Preparation of squaraine dye-sensitized nanocrystalline film electrode

Abstract

The invention designs and combines a squaraine dye with excellent performance, which is used in a dye-sensitized solar battery to obtain good performance test result of a photocell. An asymmetrical squaraine dye sensitizer used by the invention is compounded by adopting a fractional step method, the designed molecules are reasonable, and the molecule has high light stability. The compounded target product contains less by products, and is easy to separate and purify. All the designed squaraine dye molecules contain carboxyl, can form adsorption with the surface of a nanocrystalline film electrode, and have good application prospect in the photoelectric material field or the biomolecules detection field.

Description

technical field

[0001] The invention belongs to the field of solar cell high-tech materials. Background technique

[0002] In recent years, with the intensification of the energy crisis, the development of new energy has become the focus of research in various countries. Solar energy is a renewable energy source, and solar photovoltaic cells, as a device that converts light energy into electrical energy, have emerged as the times require. A solar cell is a device that converts solar energy into electrical energy. However, the monocrystalline silicon and polycrystalline silicon solar cells that have been industrialized are not conducive to large-scale use because of their high cost and easy corrosion by light. Organic dye-sensitized solar cells have the advantages of low cost, simple manufacturing process, and not easy to be corroded, and have attracted extensive attention from research institutions in various countries. Organic dye-sensitized solar cells have many requireme...
