Abstract

The invention discloses a laminated organic photovoltaic cell which takes three kind triple layer organic heterojunction film as the middle electrode. The advantages of taking organic heterojunction film as the middle electrode are as follows: avoid photo production exaction quenching caused by introduction of metal particle; lost nearly no energy from the effective recombination of electrons andholes at the heterojunction interface; reduce internal resistance because of good electric contact with organic optical activity layer; thereby increasing the efficiency of device.

Description

Technical field [0001] The invention relates to a laminated organic photovoltaic cell using an organic heterojunction film as an intermediate electrode. Background technique [0002] In recent years, organic photovoltaic devices have shown application potential in cheap photovoltaic cells, and energy conversion efficiency is an important indicator of the practical application of photovoltaic cells. In 1986, the American Applied Physics Letters (C.W. Tang, Applied Physics Letters 48, 183 (1986)) reported an organic photovoltaic cell with a double-layer organic thin film structure, with an energy conversion efficiency close to 1%. After nearly ten years of hard work, people have realized that the main reason limiting the further improvement of the efficiency of organic photovoltaic devices is that the exciton diffusion length of organic materials (generally no higher than 10 nm) is much smaller than the light absorption length of the material (generally around 100 nm). In 1995, the...
