Comparative Analysis of a Bifacial and a Polycrystalline Solar Cell Device Performances by Optimizing Effective Parameters Using PC1D

As a source of clean energy, solar cells have become a prominent topic of research in recent years to achieve its most favorable efficiency at a low fabrication cost. In this paper, by using PC1D simulation software we have investigated the comparisons of the device performances and power conversion efficiencies between two types of silicon solar cells: bifacial solar cell and polycrystalline solar cell respectively. The main objective of this paper is to find which solar cell has a better device performance and efficiency level by varying the thickness, emitter doping level and bulk recombination lifetime. Apart from these parameters, the rest of the parameters are kept in similar conditions and an optimal range was maintained to conclude the result. After all the simulations it can be deduced that a bifacial solar cell has a better device performance and power conversion efficiency. Maintaining all conditions of the fabrication process of solar cells, in our work the highest achievable efficiency of bifacial solar is 16.76% which is greater than polycrystalline solar cell.
