WebOur results show that the deposition of doped layers on intrinsic amorphous silicon supplies additional hydrogen to the amorphous/crystalline heterostructure. Moreover, the deposition of a p-layer modifies the microstructure of the intrinsic layer underneath, whereas depositing an n-layer does not induce structural changes.

WebThis process may be similar to Step 603 in FIG. 6. If Layer 1 is a hole transport layer rather than an electron transport layer, Layer 1 could be a metal oxide like MoOx or multiple layers like intrinsic and doped amorphous silicon or SiCh and doped poly silicon. In Step 702, a transparent conductor (Layer 2) is deposited.

Used as semiconductor material for a-Si solar cells, or thin-film silicon solar cells, it is deposited in thin films onto a variety of flexible substrates, such as glass, metal and plastic. Amorphous silicon … See more Silicon is a fourfold coordinated atom that is normally tetrahedrally bonded to four neighboring silicon atoms. In crystalline silicon (c-Si) this tetrahedral structure continues over a large range, thus forming a well-ordered … See more The density of amorphous Si has been calculated as 4.90×10 atom/cm (2.285 g/cm ) at 300 K. This was done using thin (5 micron) strips of … See more While a-Si suffers from lower electronic performance compared to c-Si, it is much more flexible in its applications.
