1. A polymer, comprising
a first structural unit including a first electron accepting moiety and a first electron donating moiety, and
a second structural unit including a second electron accepting moiety and a second electron donating moiety, the second electron accepting moiety being different from the first electron accepting moiety, and the second electron donating moiety being the same as or different from the first electron donating moiety,
wherein the first structural unit is represented by Chemical Formula 1,
