTM-free carbon-based CsPbI 2 Br solar cells.
