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.
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.
These activities gathered a new momentum in the early 2010 years, when several research groups presented promising results of feasibility studies using flexographic printing, 370 - 372 rotary screen printing, 373 and gravure printing 369 for solar cell metallization.
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 industrial standard method to generate the surface texture is wet-chemical etching. While the texture is beneficial for the optical performance of the solar cell, the increased roughness of the surface is disadvantageous with respect to fine-line front side metallization using printing techniques.
Drawbacks with the conventional solar cell manufacturing systems, solar cell development challenges, and future prospects are also highlighted. The paper concludes that 3D printing technology can be a viable candidate to fabricate solution-processable solar cells over a wide area with excellent material utilization and good flexibility.
