Do PERC-type solar cells need contact passivation?
Metal contacts of high-efficiency cells do thus require an effective means of contact passivation. Today's PERC-type solar cells use high doping underneath the metal contacts as a means of contact passivation. Fig. 7 shows a schematic of the band diagram and the quasi-Fermi levels in the contacted region of a PERC device.
What materials are used for passivating contact solar cells?

Why do solar cells have a high passivation efficiency?
This excellent passivation performance can be attributed to improved interfacial hydrogen chemical passivation and the field-effect passivation induced by the highly Al-doped ZnO film. Demonstrated n-type c-Si solar cells using full-area SiO x /AZO rear contacts achieved a significant efficiency of 23.17%.
Is there an alternative passivating contact for solar cells?
Here, we report an alternative passivating contact that is formed in a single post-deposition annealing step called ‘firing’, an essential step for current solar cell manufacturing. As firing is a fast (<10 s) and high-temperature (>750 °C) anneal, the required microstructural and electrical properties of the passivating contact are stringent.
