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.
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.
The key advantage of screen-printing is the relative simplicity of the process. There are a variety of processes for manufacturing screen-printed solar cells. The production technique given in the animation below is one of the simplest techniques and has since been improved upon by many manufacturers and research laboratories.
Screen-printed solar cells typically use a simple homogeneous diffusion to form the emitter where the doping is the same beneath the metal contacts and between the fingers. To maintain low contact resistance, a high surface concentration of phosphorus is required below the screen-printed contact.
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.

Recent technology development of crystalline silicon solar cell is proceeding to reduce the manufacturing cost while improving the efficiency. Therefore, screen printing requires process development to reduce a line width of an electrode and decrease shading area.
Flatbed screen printing is the dominating process in industry for metallization of silicon solar cells. It offers high throughput rates, high flexibility of printing pattern, and an overall very cost-effective production compared with other printing technologies.
With focus on the screen printing process, realizing fine line grids on the front—and in case of bifacial solar cells on the rear—side is particularly challenging. The front side metallization of a solar cell has to combine an optimal trade-off between shading of the metal grid (finger shape and width, and number of contact fingers), series ...
