Abstract
This paper presents a holistic simulation approach for thin-film photovoltaic modules, incorporating optoelectronic behavior, current conduction, and real-world operating conditions. The model combines a transfer-matrix method, a drift-diffusion model, and a quasi-three-dimensional finite-element Poisson solver. This allows bidirectional calculation from material parameters to energy yield and vice versa, accurate predictions of module behavior, top-down loss analyses, and bottom-up sensitivity analyses. The simulation is valuable for optimizations and determining difficult-to-measure parameters.
