The invention discloses a novel
polymer solar cell with a dual-
electron transmission layer. The novel
polymer solar cell comprises a transparent conductive substrate; an inorganic / organic material laminated
electron transmission layer, wherein the
electron transmission layer is of a laminated structure formed by an inorganic material
nano zinc oxide and an organic material PFN, and
zinc oxide is annealed with a rapid heat treatment method; a luminous
absorption layer; a cavity transmission layer; and a
metal electrode. The high-efficiency
polymer solar cell can be prepared by a solution method, the cost is low, and the large-scaled production is facilitated. The novel dual-
electron transmission layer is adopted, to that the good electric
conductivity of the inorganic material is inherited, and an interface
dipole layer generated by the
organic matter facilitates the extraction and transmission of electrons. Rapid heat treatment is carried out on the inorganic material, the
crystallinity of the material is further improved, and the
electron mobility is increased. The
polymer solar cell subjected to the rapid heat treatment and provided with the dual-
electron transmission layer has the advantages that compared with a device using a single polymer layer as the
electron transmission layer, the performance is improved by 23% and reaches 9.31%.
