Abstract: Based on some physical and geometric parameters,the influence of internal resistance on the cell performance is analyzed and a semi-empirical mathematical model of the efficiency is built for some configurations of large-scale dye-sensitized solar cells.Three configurations of large-scale cells are investigated,in which the independent units are connected in series and in parallel,as well as in series-parallel.The efficiencies of the three-type large-scale cells are calculated according to their physical and geometric parameters. The applicability of the model is analyzed by comparing the calculated efficiencies with the measured ones.The influences of the physical and geometric parameters on the cell performance are investigated based on the semi-empirical mathematical model.It is found that the optimization of the performance of large-scale cells can be carried by analyzing the influences of physical and geometric parameters using the semi-empirical mathematical model.
