| description | Inorganic CsPbIBr
perovskite solar cells (PSCs) have accomplished many milestones, yet their progress has been constrained by ion migration and phase separation. This study explores the modulation of perovskite crystallization kinetics and halide ion migration through chlorobenzene (CB) antisolvent with bis(pentafluorophenyl)zinc (Zn(C
F
)
) additive. The photoluminescence and absorption spectra reveal the significantly reduced phase segregaton in CsPbIBr
film treated by CB with Zn(C
F
)
. Moreover, this research analyzes the CsPbIBr
film's free carrier lifetime, diffusion length, and mobility using time-resolved microwave conductivity and transient absorption spectroscopy after Zn(C
F
)
modification. Consequently, the modified CsPbIBr
PSCs offer a 12.57% power conversion efficiency (PCE), the highest value among CsPbIBr
PSCs with negligible hysteresis and prolonged stability. Furthermore, under 1-m-deep water, CsPbIBr
PSCs display a PCE of 14.18%. These findings provide an understanding of the development of phase-segregation-free CsPbIBr
films and showcase the prospective applications of CsPbIBr
PSCs in underwater power systems. |
