Transparent Conductive Oxides: Applications and Properties

This lecture covers the applications and properties of Transparent Conductive Oxides (TCOs), which are materials that can transmit light and conduct electricity simultaneously. TCOs find applications in various optoelectronic devices such as touch screens, OLEDs, and solar cells. The lecture discusses the basic properties of TCOs, their electrical and optical characteristics, as well as their impact on device performance. It also explores the relationship between carrier density and refractive index in TCOs, the importance of antireflection coatings, and the role of TCOs in enhancing light trapping in solar cells.
