Abstract: The kinetic model has been developed for disserting the efficiency of solar energy conversion as a function of light intensity. A comparison of theory with experimental results shows that the model provides a satisfactory agreement. We have estimated the essential parameters of photosynthetic systems (the size of the photosynthetic antenna, the rate of electron transport, the correlation between photosynthesis and respiration) that are responsible for reaching the maximum efficiency at "one sun" and "one hundred suns" light illumination intensities. Recommendations for the improvement of photosynthetic system parameters using genetic engineering methods are also provided.
