Structural Design and Photovoltaic Performance Study of the Organic Ternary Hybrid Heterojunction Solar Cell
A theoretical model of Ag/Au micro and nano structure was established based on the optical near-field excitation and the local field theory by optical simulation software. The new structure of polymer/fullerene solar cells based on the perfect absorber are demonstrated by high resolution lithography technology, and the perfect all-optical wavelength absorption of the solar spectrum from the ultraviolet to near-infrared light is achieved in order to improve energy conversion efficiency of solar cells. At the same time, the new donor materials was designed and prepared which have similar structure, good "compatibility" and complementary absorption spectrum. The ternary solar cells were prepared which fabricated with two polymers as the electron donors blended with fullerene acceptor to maximize the matching of the solar spectrum. This method can effectively improve the response of the device to the sunlight, produce a large number of optical carriers, and greatly improve the short circuit current density and the open circuit voltage. Then the new polymer solar cells with high efficiency and high stability are expected.
