Theoretical efficiency

In physics, the radiative efficiency limit (also known as the detailed balance limit, Shockley–Queisser limit, Shockley Queisser Efficiency Limit or SQ Limit) is the maximum theoretical efficiency of a solar cell using a single p-n junction to collect power from the cell where the only loss mechanism is radiative recombination in the solar cell. It was first calculated by William Shockley and Hans-Joachim Q… Webbhand, efficiency is interrelated with all of the peripheral parameters that also influence hydrogen generation costs, such as operating mode (operating hours) service life and …
