Sebastian Tepner and Andreas Lorenz contributed equally to this work. This paper presents a comprehensive overview on printing technologies for metallization of solar cells. Throughout the last 30 years, flatbed screen printing has established itself as the predominant metallization process for the mass production of silicon solar cells.
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.
A successful application of this printing method for the metallization of heterojunction solar cells has been demonstrated. 369 First attempts to use rotary screen printing for the metallization of silicon solar cells date back to the late 1990s 362 but have not been pursued further.
Screen-printed solar cells were first developed in the 1970's. As such, they are the best established, most mature solar cell fabrication technology, and screen-printed solar cells currently dominate the market for terrestrial photovoltaic modules. The key advantage of screen-printing is the relative simplicity of the process.
In the photovoltaic industry, screen printing accounts for majority of the metallisation processes for silicon wafer solar cells. Contact formation by co-firing of front and rear screen printed metal pastes for mainstream p -type standard solar cells is a well-established process.
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.
