An organic photovoltaic device comprises a first electrode, a first carrier transporting layer, an active layer, a second carrier transporting layer, and a second electrode. The first electrode is a transparent electrode. The active layer includes a conjugated polymer material, which includes a structure of formula I:
wherein R0, R0′, R0″, R0′″, Y1 and Y2 can be the same or different from each other, and independently selected from one of the following groups and their derivatives: C1˜C30 alkyl, C3˜C30 branched alkyl, C1˜C30 silyl, C2˜C30 ester, C1˜C30 alkoxy, C1˜C30 alkylthio, C1˜C30 haloalkyl, C2˜C30 olefin, C2˜C30 alkyne, C2˜C30 carbon chain containing cyano, C1˜C30 carbon chain containing nitro, C1˜C30 carbon chain containing hydroxyl, C3˜C30 carbon chain containing keto, halogen, cyano, and hydrogen. The organic photovoltaic device of the present invention has good power conversion efficiency.
