Improved carrier transport in Mn:ZnSe quantum dots sensitized La-doped nano-TiO_2 thin film

Mn:ZnSe/ZnS/L-Cys core-shell quantum dots (QDs) sensitized La-doped nano-TiO_2 thin film (QDSTF) was prepared.X-ray photoelectron spectroscopy (XPS), nanosecond transient photovoltaic (TPV), and steady state surface photovoltaic(SPV) technologies were used for probing the photoelectron behaviors in the Mn-doped QDSTF. The results revealed that the Mn-doped QDSTF had a p-type TPV characteristic. The bottom of the cond...  (本文共9页) 阅读全文>>

Enhanced transient photovoltaic characteristics of core–shell ZnSe/ZnS/L-Cys quantum-dot-sensitized TiO_2 thin-film

Photoanodic properties greatly determine the overall performance of quantum-dot-sensitized solar cells(QDSCs). In the present report, the microdynamic behaviors of carriers in the nanocomposite thin-film, a Zn Se QD-sensitized mesoporous La-doped nano-TiO_2 thin-film, as a potential candidate for photoanode, are probed via nanosecond transient photovoltaic(TPV) spectroscopy. The results confirm that the L-Cys ligand ...  (本文共9页) 阅读全文>>

Effects of anchoring groups on perylenemonoimide-based sensitizers for p-type dye-sensitized solar cells and photoelectrochemical cells

In this work, two new dyes YK-1 and YK-2 with carboxylic acid and hydroxamic acid as anchoring groups,respectively, in combination with diphenylamine as donor and perylenemonoimide as acceptor were synthesized and applied in p-type dye-sensitized solar cells(p-DSCs) and dye-sensitized photoelectrochemical cells(PEC). The results showed that the sensitizer(YK-1) based on carboxylic acid displayed a higher conversion e...  (本文共8页) 阅读全文>>
