Dye-sensitized solar cell (DSSC) has a great potential to convert light into electricity. In this article, prototype of DSSC had been successfully fabricated using ZnO:Al thin film and dye from red dragon fruit as working electrode. films were prepared by sol-gel spin coating method with variation post-heating temperatures. The XRD result confirms that all have hexagonal structure crystal sizes...

Quasi solid state dye-sensitized solar cells (DSSCs) have been fabricated with electrolytes containing I−/I3 redox couple using 80 % hydrolyzed polyvinyl alcohol (PVA) doped with potassium iodide (KI) and a mixture of potassium iodide and tetrapropyl ammonium iodide (Pr4NI) salts. The quasi solid state gel polymer electrolytes were prepared using 1:1 ethylene carbonate (EC):propylene carbonate ...

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...

A hollow TiO(2) nanoribbon network electrode for dye-sensitized solar cells (DSSC) was fabricated by a biotemplating process combining peptide self-assembly and atomic layer deposition (ALD). An aromatic peptide of diphenylalanine was assembled into a three-dimensional network consisting of highly entangled nanoribbons. A thin TiO(2) layer was deposited at the surface of the peptide template vi...

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...

Introduction Dye-sensitized solar cells (DSSCs) are widely recognized as a promising alternative and cost-effective technology for solar-toelectric energy conversion. Current silicon solar cells are limited due to their lack of flexibility, high cost of manufacturing and installation, and heavy weight. Alternatively, dye-sensitized solar cells have a very simple fabrication process, low fabrica...

In times of climate change and dwindling fossil resources, the need for sustainable renewable energy technologies gains importance, increasingly fast. However, state art are intensive in their production, like monocrystalline photovoltaic, or even consist not recyclable composite material, case wind turbine blades. Despite a lack efficiency stability, dye sensitized solar cells (DSSC) have high...

Energy consumption is increasing yearly all over the world due to increase in population and demand of energy. The largely depends on a hydroelectric energy supply, thermal electric supply which non-renewable resources. Nevertheless, resources are rapidly decreasing per year rate consumption. quest for discovery another abundant resource has attracted many scientists into development renewable ...
