Research Progress of the thermodynamic Analysis of Photosynthesis

The thermodynamic analysis of photosynthesis efficiency is critical to understand the photosynthesis mechanism, and also an important approach to achieve artificial photosynthesis with high efficiency. In this review, research progresses in the thermodynamic energy balance, entropy and exergy analysis of photosynthesis processes are discussed with particular focus on the models and development of exergy efficiency calculations. Existing literature suggests that the low photosynthesis efficiency (3.9%) of chloroplasts is attributed to two major factors, namely, the energy assumption of water evaporation, and the limited chloroplast adsorption of visible light. The maximum theoretical photosynthesis exergy efficiency of microalgae could reach up to about 13%, simply because the absence of water evaporation process. Lastly, the latest progress of artificial photosynthesis is also discussed in this paper.
