The performance of small molecular organic photovoltaic materials is typically limited by their low exciton diffusion lengths' ? solubility, and Poor energy level alignment with fullerenes so that the design and synthesis of new materials remain a top priority. To overcome these limitations, we explored the use of an iridium complex as a donor material with the potential for compatibility with solution processing, long exciton diffusion length and easy molecular modification for tunable optical or electrical properties. A bilayer device with a cyclometalated iridium complex and C-60 resulted in a power conversion efficiency as high as 2.8%. Furthermore, a V-OC of 1 V was achieved in the bilayer device despite an estimated exciton energy of only 1.55 eV, and the device showed minimal temperature and light intensity dependence.
