Which mechanism limits maximum energy absorption in dye-sensitized solar cell when exposed to high insolation?

💡 Explanation

When exposed to high insolation, electron-hole pairs are generated rapidly but before charges can be extracted completely, Shockley-Read-Hall recombination through defects at the interface rapidly steals carriers from the external circuit limiting performance. Therefore recombination at defects limits power, rather than saturation, depletion, or delamination requiring different factors.
