Thin-film solar cells, a second generation of photovoltaic (PV) solar cells: Top: thin-film silicon laminates being installed onto a roof. Middle: CIGS solar cell on a flexible plastic backing and rigid CdTe panels mounted on a supporting structure Bottom: thin-film laminates on rooftops Thin-film solar cells are a type of solar cell made by depositing one or more thin layers (thin films or ...
Thin-film optics is the branch of optics that deals with very thin structured layers of different materials. [1] In order to exhibit thin-film optics, the thickness of the layers of material must be similar to the coherence length; for visible light it is most often observed between 200 and 1000 nm of thickness.
Cadmium telluride photovoltaics. PV array made of cadmium telluride (CdTe) solar panels. Cadmium telluride (CdTe) photovoltaics is a photovoltaic (PV) technology based on the use of cadmium telluride in a thin semiconductor layer designed to absorb and convert sunlight into electricity. [1] Cadmium telluride PV is the only thin film technology ...
A thin film is a layer of material ranging from fractions of a nanometer (monolayer) to several micrometers in thickness. [ 1 ] The controlled synthesis of materials as thin films (a process referred to as deposition) is a fundamental step in many applications. A familiar example is the household mirror, which typically has a thin metal coating ...
A thin-film transistor (TFT) is a special type of field-effect transistor (FET) where the transistor is made by thin film deposition. TFTs are grown on a supporting (but non-conducting) substrate, such as glass. This differs from the conventional bulk metal oxide field effect transistor (MOSFET), where the semiconductor material typically is ...
A copper indium gallium selenide solar cell (or CIGS cell, sometimes CI (G)S or CIS cell) is a thin-film solar cell used to convert sunlight into electric power. It is manufactured by depositing a thin layer of copper indium gallium selenide solid solution on glass or plastic backing, along with electrodes on the front and back to collect current.
Photolithography is a subclass of microlithography, the general term for processes that generate patterned thin films. Other technologies in this broader class include the use of steerable electron beams , or more rarely, nanoimprinting , interference , magnetic fields , or scanning probes .
Thin-film deposition is a process applied in the semiconductor industry to grow electronic materials, in the aerospace industry to form thermal and chemical barrier coatings to protect surfaces against corrosive environments, in optics to impart the desired reflective and transmissive properties to a substrate and elsewhere in industry to modify surfaces to have a variety of desired properties.
