Abstract

The invention belongs to the fields of materials and devices of organic photovoltaic cells, and particularly relates to an organic photovoltaic cell which has long triplet state service life and takes a Cu (I) complex phosphorescent material as the component of a doping agent. The organic photovoltaic cell comprises indium tin oxide (ITO) conductive glass (1), an electronic donor layer (2) deposited on the ITO conductive glass (1) in a vacuum way, a mixed layer (3) deposited on the electronic donor layer (2) in a vacuum way, an electronic acceptor layer (4) and a cathode (5), wherein the mixed layer (3) is used for mixing an electronic donor CuPc and a Cu (I) complex. The organic photovoltaic cell can be used for prolonging the length of excition diffusion, and is simple in synthesis method and easy to prepare.

Description

technical field

[0001] The invention belongs to the field of materials and devices of organic photovoltaic cells, and in particular relates to an organic photovoltaic cell in which a Cu(I) complex phosphorescent material with long triplet lifespan is used as a dopant component. Background technique

[0002] Compared with traditional inorganic photovoltaic cells, the preparation process of organic photovoltaic cells is simple, and it has the advantages of large manufacturing area, low cost, simplicity, and flexibility. In 1986, Tang reported a single donor-acceptor heterojunction organic solar cell. Because of its potential broad application prospects, academia and business circles have launched in-depth research on organic photovoltaic cells. The current study found that the diffusion distance of excitons is only 10 nm, so the effective thickness of the film in the bilayer structure is about 20 nm. Therefore, the carriers need to travel a certain distance in the two layers ...
