A PV will reach the SQ limit if it's material properties match the assumptions made to derive to derive this limit. Following we can 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 Recombination  is direct (band-to-band) (band to band) and no  radiative recombination (satisfying the principle of detailed balance) is present.  * There are otherwise no limitations on the transport of charge (infinite mobility, perfectly reflecting contacts)
