Title: Tuning the Electrophysical Parameters of Silicon Bottom Layers in Tandem Perovskite-Based Solar Cells
Keywords: energy band bending, perovskite, tandem solar cell, textured solar cell

Abstract: Texturing of the solar cell surface, essential for light trapping, introduces complexities that affect charge extraction. Numerical simulations using PC1D software were performed to analyze the energy band bending and carrier densities near the textured surface. The results indicate that texturing significantly influences these parameters within the first 10 micrometers of the silicon layer, enhancing charge separation but also posing challenges related to surface recombination. Optimizing texturing processes, doping profiles, and interface properties is crucial for maximizing the efficiency of tandem solar cells. Experimental validation included thermal diffusion and oxidation processes to achieve specific doping concentrations and resistivity, with resulting specific resistance of 2.61 Ω.cm and a doping concentration of 6×1015 cm-3, For this cell and a chess matt ring-shaped texturing an efficiency of 17.6% was achieved without optimization of the other coatings.
