Development of artificial photosynthesis is prospected on the basis of its history, the three milestones in late 20th century, and recent advances in biological approach, molecular catalysts, and semiconductors chemistry. Photon-flux-density problem to be resolved in getting through one of the bottleneck issues is discussed as well as renewable energy factor (REF) as one of the most crucial points to be considered even in the early stage of fundamental research.
