Harnessing the potential of CsPbBr₃-based perovskite solar cells using efficient charge transport materials and global optimization

Abstract

Here we have done SCAPS simulation for optimizing the performance of CsPbBr3-based PSC. We first optimized the BMC with HTL connected mode and then optimized the CsPbBr3, TiO2, & CFTS layers' various parameters in both with-HTL and without-HTL modes.

Efficiency enhancement of perovskite solar cell devices utilizing MXene and TiO2 as an electron transport layer

“…To develop highly efficient PSCs, a suitable ETL can support a reduction in the recombination currents and improve the transmittance. 48 In the current work, after obtaining the optimum thickness (1.5 μm) of the PAL, a study of ETL thickness variation was conducted, and the optimum ETL thickness was 0.1 μm, which was validated with previous work by Bhattarai et al . 49…”

Achieving above 24% efficiency with non-toxic CsSnI3 perovskite solar cells by harnessing the potential of the absorber and charge transport layers

“…This decline may be due to the cutback of shunt resistance. 75 Another possible reason for this decrement in PCE might be the enhanced charged recombination rate at higher temperatures due to the drop in charge recombination resistance.…”

Optimized High-Efficiency Solar Cells with Dual Hybrid Halide Perovskite Absorber Layers

“…The inherent volatile nature of the perovskites with the organic MA + cation affects the efficiency and the performance of the perovskite solar cells with the MA + cation containing perovskite as the absorber material . More specifically, the methylammonium lead halide perovskite materials have garnered significant attention due to their exceptional optoelectronic properties, which result in high power conversion efficiencies in solar cells. , The reason behind choosing MA + is primarily its ability to exhibit desirable optoelectronic properties such as direct bandgap, high carrier mobility, and long diffusion lengths. These features are crucial for efficient light absorption and charge transport within a solar cell device.…”
