An improved theoretical model was developed and applied to optimize characteristics of highly efficient textured solar cells. An empirical formula for external quantum efficiency was proposed to compare theoretical results with experimental spectral dependencies, allowing the optimization of key parameters in the solar cells. Theoretical results were used to optimize parameters such as base thickness and doping level of the solar cells.
We developed and applied an improved theoretical model to optimize characteristics of highly efficient textured solar cells (SCs). The model accounts for all recombination mechanisms, including nonradiative exciton recombination and recombination in the space-charge region (SCR). To compare the theoretical results with an experiment, we proposed empirical formula for the external quantum efficiency (EQE), which describes its experimental spectral dependencies near the absorption edge. The proposed approach allows modeling short-circuit current and photoconversion efficiency in the textured crystalline silicon solar cells. The theoretical results, compared to the experimental measurements, were used to optimize the key parameters of the SCs, such as the base thickness, doping level and others.
