2D Layered (CH3NH3)3Sb2ClxI9−x Lead-Free Perovskite for Weak Light Detection
Weak light detection is a current research topic and chlorine-containing lead-free perovskite materials are promising. In this research work, Cl-incorporated methylammonium Sb mixed halide perovskite (CH3NH3)3 (Sb)2(Cl)X I(9−X) derivatives were investigated for weak light detection. We have devised a solution-processable slow crystal growth (SCG) to fabricate 2D layered (CH3NH3)3 (Sb)2(Cl)X I(9−X) lead-free perovskite microcrystals. SCG facilitate only 1.51 atomic percent chlorine incorporation confirmed in FESEM-EDS analysis and band gap 1.98 eV determines the SCG grown lead-free perovskite molecular formula to be (CH3NH3)3 (Sb)2(Cl)X I(9−X). FTO/ (CH3NH3)3 (Sb)2(Cl)X I(9−X) PMCs/FTO self-powered photodetector detect 400 nm, 1µW cm−2 weak optical signal. (CH3NH3)3 (Sb)2(Cl)X I(9−X) respond to weak optical signals in the 300–600 nm wavelength range. Also, (CH3NH3)3 (Sb)2(Cl)X I(9−X) exhibit a high reflectance (> 70%) for the wavelength above 600 nm with its inherent thermodynamic stability is a candidate for use as a reflective layer in tandem solar cells.
