We report a study on solar cells using pentacene derivatives with triisopropylsilylethynyl substitution at the 6,13-position and 1,3-dioxolane substitution to the terminal benzenoid rings of pentacene as the electron donor and C60 as the electron acceptor. A significant increase in the open circuit voltage (Voc) was obtained in all the pentacene-derivative based cells with the highest Voc as high as 0.90 V, compared to a 0.24 V value for pentacene. The variation in the Voc of the cells is in qualitative agreement with the larger offset between ionization potential of the electron donor and the electron affinity of C60- The power conversion efficiency (η) at 100 mW/cm2 of EtTP-5/C60 cells reached 0.74%, which is comparable to that of a pentacene/C60 cell (0.82%).
