This is a horizontally mounted, double-tank cell typically used for anodization of Si-wafers with electrolyte backside contact. It consists of two polyether ether ketone (PEEK) gas-tight chambers each equipped with sapphire wafer serving as window for illumination allowing light-assisted porous Si formation. It well fits aqueous (FKM/EPDM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. The Si substrate is mounted in between these chambers and sealed with O-rings under magnetic mount (a screw version is available on request). The preparation of a whole porous Si substrate with this cell is possible at one simple etching step, assuring high reproducibility.
