Historically, electrochemical passivation had been shown to increase the PCE of interdigitated back contact (IBC) solar cells and a PSS thin film was employed in IBC solar cells as a front surface passivation layer.
Recombination is one of the major reasons that limit solar cell efficiency. As a remedy, passivation reduces recombination both at the surface and the bulk. The field-effect passivation mitigates the surface recombination by the electric field generated by the excess doping layer or by the corona charging of the dielectric layer.

For the high-performance C/Si HJ solar cells, the CNT/Si interface passivation is highly desirable. As mentioned above, a passivation method should have a high passivation effect and can be deposited into CNT/Si interface as well as can integrate into CNT to be one material.
This phenomenon reduces the interface defect states and suppresses minority carrier recombination and thus increases VOC and PCE of the hybrid solar cells. Further research revealed that the origin of the organic passivation is the sulfonic acid group on the PSS molecule.
