This document discusses transparent electronics using transparent conducting oxides (TCOs). It introduces TCOs such as indium tin oxide which allow for both optical transparency and electrical conductivity. This is achieved through degenerate doping and the Burstein-Moss shift. TCOs find applications in transparent thin-film transistors, resistors, capacitors and indutors which could enable see-through laptops, phones and solar panels. Further advances could lead to solar windows but also environmental challenges.
