Soluble functionalised fullerenes for photovoltaics

Two mono-adducts of fullerene C 60 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/cm 2...

Zusammenfassung:	Two mono-adducts of fullerene C 60 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/cm 2, 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.
