Fire-tower is effectively applied in forest fire prevention and commanding system, especially in fire monitor and position. After explaining the significance of scientific planning of fire-tower, this paper analyzes GIS`s functions in building forest fire prevention system. This paper uses case study method, which designs a model, fire tower planning and analysis, based on MapGIS platform. Afte...

Flexible Dye-sensitized solar cells were assembled using flexible transparent electrodes as substrates, nanocrystalline TiO2, an electrolyte based on I3/I, dye molecules and a counter electrode. In this study has been employed natural pomegranate juice for sensitization of nanocrystalline TiO2 and gold layer as counter electrode was prepared by sputtering method on conducting substrates polymer...

Dye sensitised solar cells (DSSCs) use a mesoporous TiO(2) scaffold, typically assisted by an adsorbed dye, as the main active element, responsible for the photon absorption, exciton generation and charge separation functionality. The sintering process employed in the TiO(2) active layer fabrication plays a crucial role in the formation of the nanoparticle scaffold and hence the performance of ...

In this paper, extract of papaya leaves are used as a natural dye and combined by variations of solvent concentration applied on DSSC (Dye-Sensitized Solar Cell). Indonesian geographic located on the equator line occasions the magnitude of the potential to develop organic solar cells made from extracts of chlorophyll as a substitute for inorganic materials or synthetic dye on DSSC material. Dye...

Here we report the fabrication of highly transparent graphene oxide (GO) reinforced TiO2 nanocomposite thin film and demonstrate that it enhances power conversion efficiency dye-sensitized solar cells (DSSC) when used as photoanode. TiO2-GO films with varying GO concentrations are deposited on top fluorine doped tin (FTO) coated glass substrate by easy, cost-effective sol-gel spin coating techn...

The development of transparent solar cells extends the applications photovoltaics by offering opportunity to substitute gigantic surface coverage windows panels produce electricity. Herein, we report a new family NIR-sensitizers based on pyrrolopyrrole cyanine dyes, particularly efficient for fully and colorless dye-sensitized since record efficiency 2.5 % was achieved with an average visible t...

Our world is facing an environmental crisis that driving scientists to research green and smart solutions in terms of the use renewable energy sources low polluting technologies. In this framework, photovoltaic (PV) technology one most worthy interest. Dye-sensitized solar cells (DSSCs) are innovative PV devices known for their encouraging features cost easy fabrication, good response diffuse l...

Transparent nickel doped cobalt sulfide was fabricated on a SnO2:F electrode and tested as an efficient electrocatalyst and as an alternative to the expensive platinum counter electrode. In order to investigate how this electrode could affect the electrical characteristics of a dye-sensitized solar cell, we manufactured cells with the same TiO2 photoanode sensitized with dye (N719) and employin...
