The hybrid approach to modelling and simulation of thin film solar cells with a metal front grid on top of the transparent conductive oxide based electrode will be presented. A 3D model with high aspect ratio of device thickness (100s of nm) and its length and width (mm and cm range) was divided into two coupled models with different number of spatial dimensions (a 1D and a 3D model) on different length scales. The first one covers the modelling on the material stack level. The second model is coupled with the first and it takes into account the photovoltaic device’s geometry. This approach enables the separation of the technology-dependent material simulation from the device shape and front grid design simulation. The metallization in the form of parallel fingers was investigated and optimized for the described case study. Finally, the efficiency of solar thin-film modules using optimized cells with different widths will be explored, thus enabling the tuning of the output voltage of the solar module while the power output remains unchanged.
