Praia Silicon Solar Cell Classification

Are c-Si solar cells based on doped polycrystalline silicon/SIO 2 junctions?

This perspective focuses on one stream of future c-Si solar cells incorporating passivated contacts based on doped polycrystalline silicon/SiO 2 junctions, commonly called poly-Si junctions.

Are poly-Si junctions the next evolutionary step for silicon solar cells?

Silicon solar cell architectures featuring poly-Si based junctions are poised to become the next evolutionary step for mainstream silicon PVs, paving the way toward an average industry cell efficiency of 25% over the next decade.

Are c-Si solar cells a good choice for terrestrial photovoltaics?

After 40 years, crystalline silicon (c-Si) solar cells remain the clear leaders of the terrestrial photovoltaic market. This position is largely due to continual adjustments of the c-Si cell architecture, which have provided steady efficiency gains, together with drastic cost reductions brought about by large-scale manufacturing.

Which solar cells are certified by Caltec/ISFH?

TABLE 3b. Silicon solar cells with metal compounds/organics as hole contacts a Certified by CalTeC/ISFH. b With a pitch length of 920 μm). TABLE 3c. Both sides contacted and IBC silicon solar cells with metal compounds as both electron and hole contacts

What is a SHJ solar cell?

SHJ solar cells were the first reported high efficiency crystalline silicon cell structures using a wider bandgap “passivating contact.” In particular, this structure employed stacks of intrinsic and doped hydrogenated amorphous silicon (a-Si:H) layers, for both contacts of the solar cell.

How are solar cells classified?

Because of that, we classify the solar cells in this section according to the functionality of the contact, either as electron-selective (Table 3a) or as hole-selective (Table 3b), with a third group dedicated to devices where both selective contacts are made with metal compounds (Table 3c).
