Toplumumuzdaki enerji gereksinimleri fosil yakıtları üzerine kurulmuştur fakat bu yakıtlar hem sınırlıdır de yakıtların yanmasıyla karbondioksit konsantrasyonunun hızlı artışı küresel ısınmaya ve iklim değişikliklerine neden olmaktadır. Bu koşullar altında alternatif temiz bir kaynağı olarak fotovoltaik (PV) güneş hücrelerine ilgi artmaktadır. Son yıllarda silisyum hücreleri ince film tabanlı h...

With the aim of improving the photoconversion efficiencies of heteroleptic [Cu(Lanchor)(Lancillary)](+) dyes in n-type dye-sensitized solar cells (DSCs), the previously favoured anchor ((6,6'-dimethyl-[2,2'-bipyridine]-4,4'-diyl)bis(4,1-phenylene))bis(phosphonic acid) (1) has been replaced by analogues 2 and 3 containing 2-thienyl spacers between the 2,2'-bipyridine metal-binding domain and the...

Dye-sensitized solar cells (DSCs) remain an interesting photovoltaic concept, although recent times have seen their envisioned broad-scale applications being replaced with more niche ones. Nevertheless, as a key component of DSCs, titanium(IV) oxide (TiO2) must be produced in large volume, low cost, and highly reproducible manner. Degussa P25 remains benchmark TiO2 product, addressing the first...

A series of dye-sensitized solar cells (DSCs) was constructed with TiO2 nanoparticles and N719 dye. The standard I3(-)/I(-) redox shuttle and the Co(1,10-phenanthroline)3(3+/2+) shuttle were employed. DSCs were modified with atomic-layered-deposited (ALD) coatings of Al2O3 and/or with the surface-adsorbing additive 4-tert-butyl-pyridine. Current-voltage data were collected to ascertain the infl...

We report a quantitative comparison of the photoaction spectra, short circuit current densities, and power conversion efficiencies of dye-sensitized solar cells (DSSCs) that contain bilayers of nanocrystalline TiO2 (nc-TiO2) and titania inverse opal photonic crystals (PCs). Cells were fabricated with PC/nc-TiO2 and nc-TiO2/PC bilayer films on glass/tin oxide anode of the cell, as well as in a s...

This work focuses on the design of composite photoanodes with dual-mode luminescent function as well as the effects of luminescent phosphors on the photoelectric properties of dye-sensitized solar cells. Specifically, hexagonal phase NaYF4:Yb(3+)/Er(3+) microcrystals were prepared by a hydrothermal method and added to the TiO2 photoanodes of dye-sensitized solar cells. The results indicated tha...

Materials preparation. Synthesis of nitrogen-doped carbon nanotubes with confinement of Co or Ni nanoparticles was carried out according to previous reported. [1] In brief, dicyandiamide (12 mmol) was mixed with cobalt(II) chloride hexahydrate (CoCl 2 ·6H 2 O, 0.84 mmol). After grinding for 15 min, the homogeneous mixture was placed on an alumina boat and heated at 500 °C in a tube furnace for ...

Platinum nanocubes (PtNCs) were deposited onto a fluorine-doped tin oxide glass by electrochemical deposition (ECD) method and utilized as a counter electrode (CE) for dye-sensitized solar cells (DSSCs). In this study, we controlled the growth of the crystalline plane to synthesize the single-crystal PtNCs at room temperature. The morphologies and crystalline nanostructure of the ECD PtNCs were...
