Abstract

The field of active devices has recently shown a great interest in p-type transparent conducting oxides (TCOs). In the realm of optoelectronics, a new generation known as "Invisible Electronics" began with the introduction of transparent junctional devices. In recent years, many different p-type transparent conducting oxide materials with enhanced optical and electrical properties have been produced. These p-TCOs are not stoichiometric and are doped with suitable counter-cations/anions. For p-TCOs, chromium (Cr)-based materials stand out as the best option among all previously employed p-type materials. Despite their electrical properties lie on the insulator side, appropriate doping has been shown to greatly increase their electrical conductivity. In this review, an up-to-date and detailed explanation of TCO materials based on chromium (Cr) is provided. The development of highly efficient p-TCO films could lead in an innovative era in the form of “Transparent Electronics”, as it could pave the way for the fabrication of transparent active devices.
