Recent Research of Cu-based Transparent Conducting Materials with p-type

Cu-based transparent conducting materials (TCMs) have many special properties, so they can be used in many application fields such as panel display, transparent transistor, and solar photovoltaic energy systems. In this paper, the recent achievements on the TCMs of some Cu-based oxides and oxysulfides are reviewed, which are focused on the structure chemistry and conducting mechanism, considering the strong correlation between structure and performance. It is pointed out that conducting [Cu2S2] layers are quite common and important for p-type conducting, and the layered-structure will promise a wide band gap for the materials.
