Abstract

We investigated the effects of cetyltrimethylammonium bromide (CTAB) in organic-quantum dot hybrid solar cell. Hybrid active layer was composed of poly (3-hexylthiophene) (P3HT) and PbS colloidal quantum dot (CQD). By employing hybrid active layer, which absorbed the light in wide range, expected power conversion efficiency of hybrid solar cell will be increased. However, PbS CQD has relatively low performance compared with P3HT. We used CTAB as inorganic ligand of PbS CQD surface. As a result, we observed short circuit current density of hybrid solar cell and open circuit voltage were increased.
