Abstract (en)
[origin: WO2011107549A2] The invention relates to a transparent conductive substrate for optoelectronic devices, comprising a base and a conductive coating comprising doped zinc oxide, said coating being formed by a stack of at least two layers having different electrical conductivity, namely a so-called high conductivity layer and a so-called low conductivity layer. According to the invention, the high conductivity layer is a layer comprising zinc oxide doped with m wt.-% of oxide of a doping element where m is less than or equal to 6 and the so-called low conductivity layer is a layer comprising zinc oxide doped with (m/p) wt.-% of oxide of a doping element where p is greater than or equal to 2.
