Problems solved by technology

Under this process flow, the electrodes of all cells are finalized before the cells leave the factory, and cannot be changed in the use of subsequent photovoltaic modules; in addition, with the development of shingled technology, the layout of shingled cells is very different from that of conventional cells. General purpose, but conventional batteries are the mainstream in the market. The circulation of shingled batteries is very small, and the cost of customization is high. How to use conventional batteries to make shingled modules has become a difficult problem in the development of shingled

Abstract

The invention discloses a process method for manufacturing post-manufactured electrodes of a photovoltaic cell. According to the technical schemes, through six procedures of battery sheet cleaning, battery sheet drying, conductive ink temperature returning, conductive ink uniform shaking, conductive ink printing and low-temperature sintering, the electrodes are reconstructed through conductive inkprinting; conventional battery sheets are manufactured into an imbricate assembly, so that cost is saved, and meanwhile development of the imbricate technology is promoted.

Description

technical field [0001] The invention relates to the field of new energy solar cells, more specifically, it relates to a process method for making electrodes after photovoltaic cells. Background technique [0002] Photovoltaic technology has gradually matured after years of development, and a fixed process mode has been formed. The main conventional processes are: 1. Silicon wafer cleaning; 2. Texturing; 3. Diffusion; 4. Etching; PECVD; 7. Screen printing; 8. Sintering; 9. Test sorting. Under this process flow, the electrodes of all cells are finalized before the cells leave the factory, and cannot be changed in the use of subsequent photovoltaic modules; in addition, with the development of shingled technology, the layout of shingled cells is very different from that of conventional cells. General purpose, but conventional batteries are the mainstream in the market. The circulation of shingled batteries is very small, and the cost of customization is high. How to use conven...
