The invention discloses an inverted-structure polymer body heterojunction solar cell and a manufacturing method thereof; the polymer body heterojunction solar cell comprises a glass lining, a cathode, a cathode boundary layer, an optical active layer and an anode which are stacked in sequence, and the cathode boundary layer is arranged between the cathode and the active layer. In the method, a conjugated polymer of a polar unit or a corresponding polyelectrolyte, is dissolved in a polar organic solvent to be prepared into solution, wherein the polar unit containsa polar group or an iconicity group and is taken as the cathode boundary layer, and the solution concentration is 0.0001-0.10g/cubic centimeter; and the solution forms the cathode boundary layer on the cathode by adopting manners of spin coating, brush coating, spray coating, dip coating, roll coating, screen printing, printing or inkjet printing. The invention can greatly improve the performance of the polymer body heterojunction solar cell, and can prolong the service life; and the solution processing technology is adopted, the preparing process is simple and the manufacturing cost is low. |
