In the recent years, the heterojunction solar cells based on quantum dots (QDs) have attracted attention due to strong light absorbing characteristics and the size effect on the bandgap tuning. This paper reports on the kinetics of interfacial charge separ ...

The optoelectronic properties of transparent nanocrystalline TiO2 films were modified by the incorporation of a low level of Ga3+ or Y3+ cations. After optimizing their relative concentration level, we were able to increase in a noticeable manner the power ...

We prepared a quasi-solid electrolyte for dye-sensitized solar cells (DSSCs) that consist of ionic liquid and modified silica particles. Commercial bare silica F5 particles and modified silica F5 by NH2 and NH3+ groups were prepared, and fully characterize ...

The power conversion efficiency of a dye-sensitized solar cell with tailored squaraine dye enhanced by 47%, due to Forster resonance energy transfer from CdSe quantum dots to the squaraine dye. The incident photons to collection efficiency of electrons ind ...

Zinc oxide-titanium dioxide core-shell nanowire dye-sensitised solar cells have been synthesised, making use of a recently developed organic dye and iodide-based electrolyte. We have been able to demonstrate a cell efficiency of 2.53% under AM1.5 for our s ...

Quasi type-II PbSe/PbS quantum dots (QDs) are employed in a solid state high efficiency QD/TiO2 heterojunction solar cell. The QDs are deposited using layer-by-layer deposition on a half-micrometer-thick anatase TiO2 nanosheet film with (001) exposed facet ...

We report for the first time on co-sensitization between CH3NH3PbI3 perovskite and PbS quantum dots (QDs) in a heterojunction solar cell to obtain a panchromatic response from the visible to near IR regions. Following the deposition of the sensitizers on a ...

The present invention provides a solid state heterojunction solar cell comprising a transparent conducting support layer (2,3), on which a nanostructured, surface-increasing scaffold structure is provided, wherein an organic-inorganic perovskite layer (4) ...

Solid state PbS quantum dots (QDs)/TiO2 heterojunction solar cells were produced by depositing PbS QDs on a 500 nm thick mesoscopic TiO2 films using layer-by-layer deposition. Importantly, the PbS QDs act here as photosensitizers and at the same time as ho ...

A novel bifunctional linker molecule, bis(4-mercaptophenyl)phosphinic acid, is designed to be used in a QDs solar cells. The linker anchors to TiO2 mesoporous film through the phosphinic acid functional group and to the PbS QDs through the two thiol groups ...

A method has been developed to synthesise zinc oxide nanowire arrays that demonstrate superior device performance compared to conventional ZnO nanowires within dye sensitised solar cells (DSSCs). This simple yet effective methodology has produced nanowires ...

The first solution-processed depleted bulk heterojunction colloidal quantum dot solar cells are presented. The architecture allows high absorption with full depletion, thereby breaking the photon absorption/carrier extraction compromise inherent in planar ...
