POLYMER SOLAR CELL AND PREPARATION METHOD THEREOF

摘要

Disclosed are a polymer solar cell and a preparation method thereof. The preparation method comprises: successively preparing on a clean glass substrate(1), a cathode (2), an electronic buffer layer (3) and an active layer (4) by the steps of dissolving poly(3,4-ethylenedioxythiophene) and polymerized p-styrene sulphonic acid, dissolving zinc oxide into acetic acid to obtain a zinc oxide solution, mixing the zinc oxide solution with the solution of poly(3,4-ethylenedioxythiophene) and polymerized p-styrene sulphonic acid to obtain a mixed solution, spin-coating the mixed solution on the active layer(4) and then by drying to obtain the anode (5), and finally obtain the polymer solar cell. Using the refractive index difference between the anode and the active layer, the light absorption and energy conversion efficiency of a polymer solar cell are improved, resulting in a simple preparation process, and the use of a reversed structure facilitates improving the lifetime of a polymer solar cell and enables the product and method to have industrialized application prospects.
