Abstract

A vanadium-based lead-free glass powder and its preparation method and application, which relate to a glass powder and its preparation method and application. The purpose of the present invention is to solve the high glass transition temperature and large particle size of the glass frit used in the existing preparation of lead-free paste, the price of lead-free paste is expensive, it is not conducive to large-scale production, and the existing paste is used The problem of low conversion efficiency of solar cells. Vanadium-based lead-free glass powder is composed of V 2 o 5 、 Bi 2 o 3 ,P 2 o 5 , B 2 o 3 , SiO 2 、Na 2 O, Cu 2 O, ZnO, Al 2 o 3 、TiO 2 , Sb 2 o 3 , Li 2 O and Ag 2 O prepared. Methods: 1. Weighing; 2. Mixing; 3. Melting; 4. Quenching; 5. Grading. Vanadium-based lead-free glass powder is used to prepare front silver paste for crystalline silicon solar cells. The invention can obtain a vanadium-based lead-free glass powder.

Description

technical field [0001] The invention relates to a glass powder and its preparation method and application. Background technique [0002] With the increasing global energy demand, global warming and environmental pollution, countries are increasingly looking for alternative energy sources. Because solar energy is the only inexhaustible energy source in the world. People are beginning to turn their attention to clean and renewable energy sources such as solar energy. Lead-free crystalline silicon solar cells are one of the main ways of solar energy applications. Under the action of light, the crystalline silicon solar cell converts solar energy into electrical energy through silver grid lines, and the surface electrodes and silver grid lines are made of conductive silver paste. However, the conductive paste used in traditional crystalline silicon solar cells contains lead paste, which pollutes the environment during the production process. At the same time, the glass powder...
