Photo-assisted electrolysis cell with p-silicon and n-silicon electrodes
MetadataShow full item record
The photoelectrolysis of water by solar radiation to produce hydrogen and oxygen is achieved using semiconductor electrodes. The cell comprises a p-silicon wafer treated with catalyst as photocathode and metal doped n-silicon wafer as photoanode. The cell is operated at a small bias potential.
