We synthesized the Cu(II) and Zn(II) complexes of the 2,7,12,17-tetrapropionic acid of 3,8,13,18-tetramethyl-21H,23H porphyrin (coproporphyrin-I) and successfully employed them as sensitizers in dye-sensitized solar cells. Copper(II) coproporphyrin-I exhib ...

Novel donor-p-acceptor (D--A) dyes, coded as SD-1, SD-2 and SD-5, were designed and synthesized for dye-sensitized solar cells. All these dyes comprised the same donor and acceptor units while the oligo thiophene units were introduced as linkers between th ...

We present efficient perovskite solar cells using a mesoscopic TiO2/Al2O3/NiO/carbon structure as framework. The CH(3)NH(3)Pbl(3)-based device with quadruple-layer architecture achieves a power conversion efficiency of 15.03% under AM 1.5G illumination. De ...

We have tested the photovoltaic metrics of CH3NH3PbI3 perovskite solar cells over a wide temperature range from 80-360 K. Our investigation reveals that the open-circuit voltage reaches a maximum value at about 200 K close to the phase transition from tetr ...

The invention discloses a perovskite solar cell and a method of fabrication thereof. The perovskite solar cell sequentially comprises a transparent electrode, a mesoporous P-I-N framework and a counter electrode from the bottom to top; the mesoporous P-I-N ...

The production fractions of (B) over bar (0)(s) and Lambda(0)(b) hadrons, normalized to the sum of B- and (B) over bar (0) fractions, arc measured in 13 TeV pp collisions using data collected by the LHCb experiment, corresponding to an integrated luminosit ...

Decays of B-s(0) and (B) over bar (0)(s) mesons into J/psi pi(+)pi(-) final states are studied in a data sample corresponding to 1.9 fb(-1) of integrated luminosity collected with the LHCb detector in 13 TeV pp collisions. A time-dependent amplitude analys ...

Results are reported from a search for the rare decays B-s(0) -> tau(+/-)mu(+/-) 1T and B -> tau(+/-)mu(+/-), where the r lepton is reconstructed in the channel r- irrg vr. These processes are effectively forbidden in the standard model, hut they can poten ...

Dye-sensitized solar cells (DSCs) have achieved impressive conversion efficiencies for solar energy of over 11% with an electrolyte that contains triiodide/iodide as a redox couple. Although triiodide/iodide redox couples work efficiently in DSCs, they suf ...

Black phosphorus quantum dots (BPQDs) are proposed as effective seed-like sites to modulate the nucleation and growth of CsPbI2Br perovskite crystalline thin layers, allowing an enhanced crystallization and remarkable morphological improvement. We reveal t ...

A heteroleptic polypyridyl ruthenium complex, cis-Ru(4,4-bis(5-octylthieno[3,2-b]thiophen-2-yl)-2,2-bipyridine)(4,4-dicarboxyl-2,2-bipyridine)(NCS)2, with a high molar extinction coefficient of 20.5 × 103 M-1 cm-1 at 553 nm has been synthesized and demonst ...

TiO2 nanorod arrays were prepared on top of a transparent conductive glass substrate covered with a thin TiO2 compact layer. Solid-state dye-sensitized solar cells (SSDSCs) were fabricated using these structured TiO2 films sensitized with C106 dye as a pho ...

In response to the 2013 Update of the European Strategy for Particle Physics (EPPSU), the Future Circular Collider (FCC) study was launched as a world-wide international collaboration hosted by CERN. The FCC study covered an energy-frontier hadron collider ...

A ruthenium sensitizer (coded C101, NaRu (4,4'-bis(5-hexylthiophen-2-yl)-2,2'-bipyridine) (4-carboxylic acid-4'-caboxylate-2,2'-bipyridine) (NCS)(2)) containing a hexylthiophene-conjugated bipyridyl group as an ancillary ligand is presented for use in soli ...

In pursuit of efficient quantum dot (OD)-sensitized solar cells based on mesoporous TiO2 photoanodes, a new procedure for preparing selenide (Se2-) was developed and used for depositing CdSe QDs in situ over TiO2 mesopores by the successive ionic layer ads ...

We report an efficient nonplatinized flexible counter electrode for dye-sensitized solar cells. In combination with a solvent-free ionic Liquid electrolyte, we have demonstrated a similar to 6.5% cell with an amphiphilic ruthenium polypyridyl photosensitiz ...

Redox electrolytes have proven to be extremely important in determining the performance of dye-sensitized solar cells (DSCs). The design and understanding of the redox couple, especially iodide free systems, has become a recent focus of DSC electrolyte res ...
