摘要: Entropy and unavoidable irreversibility place a limit on the efficiency of photochemical solar energy conversion which is substantially lower than that placed by first law thermodynamics alone. Shockley Queisser’s ’’detailed balance limit’’ p‐n‐junction photovoltaic devices special case this general thermodynamic all quantum‐utilizing converters. For single system operating at 20 °C in sunlight not attenuated atmosphere, cannot exceed 29%. Under same conditions, converter composed two systems can reach 41%.
