dc.description.abstract | thereby achieving the maximum PCE of 13.8 % in hybrid solar cells. Moreover, we developed the CQD-based avalanche photodiode with 80 of multiplication gain and 1 Χ 1014 jones by implementing the CQD/organic ligand interfaces. | - |
dc.description.abstract | however, the hybrid devices has poor performances due to inefficient charge extraction at heterointerfaces. In this dissertation, we systematically investigate the carrier dynamics at organic-inorganic heterointerfaces, and enhance the photovoltaic performances by inducing the efficient charge extraction in hybrid devices. First, we improved the charge extraction properties by introducing the small molecule bridge and interfacial layer | - |
dc.description.abstract | Colloidal quantum dot (CQD) is an excellent candidate for emerging semiconducting material because it allows to tune the electrical and chemical properties by changing the size of them. Moreover, the hybrid structure combining the CQD with organic molecules, which have the high flexibility, creates the synergistic effects by achieving both advantages | - |
