Problems solved by technology

The research group of Professor Zhang Zhilin of Shanghai University and the team of Academician Xu Xurong of Beijing Jiaotong University have carried out theoretical and experimental research on the dynamic process of excitons in organic luminescence by using strong electric field modulation [Journal of Literature Physics, vol. 47, 1536, 1998; , vol.7, 1030, 2005], but these works mainly obtain a strong electric field by applying a reverse voltage to the light-emitting device, which is not feasible in organic solar cells

Abstract

The invention belongs to the field of organic photovoltaic cells, and particularly relates to an organic small-molecule photovoltaic device based on a three-terminal electrode structure. The organic small-molecule photovoltaic device comprises an ITO layer serving as a first electrode layer, an organic small-molecule donor connected with a conductive face of the ITO layer, an organic small-molecule receptor connected with the other face of the organic small-molecule donor, a second electrode layer connected with the other face of the organic small-molecule receptor, a dielectric layer connected with the other face of the second electrode layer, and a third electrode layer connected with the other face of the dielectric layer, the first electrode layer is connected with a negative electrode of a direct-current voltage source, the third electrode layer is connected to a positive electrode of the direct-current voltage source, and the first electrode layer and the second electrode layer serve as output ends. According to the device, due to the fact that a potential is applied to the two ends of the organic small-molecule photovoltaic device, a strong electric field can be formed in the organic small-molecule photovoltaic device, the exciton disassociation efficiency is improved, and the energy conversion benefit of the organic small-molecule photovoltaic device is improved.

Description

technical field [0001] The invention belongs to the field of organic photovoltaic cells, in particular to an organic small molecule photovoltaic device based on a three-terminal electrode structure. Background technique [0002] Organic solar cells (OSCs) have the advantages of flexibility, low cost, and large-area fabrication, which are of great significance for fundamentally solving the problems of environmental pollution and energy shortage. Low energy conversion efficiency is the main bottleneck restricting its industrialization. The working principle of organic batteries is divided into three processes: light absorption to generate excitons, excitons dissociation into carriers, carrier transport and extraction. At present, a lot of research work is mainly focused on improving the efficiency of OSC by improving its light absorption and carrier transport and extraction [Nano Letters, vol. 12, 2488, 2012; Solar Energy Materials and Solar Cells, vol. 99, 235 , 2012], but ...
