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...

Chlorophyll source of electrons will be excited when exposed light, resulting an electric current ...

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 an expedition for green-energy generation and to lower the cost per watt of solar energy, environmentally friendly biotic colorants were separated from Tectona grandis seeds. The prime colorant in extract is pelargonidin which sensitizes titanium dioxide (TiO2)-based photo anodes. pelargonidin-sensitized TiO2 nanomaterials endured structural, photosensitive, spectral current-voltage interpre...

<span lang="EN-US">Natural dye-sensitized solar cells (DSSC) have gained so much attention in recent years due to its low-cost fabrication process, ease of fabrication, and environmentally friendly. In order improve the DSSC performance, absorbance spectral dyes must reach maximum visible spectrum values. The combination two with different spectra can be utilized expand spectral. Here, we...

A mesoscopic nitrogen-doped TiO2 sphere has been developed for a quasi-solid-state dye-sensitized solar cell [DSSC]. Compared with the undoped TiO2 sphere, the quasi-solid-state DSSC based on the nitrogen-doped TiO2 sphere shows more excellent photovoltaic performance. The photoelectrochemistry of electrodes based on nitrogen-doped and undoped TiO2 spheres was characterized with Mott-Schottky a...

Abstract Dye-Sensitized Solar Cells (DSSC), a 3rd generation solar cell has gained huge attention in the field of photovoltaics as substitute for silicon cell. The performance DSSC mainly depends on all important components such transparent conductive oxide substrate, cathode, photo-anode, dye, and electrolyte. Additionally, sensitizing dyes also perform vital role absorption light conversion e...

Sensitizers are responsible for the light harvesting and the charge injection in dye-sensitized solar cells (DSSCs). A fast dye-regeneration process is necessary to obtain highly efficient DSSC devices.
