Abstract In this research, treated metakaolinite (TMK) was introduced into the TiO 2 photoelectrode to fabricated dye-sensitized solar cells (DSSCs). The photovoltaic have four main natural components, i.e., a photosensitizer (carotenoid bixin), (TiO /kaolinite), electrolyte (glycerine carbonate derivative), and counter-electrode (carbon). Their stability, reusability, equivalent circuit were s...

The most efficient dye-sensitized solar cells (DSSCs) have had essentially the same configuration (nanoparticle TiO2 sensitized with [Ru(4,4 -dicarboxy-2,2-bipyridine)2(NCS)2] in contact with I3 /I ) for the last 17 years. In this article we outline the strategies for improving each of the three major photo-relevant components of a DSSC, review literature reports consistent with these strategie...

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 ...

Octahedral and cubic NiS2 nanocrystals enclosed by {111} and {100} planes were separately used as counter electrodes (CEs) incorporated into Pt-free dye-sensitized solar cells (DSSCs). The DSSC assembled by NiS2 octahedrons exhibited a conversion efficiency of 5.98%, better than that by NiS2 cubes (5.43%). DFT calculations indicate that the better catalytic effect could be ascribed to higher su...

A series of alkyl-group-wrapped and halogen atom functionalized unsymmetrical squaraine dyes ( ISQ ) were designed synthesized. maximum DSSC device efficiency 7.80% was achieved for iodine funtionalized ISQ-I dye in Z-150 with CDCA.

The counter electrode (CE) containing catalyst layer and transparent conducting oxide (TCO) is by far the most expensive components in Dye sensitized solar cells (DSSC) due to use of rare earth element such as Pt. potential replacement both TCO Pt-based would essentially pave way mass commercialization technology DSSC. In this investigation, an attempt has been made replace Pt with a single del...

Nanomaterials play important role in performance of dye-sensitized solar cells. In this paper, highly phase pure anatase TiO2 microspheres were synthesized using a low-cost hydrothermal route. Initially, X-ray diffraction studies and Raman spectroscopic analysis carried out, the formation tetragonal structure with was confirmed. The UV–Vis DRS showed excellent reflectance optical band-gap energ...

A dye-sensitized solar cell (DSSC) device using Mg-doped Zn thin films as photoanode and fruit extract of rose myrtle (Rhodomyrtus tomentosa) the natural dye was investigated. The effect annealing temperature (400-550°C) on systematically studied an X-ray diffractometer (XRD), UV-Visible Near Infrared (UV-Vis NIR) Spectrophotometer, scanning electron microscopy (SEM), energy dispersive spectros...

This work enlightened the synthesis of graphenated-carbon nanotubes sheet (g-CNT) using floating-catalyst chemical vapor deposition method (FCCVD) for dye-sensitized solar cell (DSSC) application. The carbon injection flow rate in experiment was varied to 6, 8, and 10 ml/h. morphological findings revealed that g-CNT formed a highly conductive network. Excellent conductivity obtained sample g-CN...
