| Popis: | 8th World Conference on Photovoltaic Energy Conversion; 415-418 Since the photoconversion efficiency of the silicon-based solar cells (SCs) is approaching their theoretical fundamental limit close to 29%, further improvement of their performance requires theoretical modeling and/or numerical simulation to optimize the SCs parameters and their design. For several types of high-performance silicon-based SCs with both flat and textured top surfaces, we (i) analyzed experimentally key characteristics, namely external quantum efficiency (EQE), short-circuit current density JL(d), open-circuit voltage VOC, I-V curves and the efficiency ; (ii) modeled these characteristics by a semi-analytical approach, developed by the authors, and (iii) numerically simulated using Quokka, SunSolve and other dedicated software. Analyzing and comparing the combined experimental, modelled and simulated results provide valuable information to further improve the design and enhance the SCs performance. The experimental EQE() curves for high-efficiency silicon planar and textured SCs have been analyzed in terms of the base thickness dependent short-circuit current density JL, calculated using the empirical formula for EQE(), and the same parameters were simulated using Quokka 3. The theoretical and modeling results, dependent on the SCs type and structure, recombination parameters, radiation intensity, etc., agree well with the experiment for the considered IBC type flat and textured SCs. |
