To halt the buildup of carbon dioxide (CO2), the main greenhouse gas, the development of an alternative energy source to fossil fuels becomes more and more important. Hydrogen (H2) has the potential to meet the requirements as a clean non-fossil fuel in the future, if it can be produced using our primary source of energy, the sun, and stored and transported safely. The present article will give a short review on different approaches on semiconductor-based photoelectrochemical water splitting into hydrogen and oxygen (O2) using sunlight as the energy input, also generally described as photoelectrolysis.
