Selection of efficient HTL for lead-free Cs2TiBr6-based PSC with relative permittivity, & carrier life time optimization: a theoretical study
This research work represents a comparative study of the regular n-i-p heterojunction structure ofCs2TiBr6 single halide Perovskite solar cells (PSCs) using the SCAPS-1D software framework under ambient conditions.We have studied the performance optimization of different hole transfer layers (HTLs)P3HT, CuO, Cu2O, and MoO3 respectivelyfollowed by optical, and electronic properties analysis to identify the appropriate HTL for the FTO/TiO2/Cs2TiBr6/HTL/Ag-based PSC module.Other performance parameters, C-V (Capacitance–voltage), and M-S (Mott-Schottky) plot analysisshows thatMoO3HTL has better photovoltaic (PV) performance characteristics. Cs2TiBr6/MoO3 based PSC shows higher open circuit voltage (VOC = 0.2434 V), power conversion efficiency (PCE = 4.8%)compares to Cs2TiBr6/ P3HT, Cs2TiBr6/CuO, Cs2TiBr6/Cu2O based PSC. On the other look, investigated PSC material Cs2TiBr6/MoO3has shown visible light emission edge at 190 nm wavelength, superior semi-circular shape, higher PV parameters in the context of variation in relative permittivity, carrier lifetime, diffusion length, and defect density at the interfaces.The optimized carrier lifetime of Cs2TiBr6/MoO3-based PSC has been recorded as 50 ns at 500 nm thickness of active material.
