With continuously growing energy demands, new alternative energy solutions become essential. In order to achieve sustainability, efficient conversion and storage of solar energy are imperative [1<\/a>]<\/sup> [2<\/a>]<\/sup>. Photoelectrolysis utilizes solar energy to evolve hydrogen and oxygen from water, thereby enabling energy storage via chemical means. This work investigates photoelectrodes that offer high conversion efficiency, long-term stability, and low cost. The focus is initially on semiconducting metal oxides in which the energy band, defect, and micro-structure are tuned to optimize optical absorption, charge transport, and reduced overpotentials. For high efficiency, a cobalt-based oxidation catalyst [3<\/a>]<\/sup> is implemented at the photoelectrode. The electro-deposition kinetics of this catalyst are studied as part of this project to allow further insights into the catalytic mechanism.<\/p>\n
