Which mechanism limits carrier mobility in organic molecular semiconductors under intense illumination?

💡 Explanation

Under intense illumination, organic molecular semiconductors experience polaron formation because excess charge carriers distort the lattice, creating localized states with stronger electron-phonon interactions effectively increasing the carrier's mass, which then limits mobility. Therefore polaron formation limits motility rather than gap widening, recombination or scattering which require different interaction processes.
