Abstract

We demonstrate for the first time the efficiency improvement of poly(3-hexylthiophene) (P3HT)-fullerene (C₆₀) bulk heterojunction photovoltaic cells by the introduction of functionalized nanodiamonds (NDs) into the photoactive layer. A novel covalently bonded C₆₀ND composite was synthesized via a microwave induced functionalization approach. As compared to control devices with only C₆₀, the addition of carboxylated ND resulted in 53% improvement in short circuit current density J_sc. Such a device design takes advantages of both C₆₀ for electron accepting and ND for efficient electron transport. The results indicate that C₆₀ decorated NDs are promising additives for the performance enhancement of polymer photovoltaic cells.
