NOVELTY - An organic photovoltaic cell has substrate, anode, hole-transport layer, active layer, electron-transport layer and cathode, laminated sequentially. The hole-transport layer contains polystyrene sulfonate-doped poly(3,4-ethylenedioxythiophene). The anode contains electron-donor material and electron-acceptor material. The electron-donor material contains organic compound (I). The electron-transport layer contains 60C carbon compound and its derivatives or 70C carbon compound and its derivatives. The hole-transport layer contains polymer containing monomer (II).    USE - Organic photovoltaic cell (claimed).    ADVANTAGE - The organic photovoltaic cell has high energy conversion efficiency and open circuit voltage.
