Photolysis of Water as a Solar Energy Conversion Process: An Assessment

  • S. N. Paleocrassas


One of the less conventional solar energy conversion methods is the photocatalytic decomposition of H2O to generate H2 and O2 directly. This paper presents an assessment of photolysis of water by sunlight. Calculations are used to establish efficiency upper limits for this type of energy conversion method using three differeng photocatalysts: compound salts, compound semiconductors, and photosynthetic dyes. The efficiencies were estimated to be 3 percent, 28 percent, and 7 percent, respectively.
