Abstract

The invention relates to a supermolecule type organic solar battery material and a preparation method thereof, and provides a new way for enhancing energy conversion efficiency. The supermolecule type organic solar battery material contains four basic structural units, namely a donor unit, a receptor unit, a connection unit and a self-assembly unit, wherein the connection unit and the self-assembly unit are different molecule structures or same molecule structures; the donor unit is one of thiofuran, phenylacetylene, diphenyl, aromatic amine, and a condensed nucleus aromatic compound or phthalocyanine or is one of derivants of the thiofuran, the phenylacetylene, the diphenyl, the aromatic amine and the condensed nucleus aromatic compound or the phthalocyanine; the receptor unit is one of fullerene and perylene or a carbon nano tube or is one of derivants of the fullerene and the perylene or the carbon nano tube; the selection of the connection unit is split into two types according to an energy level matching condition: a. an insulation type connection unit which prevents the movement of electrons and holes; and b. a connection type connection unit which is good for the transfer of the electrons when a receptor is excited, good for the transfer of the holes when a donor is excited and good for the transfer of the electrons and the holes when a connection group is excited.

Description

technical field [0001] The invention relates to a supramolecular organic solar battery material and a preparation method thereof. Especially material molecules composed of donors, acceptors, linking groups and assembly groups through different connection methods. Background technique [0002] The efficient use of solar energy technology is currently a research hotspot and difficulty worldwide. As a forward-looking and strategic new energy technology that supports my country's national economy and sustainable development, it has been listed as a key support and priority development direction in the national medium and long-term scientific and technological development plan. The silicon and GaAs series solar cells based on inorganic semiconductors that have entered the civilian market currently have problems such as expensive raw materials, complicated preparation processes, large quality, fragility, high energy consumption and high waste emissions, which limit their further ...
