Silicon material having no definite or regular crystal structure; the semi-conducting material in a-Si active matrices
A semiconductor film used as the active layer in most active matrix liquid crystal displays (LCDs). It is based upon the electronic properties of a glass alloy of silicon and hydrogen.
A form of silicon that is noncrystalline. Also called thin film, it is different from regular silicon used in panels and chips, in that it is more flexible. It can be deposited in thin (measured in micrometers) layers by a number of methods.
A semiconductor material that is used to make the thin film transistors (TFTs) layer of an active matrix LCD.
A type of silicon deposited on a variety of surfaces (rigid and flexible) with thin homogenous layers. Amorphous silicon absorbs light more effectively than crystalline silicon, so the cells can be thinner. For this reason, amorphous silicon is also known as a "thin film" photovoltaic technology.
"Sometimes abbreviated as ""a-Si"", amorphous silicon is used as a disordered semi-conductor material in the plasma-enhanced chemical vapor deposition (PECVD) process used to create thin-film solar cells on a stainless-steel substrate"
A thin-film PV silicon cell having no crystalline structure. Manufactured by depositing layers of doped silicon on a substrate.
An alloy of silica and hydrogen, with a disordered, noncrystalline internal atomic arrangement, that can be deposited in thin-layers (a few micrometers in thickness) by a number of deposition methods to produce thin-film photovoltaic cells on glass, metal, or plastic substrates.
Amorphous silicon (a-Si) is the non-crystalline allotropic form of silicon. Silicon is a four-fold coordinated atom that is normally tetrahedrally bonded to four neighboring silicon atoms. In crystalline silicon this tetrahedral structure is continued over a large range, forming a well-ordered lattice (crystal).
