Transparent Conducting Oxides

AP CVD has been widely used for the deposition of TCO for an extensive range of applications

Applications include energy efficient windows (see separate page for more details), anti-static films, heatable coatings (for example as used in defrost and anti mist windows).

One growing area of exploitation is in Photovoltaics. In this application the layer is used to collect current from the PV cells (and thus needs high conductivity) but must also have high transparency to avoid light energy loses.

APCVD is successfully used for Industrial scale production of coated glasses as substrates for subsequent PV layer growth. It has also been used for coating on metal foils for the same subsequent processing. CVD Technologies technology has licensed it's technology for this application to a number of companies.

Such coating technology can be exploited either on-line (e.g. on the glass production line, or on metal roll to roll processing) or off line on glass plates or silicon wafers.
