The manufacturing technique of solar cell is important for the electrical performance of solar cells. This work aims to gain additional knowledge about the influence of screen-printing technology, sintering temperature and belt speed of sintering furnace on electrical properties of the solar cells.
When the cell is cofired (in the next production step), the paste etches through the silicon nitride and silver contacts the underlying silicon to form the n -type contacts to the solar cell. This tutorial focuses on the silver screen printing process as the design of the screens is critical for the way the pattern is used to form the metal grid.
Beside screen printing, multi-nozzle dispensing, and rotary printing, further printing and coating technologies to apply the front and/or rear side metallization of silicon solar cells have been investigated in the last decades. Several studies investigated the application of the front side grid using inkjet technology.
The screen printing and rapid thermal processing [ 5 ], is a key process step in the fabrication of crystalline Si solar cells. In addition, the optical and electrical properties of the solar cells strongly depends upon the quality of the silkscreen, sintering temperature and belt speed, etc.
