The most common passivation materials used are a-Si:H and SiO x. The highest efficiency of the current MoO x hole-selective contact-based solar cell is achieved by using an intrinsic a-Si:H layer on both c-Si surfaces, realizing a conversion efficiency of 23.5% .
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.
We review the surface passivation of dopant-diffused crystalline silicon (c-Si) solar cells based on dielectric layers. We review several materials that provide an improved contact passivation in comparison to the implementation of dopant-diffused n+ and p+ regions.
The selectivity of the passivation contact for different types of carriers can be achieved via doping, represented by the SHJ solar cells, which use a combination of intrinsic and doped a-Si:H to achieve both full-surface passivation and carrier-selective transport.
Here, we report on the application of phosphorus-doped polysilicon passivating contacts on large-area screen-printed n-type silicon solar cells, using industrially viable fabrication processes. A champion cell efficiency of 24.79% is reported, as independently measured by ISFH-CalTeC on a 163.75 × 163.75-mm solar cell.
Interfacial passivation layers: The commonly used a-Si:H passivation layer has parasitic absorption and requires relatively expensive PECVD equipment; natural oxide passivation does not meet the requirements. SiO x passivation layers have been used in TOPCon solar cells with gratifying results.
