Bifunctional photoelectrode by bilateral fabrication of photovoltaics and electrocatalyst |
| 초록 |
A photoelectrode for solar-chemical production system was constructed by Cu(InxGa1-x)(SySe1-y)2 (CIGS) thin film. Particularly, low cost solution process was applied to synthesize CIGS thin films which were also tried to be fabricated on low cost and earth abundant material substrate, stainless steel (SS). Since the SS can act as an electrocatalyst for oxygen evolution reaction (OER) the CIGS on SS would have bifunctionality of photo-charge generation and overpotential reduction for water oxidation. To prepare highly efficient bifunctional CIGS photoelectrode the electrocatalytic properties of SS were investigated with respect to the individual process for the CIGS film synthesis. We found that the harsh oxidation of SS resulted in the formation of OER active-surface structure of NiOOH. These results imply the possibility of bilateral synthesis of the efficient photoelectrode composed of CIGS and OER catalyst in a single substrate. The details will be discussed in the presentation. |
