Abstract
The present invention, in one aspect, relates to a solar cell. In one embodiment, the solar cell includes an anode; an active organic layer comprising an electron-donating organic material and an electron-accepting organic material; a semiconducting layer formed between the anode and the active organic layer; and an electron-blocking layer (EBL) formed between the semiconducting layer and the active organic layer, where the EBL is transparent and adapted for blocking electron leakage from the active organic layer to the anode while transporting holes from the active organic layer to the anode.
