| Abstract |
Solar-fuel production inspired from nature has attracted substantial attention due to a need for developing sustainable future energy as well as chemical resources. In this study, we demonstrated a highly efficient solar energy to chemical conversion device using CO2 and water as feedstock. For the realization of this architecture we developed a thin film photovoltaic technology for the light absorbing component using a low cost, solution based Cu(InxGa1-x)(SySe1-y)2 (CIGS) fabrication method to provide high enough potential for the conversion reactions. This CIGS technology was also applied to photocathode fabrication for direct reduction of proton or CO2 in aqueous phase. The details of the synthetic method and characterization of each component and the solar-fuel production system will be discussed in the presentation. |
