Abstract The state‐of‐the‐art of research on artificial photosynthesis is briefly reviewed. Insights into how Nature takes electrons from water, the photon‐flux density of sunlight, the time scale for the arrival of the next photon (electron–hole) at the oxygen‐evolving complex, how Nature solves the photon‐flux‐density problem, and how we can get through the bottleneck of water oxidation are discussed. An alternate route for a two‐electron process induced by one‐photon excitation is postulated for getting through the bottleneck of water oxidation.
