Thin-film solar cells are a type of made by depositing one or more thin layers ( or TFs) of material onto a substrate, such as glass, plastic or metal. Thin-film solar cells are typically a few nanometers () to a few microns () thick–much thinner than the used in conventional (c-Si) based solar cells, which can be up to 200 μm thick. Thin-film solar cells are commercially used in several technologies, including (.

Substations themselves do not usually have generators, although a power plant may have a substation nearby. Other devices such as capacitors, voltage regulators, and reactors may also be located at a substation.OverviewA substation is a part of an electrical , , and system. Substations transform from high to low, or the reverse, or perform any of several other important functions. Between th. .
Substations may be designed and built by a or alternately all phases of its development may be handled by the . Most commonly, the utility does the engineering and procurement while hirin. .
Substations typically serve at least one of the following purposes: • Increasing the voltage produced by for efficient over long distances, using step-up transformers .
