Transfer of Preformed Three‐Dimensional Photonic Crystals onto Dye‐Sensitized Solar Cells

Film star: Preformed self-assembled 3D photonic crystals (see picture) can be infilled with a polycarbonate matrix for mechanical stability and transferred onto rough and porous optoelectronic and photovoltaic devices. This technique allows the incorporation of photonic crystals onto independently processed devices, in which the transferred films have high optical quality.
