i.e. assumption made by Shockley to get to the SQ limit  A PV will reach the SQ limit if it matches it's material properties match  the assumption assumptions  made to derive to derive  this limit. Table () summarizes th difference between ideal and real materials, which helps guide which components Following we  can be improved to improve efficiency. compare these assumptions with real material conditions:  * All incident light is absorbed below the band gap of the material, and each absorbed photon generates an electron-hole pair  * The only source of recombination is direct (band-to-band) radiative recombination (satisfying the principle of detailed balance)
