Transparent conductive films are an important part of many optoelectronic devices, such as flat panel displays, organic solar cells, organic light emitting diodes (OLEDs), smart windows, and the like. Indium tin oxide (ITO) has become the main material of transparent conductive films due to its high electrical conductivity and light transmittance. However, ITO also has some disadvantages, such as ...
