Abstract

Two mono-adducts of fullerene C60 have been synthesised using new aryl azides in good yields. These were characterized with spectroscopic techniques and then used to fabricate bulk heterojunction solar cells with regioregular poly (3-hexylthiophene) (RR-P3HT). A photocurrent density of 3.89 mA/cm2, open-circuit voltage of 0.53 V and power conversion efficiency of 0.89% for adduct I and photocurrent density of 2.93 mA/cm 2, open-circuit voltage of 0.53 V and power conversion efficiency of 0.71% for adduct II have been achieved.
