TI  - The Effect of Coating Parameter of Active Layer on Performance of Polymer Solar Cells
AB  - In this study, Glass / ITO / PEDOT / Polymer / Al organic solar cell structures were obtained by using glass/indium doped tin oxide (Glass/ITO) transparent metal oxide substrates, PEDOT:PSS and P3HT:PCBM polymer photoactive layer and their performance depending on spin rate and coating technique were investigated. The polymer layer was coated using the spin coating method. Al metal was coated by physical vapor deposition method. By keeping the concentration of the photoactive layer constant, the effects of different spin coating rates, beside static and dynamic coating technique on the power conversion efficiency of the cells and their stability were compared. Electrical characterization of organic solar cells was performed under a solar simulator in a glove box system. By applying voltage between -0.5 V and +1.5 V, I-V (current-voltage) measurements of the solar cells were taken in the light and dark. The power conversion efficiencies of organic solar cells coated at 800rpm, 1000rpm and 2000rpm spin coating speeds, respectively, were observed to be 2.34%, 2.08% and 1.98%.When the average efficiency values considered, static coating at 800 rpm gives more reproducible results in comparison with the other average efficiency values. The average efficiency values for static coating at 800 rpm is observed to be %2.
