Transparent and colorless solar cells are attractive new photovoltaic devices as they could bring opportunities to harness sunlight energy particularly for their integration in windows. In this work, a zinc phthalocyanine was synthesized investigated sensitizer dye-sensitized cell (DSSC) purpose. The features benzoic acid anchoring group six thio(4-tertbutylphenyl) substituents α position of th...

Four key parameters namely light trapping, density of light harvesting centre, photoinduced electron injection and electron transport without self-recombination are universally important across all kinds of solar cells. In the present study, we have considered the parameters in the context of a model Dye Sensitized Solar Cell (DSSC). Our experimental studies reveal that carbonate doping of TiO2...

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...

Almost all types of solar cells suffer from a decreased power output when the incident light is tilted away from normal since the incident intensity generally follows a cosine law of the incident angle. Making use of the blue shift nature of the Bragg position of a TiO2 nanotube photonic crystal (NT PC) under oblique incidence, we demonstrate experimentally that the use of the NT PC can partial...

We have designed and synthesized a new thiocyanate-free sensitizer coded as SPS-01 and used it as the sensitizer in a TiO(2) based nanocrystalline dye-sensitized solar cell (DSSC). SPS-01 exhibits strong visible absorption properties with maximum peak around at 532 nm. The overall power conversion efficiency (PCE) of a DSSC sensitized with SPS-01 (7.96%) is higher than that of N719 (7.30%) unde...

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...

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 ...

Increasing demands for wearable energy sources and highly flexible, lightweight photovoltaic devices have stimulated the development of textile-structured solar cells. However, the former approach of wire-type solar cell fabrication, followed by weaving of these devices, has had limited success, due to device failure caused by high friction forces and tension forces during the weaving process. ...
