6 FAQs about [Thickness of amorphous silicon solar cells]

What are amorphous silicon solar cells?

Amorphous silicon solar cells are commercially available and can be produced on a variety of substrates ranging from glass to flexible thin foils. Cells are built in p-i-n or n-i-p configurations, where p and n represent thin doped (amorphous or nanocrystalline) layers, and the absorber layer is an intrinsic undoped layer.

What are amorphous silicon thin films used for?

Amorphous silicon (a-Si:H) thin films are currently widely used as passivation layers for crystalline silicon solar cells, leading, thus, to heterojunction cells (HJT cells), as described in Chap. 7, next-up. HJT cells work with passivated contacts on both sides.

How efficient are amorphous solar cells?

The overall efficiency of this new type of solar cell was 7.1–7.9% (under simulated solar light), which is comparable to that of amorphous silicon solar cells .

Do amorphous silicon-based solar cells lose efficiency?

Amorphous silicon-based solar cells exhibit a significant decline in their efficiency during their first few hundred hours of illumination; however, the degradation of multiple layer solar cells and of nanocrystalline silicon cells is much lower.

Can amorphous silicon solar cells be fabricated in a stacked structure?

Amorphous silicon solar cells can be fabricated in a stacked structure to form multijunction solar cells. This strategy is particularly successful for amorphous materials, both because there is no need for lattice matching, as is required for crystalline heterojunctions, and also because the band gap is readily adjusted by alloying.

Do amorphous silicon solar cells need light-trapping?

Amorphous silicon (a-Si:H) solar cells have to be kept extremely thin (thickness below 0.2 μm), so as to maximize the internal electric field Eint, and, thus, allow for satisfactory collection of the photo-generated electrons and holes. Therefore, light-trapping is absolutely essential for a-Si:H cells.
