Abstract
In this article the optical properties of poly (3-hexylthiophene): Indene-C60 bisadduct (P3HT:ICBA) layers were examined. The good absorption of the blend in the visible spectra of light allows using ICBA as acceptor material for the fabrication of organic solar cells. The structure of the realized device is glass/ITO/ZnO(np)/P3HT:ICBA/PEDOT:PSS/Ag.
Indene-C60 bisadduct (ICBA) has been used as acceptor molecule to achieve open-circuit voltage Voc = 0.8 V when poly (3-hexylthiophene) (P3HT) is used as donor polymer. Compared to [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) a shift in open-circuit voltage ∆Voc ≈ 0.2 V is observed. This study shows that the parameters of the cells with ICBA are improved compared to PCBM. An efficiency of 5.85% is obtained with ICBA and 3.89% is obtained with PCBM.
