Effect of ZnO Concentration on Efficiency in Organic Solar Cells

Abstract

In this study, the effect of the molarity of ZnO synthesized by the sol-gel method on the efficiency of P3HT (Poly (3-hexyl thiophene)):PCBM ((6,6) Phenyl-C61-Butyric acid methyl ester) active layer solar cell was investigated. It was studied at 0.1, 0.3 and 0.5 M values. The efficiency values of the devices were determined with the Keithley 2400 source meter under 100 mw/cm2 solar radiation. In addition, characterization processes were carried out with XRD, UV-Vis and FESEM techniques. After the studies, it was found that 0.1 M synthesis concentration was the most suitable condition and it was determined that 3.09% efficiency could be reached with the device produced under these conditions.
