Problems solved by technology

At present, the commonly used counter electrode of DSCs is the noble metal platinum (Pt) electrode. However, the Pt electrode obtained by pyrolyzing chloroplatinic acid at 450 °C has a low transmittance in the visible light region (<55%), and the Pt material is expensive, resulting in Counter electrode manufacturing costs account for more than 60% of the entire battery

Abstract

The invention provides a non-platinum-based transparent electrode material, a preparation method and application thereof, and belongs to the technical field of solar cells. The non-platinum-based transparent electrode material comprises an FTO substrate, a molybdenum-based transparent conductive carrier film located on the surface of the FTO substrate and a non-platinum transition metal located onthe surface of the molybdenum-based transparent conductive carrier film, wherein the particle size of the non-platinum transition metal is less than or equal to 5 nm, and the thickness of the molybdenum-based transparent conductive carrier film is 5-30 nm. According to the non-platinum-based transparent electrode material provided by the invention, FTO is used as a substrate, so that the transparency is high; the molybdenum-based transparent conductive carrier film is good in uniformity and permeability, so that the dispersion uniformity of non-platinum transition metal can be improved; the non-platinum transition metal is small in particle size and large in specific surface area, so that high catalytic activity of the non-platinum-based transparent electrode material is guaranteed; and the non-platinum-based transparent electrode material provided by the invention is high in transmittance, and can meet the requirements of laminated and double-sided irradiation and transparent photoelectric devices on electrodes.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a non-platinum-based transparent electrode material and a preparation method and application thereof. Background technique [0002] The appearance of dye-sensitized solar cells (DSCs) is rich in color, high in transparency, and its efficiency is less affected by incident light, so that it shows broad market application prospects in stacking, double-sided irradiation, and transparent optoelectronic devices. The counter electrode can promote electrolyte reduction and is an important part of DSCs. With the continuous development of science and technology, higher requirements are put forward for the counter electrode of DSCs. For example, the counter electrode needs to meet the requirements of high conductivity, high catalytic activity, high transparency, easy preparation, and low cost. At present, the commonly used counter electrode of DSCs is the noble metal platinum (Pt) elec...
