The basic concepts of light‐driven water splitting using semiconductor‐based photoelectrochemical devices are reviewed with the emphasis on the prospects of achieving solar to hydrogen (STH) efficiencies that will enable the development of competitive hydrogen generation technologies to begin to replace those based on fossil fuels. Examples of the calculation of conversion efficiencies are given for different approaches to solar photoelectrolysis, illustrating the need to use well‐defined figures of merit in all publications dealing with the photoelectrochemical generation of solar fuels.
