Embodiment 1
[0028] A method for improving the performance of a novel organic solar cell generated by interface recombination comprising the following steps:
[0029] The first step is to clean the substrate; put the patterned ITO glass into acetone, ethanol, isopropanol and deionized water for 20 minutes, and then dry it with nitrogen, and set it aside;
[0030] In the second step, the solution was spin-coated with a layer of 39nm-41nm PEDOT:PSS (purchased from Heraeus) on the treated ITO substrate, and baked at 150 °C for 30 min. Put the dried ITO substrate coated with PEDOT:PSS into the vacuum chamber to grow the active layer, interface modification layer and electrodes in sequence;

Abstract
A method to improve the performance of new organic solar cells generated by interfacial recombination to generate carriers. The novel organic solar cell comprises a substrate anode, a hole transport layer, an organic light absorbing layer 1, an organic light absorbing layer 2, an electrontransport layer and a cathodeelectrode from bottom to top. It is characterized in that an effective interface layer intervenes between the organic light-absorbing layer 1 and the organic light-absorbing layer 2, which effectively promotes the interaction between the excitons in the organic light-absorbing layer 1 and the organic light-absorbing layer 2 at the interface, and is more conducive to free current carrying The generation of electrons improves the conversion efficiency of the battery. The present invention intervenes into C by using interface layer Alq3 60 In organic solar cells composed of two materials, F16ZnPc and F16ZnPc, the conversion efficiency of the cells is improved. Intervention of Alq3 increases C 60 The interaction between the excitons of F16ZnPc and the excitons of F16ZnPc on the interface can obtain more free carriers, increase the current and voltage of the battery, and finally improve the conversion efficiency of this type of organic solar cell.
Description
technical field [0001] The invention relates to the technical field of solar cells, in particular to a method for improving the conversion efficiency of a new type of organic solar cell in which an interface layer is inserted into an organic light-absorbing layer to obtain free carriers through interfacial recombination. Background technique [0002] Due to the advantages of simple preparation, light weight, low cost and large-area production, organic solar cells are favored by many researchers. Although the efficiency of organic solar cells has exceeded the energy conversion efficiency of 13%, it is still necessary to further improve the efficiency of the cells for industrialization. In order to further improve the efficiency of organic solar cells, it is very important to understand such cell interface processes, which include interfacial free carrier generation, exciton recombination, charge and exciton interaction and other processes. Among these processes, the generati...
