Influences of organic cation and hydrochloric acid additive on the morphology and photoluminescence of HC(NH2)2PbBr3 films
Source abstract
Abstract
Abstract The hydrohalic acid additives have been used in perovskite thin films to improve the film morphology and optical properties. However, our study demonstrated that the hydrochloric acid (HCl) additive greatly improved the surface coverage but lowered the photoluminescence (PL) emission intensities of HC(NH2)2PbBr3 (HC(NH2)2 = FA) films. The effects of organic cation and hydrochloric acid additive on the morphology and photoluminescence of FAPbBr3 films were investigated. We found that FAPbBr3 films prepared with HCl additive in low FABr concentration environment displayed good film quality but weak PL emission intensity. The optical properties of FAPbBr3 films have close relationship with FABr concentration. The optical absorption edge of FAPbBr3 showed a blue shift with increasing the FABr concentration. The strong PL emission intensities of FAPbBr3 can be obtained from the solutions with high FABr concentration.
