Conclusion In the present work, design rules to employ different plating approaches as metallization technology for different types of crystalline silicon solar cells have been discussed. After many years of experience, many of the formerly problematic phenomena can now be well controlled.
The plating step can be done either with the irradiation of the front side of the cell by LIP in case of p- type cells or without light irradiation (FBP forward bias plating) in case of n-type solar cells for single sided processing. 92 G. Cimiotti et al. / Energy Procedia 67 ( 2015 ) 84 – 92 6.
Moreover, we test plating/deplating sequence instead of a direct current plating or the SiO2 layer approach to solve undesired plating outside the designed contact openings. The main objective of this paper is to explore the physical limit of this contact formation technology keeping the process compatible with industrial needs.
For plating on paste it is recommended that using plating electrolytes with pH>2 result in a good adhesion of the seed layer on the silicon surface. Further the glass content in the silver paste and the size of the glass particles have a big influence on the adhesion.
