In order to study the influence of the device shape on the solar cell device parameters, we systematically varied its geometry. By determining all sheet and contact resistances in the device, we were able to correlate the series resistance with the geometry of the device using a simple model for its calculation. As a result, rules for optimal design of solar modules were derived. However, further refinement of the calculation is required in order to minimize the deviation between calculus and experiment.
