Abstract
Hydrogen fuel can be generated from the photoelectrochemical cell (solar fuel cell) through water splitting using solar energy. Among various photoanode materials for the solar fuel cell, cuprous oxide has many advantages such as narrow band gap (Eg = 1.9 ~ 2.2 eV), appropriate conduction band and valence band positions, high absorption coefficient in the visible spectral region, and environmentally benign nature, etc. When the light illuminates cuprous oxide, photogenerated holes in the cuprous oxide photoelectrode oxidize water to generate O₂ and photogenerated electrons reduce protons at the surface of counter electrode. The photocurrent is enhanced by increasing surface area and decreasing interfacial boundaries of cuprous oxide [1]. In this presentation, cuprous oxide electrode composed of dendritic nanosheests will be introduced Mechanism for the formation of dendritic nanosheet and its phoroelectrochemical properties will be discussed[2].
