Performance Evaluation of Electron Transport Layers based on PCBM/P3HT BHJ Organic Solar Cells

Organic solar cells achieved more attention for energy conversion due to a rapid increase in its efficiency and lowest cost. It approaches over 10% in recent lab-scale results. The experiments were conducted in Renewable Energy School, NCEPU, Beijing China. In this study, we focus on the effects of layer thickness, PCE, and FF in organic solar cells. In our experiments P3HT (poly 3-hexylthiophene): PCBM (Polycrystalline C61 butyric acid methyl ester) take an active coating due to its encouraging capability towards efficient fullerene derivative in organic solar cell materials based on donor acceptance polymer. Based on our results we present combined analysis (experimental and theoretical) of OSC based on bulk heterojunctions.
