Monolithic perovskite/c-Si tandem solar cell: Progress on numerical simulation

Abstract

AbstractPerovskite/c-Si tandem solar cell (TSC) has gradually become the hottest research topic in photovoltaic field for global carbon neutrality. Here we review the recent progress of numerical simulation studies of monolithic perovskite/c-Si TSC in terms of the methodology, light harvesting management, and energy yield aspects. It is summarized that the integration of physical fundamentals of the methodology, optimization of modeling and parameter correction can bring simulation results closer to experiments. Based on theoretical analysis of light harvesting management, we have demonstrated that textures can enhance light trapping capability and resonance absorption. The advances of bifacial perovskite/c-Si TSC have been particularly reviewed in simulation calibration (current matching loss approach) and low-cost strategy (ultrathin Si). Finally, through the energy yield analysis of the monofacial and bifacial TSC, we have innovatively proposed that spectral variables, effective albedo and top-cell bandgap should be integrated into cell preparation and module installation. This in-depth numerical simulation review provides a guidance for experimental preparation of low-cost and high-efficiency perovskite/c-Si TSC.
