In addition, at lower voltages where the effective resistance of the solar cell is high, the impact of a resistance in parallel is large. A silicon oxide film is well known to be a good candidate for a passivation film in a solar cell because it can be used as an insulating film for the PID phenomenon and lower the recombination velocity.

No 43 Bailing South Road, Quzhou Green Industry Clustering Zone, Quzhou, Zhejiang 324022, China Passivation technology is crucial for reducing interface defects and impacting the performance of crystalline silicon (c-Si) solar cells. Concurrently, maintaining a thin passivation layer is essential for ensuring efficient carrier transport.
Surface passivating thin films are crucial for limiting the electrical losses during charge carrier collection in silicon photovoltaic devices. Certain dielectric coatings of more than 10 nm provide excellent surface passivation, and ultra-thin (<2 nm) dielectric layers can serve as interlayers in passivating contacts.
This study employs a dual-layer intrinsic amorphous silicon passivation layer, supplemented with intermediate hydrogen plasma treatment (HPT), which enhances the passivation effectiveness and simultaneously augments the fill factor (FF) of the solar cell.
Concurrently, maintaining a thin passivation layer is essential for ensuring efficient carrier transport. With an ultrathin passivated contact structure, both Silicon Heterojunction (SHJ) cells and Tunnel Oxide Passivated Contact (TOPCon) solar cells achieve an efficiency surpassing 26%.
