摘要： The present application discloses a method for improving interfacial adhesion of an organic solar cell and an organic solar cell. An elastomer interface layer, which is formed by thermoplastic elastomers, is arranged between at least two adjacent functional layers in the organic solar cell, or, the upper and lower interfaces of at least one functional layer have an enrichment layer formed by enrichment of thermoplastic elastomers. The method comprises: arranging an elastomer interface layer at least two adjacent functional layers, or, enriching thermoplastic elastomers at the upper and lower interfaces of at least one functional layer to form an enrichment layer. According to the present application, the thermoplastic elastomers enriched at the interfaces, or the thermoplastic elastomers used as interface layers alone serve as glue between functional layers. The method disclosed by the present application is simple in process, large in doping window, and small in thickness dependence when independent film formation; the prepared organic solar cell has high photoelectric conversion efficiency, strong adhesion between an active layer and a hole transport layer or an electron transport layer, and good cell mechanical stability.
