wherein the p-type organic semiconductor compound is a conjugated polymer which includes at least one acceptor unit and at least one donor unit while the n-type organic semiconductor compound is represented by formula I:
wherein SP1 is selected from the group consisting of a vinyl group, a phenyl ring, an electron donating group, a substituted or unsubstituted monocyclic heteroaryl group containing 5 to 20 ring atoms, and a substituted or unsubstituted polycyclic heteroaryl group containing 5 to 20 ring atoms;
Ar0-Ar3 are substituted fused polycyclic heteroaryl groups containing 5-35 ring atoms;
A0-A3 are monocyclic or polycyclic heteroaryl groups containing 5-20 ring atoms and at least one electron-withdrawing group;
B0-B7 are selected from the group consisting of a vinyl group, a phenyl ring, an electron donating group, a substituted or unsubstituted monocyclic heteroaryl group containing 5 to 20 ring atoms, and a substituted or unsubstituted polycyclic heteroaryl group containing 5 to 20 ring atoms;
E0-E3 are monocyclic or polycyclic heteroaryl groups containing 5-20 ring atoms and at least one electron-withdrawing group, defined as different from the SP1 group;
