Organic solar cell additive

A novel organic solar cell additive includes a surface active agent, a dispersing agent, and a catalyst. The surface active agent (1) and the dispersing agent (2) are used to make the additive be uniformly mixed with a hole transmission layer; and the catalyst (3) reduces molecular free energy, and maintains an appropriate molecular roughness, so that an electronic transmission layer and an active layer form a maximum contact area and a contact resistance is reduced. The surface active agent (1) is glycerol and derivatives thereof, such as a sodium glycerine; the dispersing agent (2) is an ascorbic acid and derivatives thereof, such as a sodium ascorbate; and the catalyst (3) is a lactic acid and derivatives thereof, such as a sodium lactate.
