Title: | Interface and catalyst investigation for solar water splitting | ||||
Language: | English | ||||
Abstract: | In this thesis model experiments for a photoelectrochemical water splitting device were performed. The goal was to identify loss mechanisms that reduce the efficiency of the photoelectrochemical device. This includes losses associated with solid state contacts, i.e. charge transfer into the protection layer and catalyst particles, as well as overvoltage losses encountered during catalysis. Additionally, fundamental photoelectron spectroscopy measurements revealed the complicated nature of small supported catalyst particles. Here, a direct dependence of their electronic structure with respect to their substrate material and deposition techniques was identified. Furthermore, subsequent water adsorption also changes the energetic alignment between support and catalyst. |
