Owing to a most simple and cost-effective bifacial cell process, the Bifacial PERC + Solar Cells concept has been quickly adopted by various solar cell manufacturers. In this study, we analyze the variation of the PERC + cells performance such as short-circuit current density (Jsc), open-circuit voltage (Voc), fill factor (FF) and output power (Pout) as a function of real albedos of usual surfaces. The simulation is done with PC2D which is a solar cell device simulator that models two-dimensional effects entirely within a Microsoft Excel spreadsheet and allows us to model bifacial cells with illumination of both surfaces simultaneously. So, the simulator can model the equivalent characteristic J - V of the PERC + cells. The results showed us a significant increase in the performance of the PERC + cells; the output power can achieve 35.56 mW/cm2 for the snow. Also the study showed a very good linearity of the four parameters (Jsc,Voc, FF, Pout) with the effective albedo. Therefore, we can predict these parameters for other effective albedos of current surfaces without simulating the PERC + cell.
