Abstract

The invention aims to provide a method for preparing a novel buffer layer zinc oxide-sulfur target material. The target material is mainly composed of zinc oxide, at the same time vulcanized magnesium, vulcanized zinc, and a third oxide are added, and the buffer layer carrier concentration is controlled to obtain a better PN characteristic. The preparation method of the multi-oxide target material comprises firstly-used technologies of slurry casting and mid-high temperature sintering so as to improve the target material uniformity and compactness, prolong the target material service life, increase the utilization rate of the target material, and improve the quality and performance of sputtered film. Through the formula design and improved target material quality, the conversion rate of CIGS solar battery is improved, the production cost is reduced, and the demand on batch production is fulfilled.

Description

technical field [0001] The invention relates to a method for preparing a novel target material, in particular to a method for preparing a novel buffer layer zinc oxide sulfur target material for copper indium gallium selenium photovoltaic cells. Background technique [0002] The demand for global energy is increasing year by year. With the rising awareness of energy conservation and environmental protection, the development of renewable energy is a common goal in the world. In terms of renewable energy, regardless of hydropower, wind power, and geothermal power generation, it is necessary to use kinetic energy conversion to obtain conversion efficiency. Solar power generation is a power generation system that converts sunlight into electrical energy. There are no moving parts in a solar power generation system, unlike wind power, hydraulic power, geothermal power generation systems that require rotating machinery, so there will be no high temperature, high pressure and Nois...
