Abstract

The invention discloses a transparent conductive film with enhanced thermal stability and an application thereof, belonging to the field of photoelectric devices. The transparent conductive film with enhanced thermal stability provided by the invention successively comprises a substrate, a first oxide layer, a first heavily doped layer, a metal layer, a second heavily doped layer and a second oxide layer from bottom to top. The invention also provides an application of the transparent conductive film in photoelectric devices. The resistivity of the transparent conductive film is reduced by introducing heavily doped layers between the metal layer and the oxide layers of the transparent conductive film, and the thermal stability of the transparent conductive film is improved.

Description

technical field [0001] The invention belongs to the field of optoelectronic devices, and in particular relates to a transparent conductive film with enhanced thermal stability and its application in optoelectronic devices. Background technique [0002] Transparent conductive oxides (TCO) represented by tin-doped indium oxide (ITO), fluorine-doped tin oxide (FTO) and aluminum-doped zinc oxide (AZO) films usually have a band gap, high light transmittance in the visible spectrum, and resistivity. Low common optoelectronic properties are widely used in solar cells, flat panel displays, special functional window coatings and other optoelectronic devices. In recent years, oxide-metal-oxide (ie OMO, such as ITO|Ag|ITO, ZnO|Ag|ZnO, AZO|Ag|AZO, NiO|Ag|NiO, SnO 2 |Ag|SnO 2 etc.) Transparent conductive films have been extensively studied and gradually applied to optoelectronic fields such as solar cells and displays. In practical applications, transparent conductive films not only r...
