A layer of semiconductor material, such as copper indium diselenide, cadmium telluride, gallium arsenide, or amorphous silicon, a few microns or less in thickness, used to make photovoltaic cells. Commonly called amorphous.
Electronics. Any of several thin layers (generally less than 1 m each) of insulating, conducting, or semiconductor material that are deposited successively on a supporting substrate in precise patterns to collectively form all or part of an integrated circuit; the deposition can be performed by mechanical, chemical, or high-vacuum evaporation methods.
A thin film (usually less than 5 mm thickness) is one that is deposited onto a substrate by an accretion process such as vacuum evaporation, sputtering, chemical vapour deposition, or pyrolytic decomposition.
PV – A solar-electric technology utilizing very thin layers of semiconductor materials, usually one to 10 microns. This type of device uses far less material than a conventional silicon photovoltaic (PV) panel.
A solar PV module constructed with sequential layers of thin film semiconductor materials usually only micrometers thick. Currently, thin-film technologies account for around 12 percent of all solar modules sold worldwide. This share is expected to increase, since thin-film technologies represent a potential route to lower costs. Commonly called amorphous.
Thin films are material layers of about 1 Âµm thickness. Electronic semiconductor devices and optical coatings are the main applications benefiting from thin film construction. Some work is being done with ferromagnetic thin films as well for use as computer memory.
