Organic solar cells as an alternative to inorganic solar cells are the devices that absorb the Sunlight with an active polymer layer and, directly convert into electrical energy. Organic/polymers that have unique design possibilities such as the coating on large surfaces, low fabrication cost, flexible, easy to produce, etc. investigate as an active polymer layer and promise in solar cell production. In this study, the modelling and simulation of organic solar cells with PEDOT:pss (OSC1), PDTS: DTffBT (OSC2) and P3HT (OSC3) as active layer are presented in order to investigate the effects of the layer thicknesses on the power conversion efficiency. Experimentally, the electrical and optical parameters by using the GPVDM software program are calculated and analysed. The electronic parameters such as the open-circuit voltage (Voc), the short-circuit current (Isc), the maximum power (Pmax), the fill-factor (FF), the power conversion efficiencies (PCE), etc. are obtained for each organic solar cells. Additionally, the layer thicknesses of the PEDOT:pss (OSC1), PDTS: DTffBT (OSC2) and P3HT (OSC3) for each organic solar cells are changed from to 100μm to 100nm and then, the results are compared with each other. The simulation results indicate that the power conversion efficiencies for the OSC1, OSC2, OSC3 are 16.22%, 17.49% and 7.10% for the optimised layer thickness i.e. 100μ, respectively.
