Optimization of the Active Layer P3HT:PCBM for Organic Solar Cell

ITO/PEDOT:PSS/P3HT:PC60BM/Mg-Al organic solar cells (OSCs) were fabricated depending on optimization of Poly(3-hexylthiophene-2,5-diyl) (P3HT) and phenyl-C61-Butyric-Acid-Methyl Ester (PC60BM). The the active layer, P3HT:PC60BM, was carried out under different spin frequencies coating from 900 to 3000 rpm. post-production annealing temperature all prepared OSC studied 130 190 °C. holes transport poly(3,4-ethylene dioxythiophene) polystyrene sulfonate (PEDOT:PSS), constant conditions rpm for 35 s, 178 °C 15 min. From our study, optimum P3HT:PC60BM rpm, 160 5 J-V parameters values JSC = 12.01 mA/cm2, VOC 660 mV, FF 59%, PCE 4.65%, EQE 61%. A complete with acceptable efficiency designed using simple low-cost techniques that may be utilized in industry. Furthermore, cost synthesized cell is projected around 1 $/cm2, goal lowering increasing future by incorporating more commercial nanostructured electron/hole components.
