In September 2015, the ONU approved Global Agenda for Sustainable Development, by which all countries of world are mobilized to adopt a set goals be achieved 2030. Within these goals, aim having responsible production and consumption, as well taking climate action, made is necessary design new eco-friendly materials. Another important UN goal possibility in access affordable energy. The most pr...

A dye-sensitized solar cell (DSSC) fabricated by using a novel silyl-anchor coumarin dye with alkyl-chain substitutes, a Br3-/Br- redox electrolyte solution containing water, and a Mg2+-doped anatase-TiO2 electrode with twofold surface modification by MgO and Al2O3 exhibited an open-circuit photovoltage over 1.4 V, demonstrating the possibility of DSSCs as practical photovoltaic devices.

Two organic compounds (SC-23=(E)-2-Cyano-3-(2,3-dimethoxyphenyl) acrylic acid and SC-25=(E)-2-Cyano-3-(2,5-dimethoxyphenyl) acrylic acid) involving methoxy groups as the electron donor and cyanoacrylic acid group as the electron acceptor have been investigated for dye sensitized solar cells. They shows a short-circuit current density (Jsc) of 2.08 and 1.81 mA cm-2, an open circuit voltage (Voc)...

Four natural dyes were extracted from different fruits used in the Dye-sensitized solar cell (DSSC). It includes ber, blackberry, black grapes, and blueberry by individual dye or combined with other dyes. The solution's absorption spectra extended to whole visible region 200–750 nm. FTIR spectroscopy was employed identify possible functional group vibrations responsible for dyes' chemical activ...

Dye-sensitized solar cells (DSSCs) are considered a promising future source of low-cost solar power. At present, however, the most efficient DSSC designs utilize iodide-based electrolytes, which are highly corrosive and absorb strongly in some regions of the visible spectrum. We have been able to generate significant efficiency increases in DSSCs employing a novel sulfide/thiolate redox couple ...

In this work, a new family of triphenylamine-based dyes equipped with ferrocene (Fc)-containing donors have been synthesized, characterized, and studied within dye-sensitized solar cells (DSSC). With the objective designing redox-robust iron-containing dye that effectively sensitizes titania, five structurally related containing were prepared. The physicochemical properties all dyestuffs using ...

in this investigation, ag@tio2 nanocomposite was prepared by deposition of silver nanoclusters onto commercial tio2 nanoparticles (known as p25 tio2) via photodeposition technique as clean and simple photochemical route. the synthesized ag@tio2 nanocomposite was utilized in the fabrication of dye-sensitized solar cell (dssc) chiefly because, compared to pure tio2, the electron affinity of ag@ti...

Indacenodithiophene-core-based D–π–A-type organic sensitizers with two different donor antennas (triphenylamine and phenothiazine) were designed synthesized for use as light-harvesting materials in dye-sensitized solar cell (DSSC) applications.

Abstract Photoanode is an essential part in dye sensitized solar cells (DSSC). Semiconductor materials, such as TiO 2 , ZnO, and SnO are commonly used photoanode material. In this study, DSSC was fabricated using obtained from Bangka ilmenite concentrate by caustic fusion method followed water leaching, acid sol-gel reactions. The synthesized powder has anatase phase with a crystal size of 9.55...
