  abstract  = {In this study, a double-donor concept is used to improve the performance of thermally evaporated merocyanine(s)/C60 bulk heterojunction (BHJ) solar cells. It is shown that the co-evaporation of two merocyanine dyes with absorption bands at ~ 500 nm (SW dye) and ~ 650 nm (LW dye), respectively, together with C60 fullerene results in an improvement of open-circuit voltage (VOC), short-circuit current (JSC) as well as total power conversion efficiency (PCE) compared to the best single-donor cell. The enhancement of JSC is attributed to a higher photon harvesting efficiency of the mixed-donor devices due to a better spectral coverage.},
