What is the maximum efficiency of a solar cell?
If we bear in mind that in a real situation the solar cell does not operate always in maximum concentration and the solid angle under which the cell sees the sun is in fact only a minute fraction of a hemisphere, the maximum efficiency is not larger than 12.79%, which is actually lower than most recently fabricated solar cells.

What is the maximum efficiency of solar energy conversion?
This efficiency is maximum (η c = 1) if the converter temperature is 0 K and the solar energy is totally converted into electrical work, while η c = 0 if the converter temperature is identical to that of the sun T s the system is in thermal equilibrium so there is no energy exchange.
How is solar cell efficiency measured?
In addition to reflecting the performance of the solar cell itself, the efficiency depends on the spectrum and intensity of the incident sunlight and the temperature of the solar cell. Therefore, conditions under which efficiency is measured must be carefully controlled in order to compare the performance of one device to another.
