Özet

The photovoltaic performances of inverted organic solar cells including P3HT:PCBM active layer with perylene diimides (PDIs) substituted with different subunits at bay positions of perylene ring were investigated. The improvement of photoluminescence intensity for P3HT:PCBM blend was achieved by the increase of PDI1 additive amount from 6.6 to 10 wt%. In P3HT:PDI1:PCBM ternary blend, preliminary results obtained from cell measurements indicated that PDI1 dopant has improved the cell efficiency by 38% compared to the control cell. Carrier mobility studies revealed that electron or hole mobility capacities of the perylene additives in ternary blends gave a more detailed explanation for efficiencies both binary and ternary systems.
