Talk:photodoping

To eliminate the incorporation of counter ions, “photo-doping” and “charge-injection doping” methods have been exploited

The irradiation of a conjugated polymer (e.g. trans-polyacetylene) macromolecule with a light beam of energy greater than its band gap could promote electrons from the valence band into the conduction band

Photogenerated charge carriers may disappear once the irradiation ceases, the application of an appropriate potential during irradiation could separate electrons from holes, leading to photoconductivity
