Sensitized solar cells with colloidal PbS-CdS core-shell quantum dots.
We report on the fabrication of PbS-CdS (core-shell) quantum dot (QD)-sensitized solar cells by direct adsorption of core-shell QDs on mesoporous TiO2 followed by 3-mercaptopropionic acid ligand exchange. PbS-CdS QD-sensitized solar cells show 4 times higher efficiency with respect to solar cells sensitized with PbS QDs. The significantly enhanced mean electron lifetime and electron diffusion l...
متن کاملحساس سازی همزمان سلول‌های خورشیدی نقاط کوانتومی متشکل ازفوتوآند نانوبلوری TiO2 با نانوذرات CdS و PbS و بررسی تأثیر نقاط کوانتومی PbS بر عملکرد سلول خورشیدی
In this research, CdS and PbS quantum dots were applied as the light sensitizers in TiO2 based nanostructured solar cells. The PbS quantum dots could absorb a wide range of the sunlight spectrum on earth due to their low bandgap energy. As a result, the cell sensitization is more effective by application of both CdS and PbS quantum dots sensitizers. The TiO2 nanocrystals were synthesized throug...
متن کاملEffect of PbS Film Thickness on the Performance of Colloidal Quantum Dot Solar Cells
Colloidal quantum dots offer broad tuning of semiconductor band structure via the quantum size effect. In this paper, we present a detailed investigation on the influence of the thickness of colloidal lead sulfide (PbS) nanocrystals (active layer) to the photovoltaic performance of colloidal quantum dot solar cells. The PbS nanocrystals (QDs) were synthesized in a non-coordinating solvent, 1-oc...
متن کاملBiomineralization of PbS and PbS–CdS core–shell nanocrystals and their application in quantum dot sensitized solar cells†
Biomineralization utilizes biological systems to synthesize functional inorganic materials for application in diverse fields. In the current work, we enable biomineralization of quantum confined PbS and PbS–CdS core–shell nanocrystals and demonstrate their application in quantum dot sensitized solar cells (QDSSCs). An engineered strain of Stenotrophomonas maltophilia is utilized to generate a c...
متن کاملControlling photoinduced electron transfer from PbS@CdS core@shell quantum dots to metal oxide nanostructured thin films.
N-type metal oxide solar cells sensitized by infrared absorbing PbS quantum dots (QDs) represent a promising alternative to traditional photovoltaic devices. However, colloidal PbS QDs capped with pure organic ligand shells suffer from surface oxidation that affects the long term stability of the cells. Application of a passivating CdS shell guarantees the increased long term stability of PbS Q...
