Method needing no vacuum process to prepare organic polymer solar cell

Abstract

The invention provides a method needing no vacuum process to prepare an organic polymer solar cell. Indium oxide-tin dioxide (ITO) modified by zinc oxide (ZnO) or titanium oxide (TiO2) and the like, or tin dioxide (FTO) substrate doped with fluorine are taken as a cathode of the battery, and a polymer electrode with high conductivity is taken as an anode of the battery so as to compose the solar cell structure; a layer of hydrophobic polymer active layer modified by self-assembled amphiphilic molecules on water and oil is added between the active layer and the polymer electrode so that the surface of the active layer changes from hydrophobic to hydrophile, thus leading the solution of the water-soluble polymer electrode material with high conductivity to form an electrode film with good film-forming capability on the active layer; the whole preparation process of the solar cell is completed by a solution wet method, the method avoids the defects that in the vacuum evaporating and plating process of the metal electrode, the cost is high, the equipment dependency is strong, the process is complex, the energy consumption is high and the preparation in large area is difficult, furthermore, the method effectively simplifies the preparation process of the device.
