Abstract:
Many studies designate hematite as a promising material for direct water splitting into hydrogen and oxygen. For a real outdoor application, it is important to consider hourly and seasonal conditions like temperature and sunlight intensity. The performance of an undoped hematite thin-film photoanode was tested in a photoelectrochemical cell under varying conditions of temperature and light intensity. Both parameters show a positive effect on performance under outdoor conditions.
