Provided is a thin film semiconductor device that exploits excitonic characteristics of various organic semiconductor materials. The device may include an anode (), a cathode (), and a donor-acceptor heterojunction () disposed between the anode and the cathode. The donor-acceptor heterojunction may further include an acceptor material () having a highest occupied molecular orbital (HOMO) and a lowest unoccupied molecular orbital (LUMO), and a donor material () comprising a hybrid organic-inorganic metal halide perovskite semiconductor. Other embodiments are disclosed and additional embodiments are also possible.
