The photochemical quantum efficiency (quantum yield) is nearly 100%, the energy conversion efficiency is only 27%, and the overall efficiency of conversion of solar

energy is only a few percent the solar energy storage efficiency is a measure of how much of the energy in the entire solar spectrum is converted to usable form, if it

can be measure in terms of C3 and C4 plant?
