Investigation of Active Layer Thickness Variation on the Performance of Bulk Heterojunction Organic Solar Cells
The active layer thickness dependence of bulk heterojunction organic solar cells with two different donor and acceptor material combination is studied. For one organic solar cell, poly(3-hexylthiophene): P3HT is taken as the electron donor with phenyl-C61-butyric acid methyl ester: PCBM as the electron acceptor. Another active layer blend has poly(9,9-dioctylindenofluorene-co-benzothiadiazole): PIF8BT and N′-bis(1-ethylpropyl)-3,4,9,10-perylene tetracarboxy diimide: PDI as the donor-acceptor material. We simulate the cells with the two different active layer combinations and investigate the organic solar cell parameters with respect to the active layer thickness variation.
