| Outline of Final Research Achievements |
In the research project “Development of NIR light responsible photoelectrodes for water splitting”, photoelectrochemical materials with long absorption edge were investigated.
CuInSe2 showed considerably long absorption edge of over 1200 nm with significantly high onset potential of 0.7 V vs. RHE in hydrogen evolution from water.
In addition, we developed solid solution of ZnSe and Cu(In,Ga)Se2 (ZnSe:CIGS) as a photocathode material. ZnSe:CIGS was found to be the promising material for hydrogen evolution from water under sunlight. Because, the photocathode composed of the solid solution showed high onset potential of 0.9 V vs. RHE and long absorption edge on about 900 nm.
