Nanostructured transparent conducting oxide (TCO) layers gain increasing importance as high surface area electrodes enabling incorporation of functional redox species or electroactive coatings with high loading. I work on different strategies towards the facile fabrication of TCO electrodes with different types of porous structures and pore dimensions based on the assembly of dispersible TCO nanoparticles.[1-3] The crystallinity of the nanoparticles serving as building blocks enables the formation of fully crystalline porous transparent scaffolds with high electric conductivity. The nanostructure can be controlled using suitable templates such as amphiphilic polymers [1] or latex beads [2-3], giving access to a broad range of TCO electrodes with pore sizes between 3 nm and 300 nm. While commercial templates like Pluronic polymer or latex beads result in predetermined pore sizes, novel amphiphilic PEO-b-PHA polymers enable the fabrication of remarkably tunable TCO morphologies with nominal pore sizes from 10 nm mesopores to 80 nm macropores.[1] The combination of porous architecture with a large conducting interface makes the obtained layers versatile current collectors with adjustable performance.
