We report CVD-grown p-doped three-dimensional graphene nano-networks (3D-GNs) that provide superior performance to Pt as a counter electrode material in dye sensitized solar cells (DSSCs). The 3D-GN based DSSC exhibits a maximum photoconversion efficiency of 8.46%, which is 6.01% greater than that exhibited by Pt based DSSCs.

Dye-sensitized solar cells (DSSC) are known as 3rd generation cells. One of the most important parameters affecting performance DSSCs is thin film thickness that forms photoanode layer. In this study, we examined how 38, 60 and 76 µm thick TiO2 films change dye-sensitized cell performance. The highest efficiency (4.73%) was seen in with 38 thickness. addition, mineralogical morphological analys...

Dye-Sensitized Solar Cell (DSSC) is a solar cell that uses dyes to convert sunlight into electricity, which has wide absorption spectrum, inexpensive and environmentally friendly. Visible light sensitive are used in types generate electricity. Natural commonly DSSC chlorophyll derived from plants. Chlorophyll source of electrons will be excited when exposed light, resulting an electric current ...

In this paper, the comparative studies of dye sensitized solar cells (DSSC) manufactured with different cathode materials have been investigated. It has been observed that different cathode materials have different bandgap energies and it directly affect the efficiency of DSSC. The tested materials for counter electrode are carbon black and graphite. Although both of these materials are carbon ...

In the photoelectrode, the important factor to achieve high efficiency of DSSC is weak acid treatment rather than specific regime of heat treatment. Acid treated paste of titanium oxide nano particles enhanced a factor of three higher of the energy conversion efficiency(none (η=2.0%), H2SO4(η=1.7%), HCl(η=2.8%), CH3COOH(η=6.2%) in dye-sensitized solar cells (DSSCs). The effects of the different...

Current work employs dye extracted from leaves of Costus woodsonii as a new sensitizer for dye-sensitized solar cells (DSSCs). The leave was in three different solvents namely ethanol, methanol, and acetone. Extraction carried out by the freezing method. DSSCs with configuration TiO2/dye/electrolyte/Pt were assembled. dyes DSSC methanol extract has an efficiency 0.23 % short-circuit current den...

In this study, aligned zinc oxide (ZnO) nanorods (NRs) with various lengths (1.5-5 µm) were deposited on ZnO:Al (AZO)-coated glass substrates by using a solution phase deposition method; these NRs were prepared for application as working electrodes to increase the photovoltaic conversion efficiency of solar cells. The results were observed in detail by using X-ray diffraction, field-emission sc...

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...
