Toward the extension of the light-harvesting region of sensitizers in dye-sensitized solar cells (DSSCs), two ethynyl-linked porphyrin trimers were synthesized and investigated. The zinc–freebase–zinc trimer (Zn–FbA–Zn) showed an absorption maximum at a longer wavelength than the all-zinc trimer (Zn–ZnA–Zn), although the energy level of Zn–FbA–Zn was lower than that of Zn–ZnA–Zn. The DSSCs usin...

This study investigates the extent to which the TiO2/graphene/TiO2 sandwich structure improves the performance of dye-sensitized solar cells (DSSCs) over that of DSSCs with the traditional structure. Studies have demonstrated that the TiO2/graphene/TiO2 sandwich structure effectively enhances the open circuit voltage (V oc), short-circuit current density (J sc), and photoelectrical conversion e...

Dye sensitized solar cell (DSSC) being one of the main focus in area of photovoltaic after silicon solar cell, modeling and estimating their parameters becomes important for their analysis and enhancement in their performance. We have proposed an analytical approach having no approximation for extracting various parameters of DSSC using a well known Lambert W-function technique. The model used ...

in the current study, pure tio2 and cr-doped tio2 (cr@tio2) nanoparticles were synthesized via sol-gel method and the resulting materials were applied to prepare the porous tio2 electrodes for dye-sensitized solar cells (dsscs). it is hypothesized that the advantages of the doping of the metal ions into tio2 lattice are the temporary rapping of the photogenerated electron-hole (charge carriers)...

The dye-sensitized solar cell (DSSC) has been on the market as a permanent power source for indoor IoT edge devices. In recent years, illumination technology experiencing drastic transition from incandescent and fluorescent lamps toward solid-state lighting devices with light-emitting diodes (LEDs). addition to high efficiency, virtue of LEDs is their prompt response, which enables precise chan...

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...

DSSC (dye-sensitized solar cell) is a third-generation photovoltaic technology that can convert energy into electric current using photoelectrochemical mechanism. Photoelectrode one of the significant elements in DSSC, where photoexcited electrons are generated, and serves as an electron transport medium. Anatase titanium dioxide (TiO2) often used photoelectrode material because its excellent p...

Abstract In this work new naphthalenediimides (NDIs) were synthesized and used as dyes in DSSC. The efficiency ( η ) of the DSSC is influenced by NDIs electronic structural characteristics. It was found a better cell performance with which have broader absorption band shifted to red color, high ƹ values, more adsorption anode surface. gaps determinate UV–vis cyclic voltammetry. LUMO orbitals mo...

Abstract Photoanode of dye-sensitized solar cell (DSSC) is an inorganic semiconductor layer with a nanoporous structure that has function as charge carrier transport and dye storage. Oxide material such titanium dioxide (TiO 2 ) widely used photoanode because its wide band gap (3.2 eV) high active surface area (80 m /g), but TiO low electron diffusion recombination (electron-hole pair pairing)....
