Comparative study of distinct halide composites for highly efficient perovskite solar cells using a SCAPS-1D simulator.

This research investigates the influence of halide-based methylammonium-based perovskites as the active absorber layer (PAL) in perovskite solar cells (PSCs). Using SCAPS-1D simulation software, the study optimizes PSC performance by analyzing PAL thickness, temperature, and defect density impact on output parameters. PAL thickness analysis reveals that increasing thickness enhances for MAPbI and MAPbIBr, while that of MAPbBr remains steady.

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

Lead toxicity is a barrier to the widespread commercial manufacture of lead halide perovskites and their use in solar photovoltaic (PV) devices. Eco-friendly lead-free perovskite solar cells (PSCs) have been developed using certain unique non- or low-toxic perovskite materials. In this context, Sn-based perovskites have been identified as promising substitutes for Pb-based perovskites due to their similar characteristics.

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

Perovskite solar cells (PSCs) have become a possible alternative to traditional photovoltaic devices for their high performance, low cost, and ease of fabrication. Here in this study, the SCAPS-1D simulator numerically simulates and optimizes CsPbBr-based PSCs under the optimum illumination situation. We explore the impact of different back metal contacts (BMCs), including Cu, Ag, Fe, C, Au, W, Pt, Se, Ni, and Pd combined with the TiO electron transport layer (ETL) and CFTS hole transport layer (HTL), on the performance of the devices.

Combined DFT, SCAPS-1D, and wxAMPS frameworks for design optimization of efficient CsBiAgI-based perovskite solar cells with different charge transport layers.

In this study, combined DFT, SCAPS-1D, and wxAMPS frameworks are used to investigate the optimized designs of CsBiAgI double perovskite-based solar cells. First-principles calculations are employed to investigate the structural stability, optical responses, and electronic contribution of the constituent elements in CsBiAgI absorber material, where SCAPS-1D and wxAMPS simulators are used to scrutinize different configurations of CsBiAgI solar cells. Here, PCBM, ZnO, TiO, C, IGZO, SnO, WS, and CeO are used as ETL, and CuO, CuSCN, CuSbS, NiO, P3HT, PEDOT:PSS, spiro-MeOTAD, CuI, CuO, VO, CBTS, CFTS are used as HTL, and Au is used as a back contact.
