Problems solved by technology

[0004] Poly(3,4-ethylenedioxythiophene: polystyrene sulfonate (PEDOT: PSS) is a commonly used anode modification layer material at present, but PEDOT: PSS has strong acidity (pH = 1) and hygroscopicity, resulting in extremely poor device performance. Unstable, when placed in the air without packaging, its energy conversion efficiency will rapidly decay to zero within 7 days
At present, many studies have reported new anode modification layer materials to replace PEDOT:PSS, such as V 2 o 5 , MoO 3 and other metal oxides (J.APPl.Phys.2011,110,033710; Adv.Funct.Mater.2012,22,2594-2605), however, most metal oxides need to be thermally deposited under high vacuum, which greatly increases Reduced the difficulty and production cost of the battery

Abstract

The invention discloses an organic solar cell with MXene as an anode modification layer material and a manufacturing method thereof. An organic solar cell device includes an anode substrate, an anodemodification layer, an active layer, a cathode modification layer, and a cathode layer. The MXene with high conductivity, high transmission of light, and a work function matching with ITO is taken asthe anode modification layer material to manufacture the organic solar cell device. Firstly, the MXene has the high conductivity so that the charge transfer efficiency of the organic solar cell can beeffectively increased; secondly, the MXene can effectively adjust and control the work function, and reduce an interfacial ability between an anode and an active layer; and finally, compared with a corresponding PEDOT: PSS device, by using the cell and the method, higher photoelectric conversion efficiency is achieved.

Description

technical field [0001] The invention belongs to the technical field of organic solar cells, in particular to an organic solar cell in which MXene is an anode modification layer material and a preparation method thereof.
