Photoelectrochemical Energy Materials and Device
|
강순형 교수 전남대학교 The increasing energy demand and environmental pollution are today’s most important problems and the scientific community is searching a new form of energy alternative to fossil fuels which is one of the primary research topics of the 21st century. Hydrogen is the fuel of the future because of high gravimetric energy density and clean combustion. Hydrogen can be produced by photoelectrochemical(PEC) water splitting method by using semiconductor photoanode/photocathode. The efficient, stable, visible light absorption and cost effective photoelectrode materials are certainly important in developing highly efficient PEC system. Here, we discussed the related energy materials including the oxides and nitrides for the PEC water splitting and further, the electrochemical CO2 reduction would be shortly discussed using the Cu-electrocatalyts. In particular, to enhance the light harvesting efficiency as well as charge collection efficiency, a variety of tools such as the doping, composite, heterojunction, nanostructuring and so on would be suggested. In addition, the functionality of materials combination would proposed for the PEC application to improved the performance. The detail discussion would be done in the presentation. |
