Sentence examples for been found that PbSe from inspiring English sources

However, it has been found that PbSe QDs are not stable [6, 7].

It has been found that PbSe formation is possible at potentials more positive than the Nernst potential EPb2+/Pb0.

It has been found that [100] oriented growth of PbSe crystallites takes place in some regions of Pb II) and Cd II) concentration.

He's found that".

Because the PbSe films were found to be considerably more conductive than the CdSe films, we suggest that the PbSe layer is effectively behaving like a low conductivity electrical contact; therefore, this solar cell architecture does not follow typical type-II heterojunction donor/acceptor models used to describe organic polymer solar cells.

We report on solar cells consisting of a sintered active bilayer of CdSe and PbSe nanoparticles in the structure ITO/CdSe/interlayer/PbSe/Al, where an interlayer of LiF or Al2O3 was found necessary to prevent low shunt resistance from suppressing the photovoltaic behavior.

It is expected that PbSe QDs active layer provides wider interface and surface areas for efficient exciton dissociation and charge transport, as well as more photon capture and exciton generation by absorption in near infrared spectrum region.

Cánovas et al. studied the electron transfer processes from PbSe quantum dots to SnO2 and found that the injection time of the photoexcited electron was vitally affected by the QD size [13].

In conclusion, we observed a tail of defect states extending into the bandgap of zinc oxide, characteristic of polycrystalline films, and found that these states reduce the energy of electrons collected from the ZnO PbSe CQDSCs and hence the achievable VOC.

It has been known that unpassivated PbSe QDs surface is a Pb atom-rich shell [6, 7].

A measurable photocurrent was still obtained when the Zn1 xMgxO conduction band was above that of the PbSe QDs (when x > 0), indicating that a tail of conduction band states in the Zn1 xMgxO was actively accepting electrons from the PbSe quantum dots and transporting electrons to the electrode.
