An organic photovoltaic cell is provided, which includes an organic active layer, a light-transmissive electrode, a reflective electrode, and an optical film. The light-transmissive electrode and the reflective electrode are respectively disposed at two opposite sides of the organic active layer. The optical film and the organic active layer are respectively disposed at two opposite sides of the light-transmissive electrode. The optical film has an inner surface and an outer surface opposite to the inner surface. The transmittance of the optical film is higher than 90% when light enters the optical film from the outer surface. The reflectivity of the inner surface is higher than 10% when the light enters the optical film from the inner surface. The haze of the optical film is higher than 90%.
