So we chose that part to beginning study of the material and all parameters effects in environmental condition because the solar cell working in environment. In this study the fabrication of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl C61-butyric acid methyl ester (PCBM) blend flexible thin film using spin coating was reported. Process parameters like solvent, electron donor to acceptor ratio, concentration and temperature were also studied. We used solvent systems to make active layer of P3HT:PCBM composite and PEDOT:PSS as a buffer layer. Highest absorption was obtained for the flexible thin film made with 1:1 and 1:0.75 ratio of P3HT to PCBM. Chloroform solvent in 40 gm/ml concentration at 90 ~C was the optimum conditions to make flexible device.展开更多
