Layer thickness effect on power conversion efficiency of a P3HT:PCBM based organicsolar cell

In recent years Organic Solar Cells have become a prominent topic of research to achieve an optimum efficiency at low cost. By using the GPVDM software on this paper, we have analyzed the effect on power conversion efficiency, changing simultaneously both the polymers and blending layer thickness of P3HT:PCBM based solar cell. Our main goal is to find which layer change keeps the power conversion efficiency output better. After comparing them, the result shows that setting the active layer (P3HT:PCBM) in an optimum fixed value and varying the polymer layer (PEDOT:PSS) gives a better output of PCE. In our paper, from the data in both cases, The highest efficiency is 4.50 percent where P3HT:PCBM layer thickness is 2.2×10-7 m and PEDOT:PSS layer thickness is 1×10-7 m.
