Abstract: Demand for green and renewable energy is stimulating research into future materials for energy production. Thin films of materials possessing both electron accepting and donating functions play a unique role in solar energy technology because of their lightweight, flexibility, and economical, low-temperature, and large-area fabrication. A [60]fullerene derivative,[6,6]-2-selenyl-C(61)-butyric acid methyl ester (SeCBM), has been synthesized in three steps, namely through Friedel-Crafts acylation of selenophene, hydrazone formation and Bamford-Steven reaction. Organic photovoltaic device incorporating SeCBM and the conducting polymer P3HT exhibited an average power conversion efficiency of 3.26% and a champion efficiency as high as 3.81% under AM 1.5G irradiation.
