Abstract

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 (V_oc) was obtained in all the pentacene-derivative based cells with the highest V_oc as high as 0.90 V, compared to a 0.24 V value for pentacene. The variation in the V_oc 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%).
