  • Closer Look at the Capacity of SLA Batteries and Solar Energy Systems

    Sealed lead acid (SLA) batteries have a reputation for being durable when used to support portable electronic devices. They require minimal maintenance and offer leak-proof capabilities. But when used with solar energy systems, the units present issues that can hinder the potential and performance of the machines. For example, general purpose SLA batteries should not be deep cycled, as ...

  • Gold nanoparticles functionalised with Ru–dicarboxybipyridine–trimercaptotriazine: SERS effect and application in plasmonic dye solar cells

    A dicarboxybipyridine–trimercaptotriazine ruthenium complex, primarily designed for dye–sensitised solar cells (DSSC), has been successfully employed in the generation of electrostatically stabilised gold colloids, because of its high negative charge and capability of binding to gold nanoparticles via the sulphur groups. Strong SERS enhancements have been obtained for the isolated gold ...

  • Photodetectors and solar cells with Ge/Si quantum dots parameters dependence on growth conditions

    In this paper recommendations for growth conditions necessary for achieving maximum detectivity of infrared photodetectors with quantum dots and efficiency of quantum dot solar cells are given. It is also shown that for improvement of photodetectors characteristics quantum dots should be grown at rather high temperatures, and, on the contrary, at relatively low temperatures for maximisation of ...

  • Review of titanium dioxide nanoparticle phototoxicity: Developing a phototoxicity ratio to correct the endpoint values of toxicity tests

    Titanium dioxide nanoparticles are photoactive and under natural sunlight, produces reactive oxygen species. Reactive oxygen species can be detrimental to many organisms, causing oxidative damage, cell injury, and death. Most studies investigating TiO2 nanoparticle toxicity did not consider photoactivation and performed tests either in dark conditions or under artificial lighting that did not ...

  • Emissions through solar PV systems – a review

    Photovoltaic (PV) system has been quoted for wide range of green house gas (GHG) emissions through life cycle assessment (LCA) studies. There are a variety of solar cell materials available, which vary in conversion efficiency and emission of CO 2 . This paper is based on the LCA analysis of PV system which starts from the production of these solar cells and goes through the stages known as ...

  • Effect of Au nanoparticles added in nanocrystalline TiO
    film on the photoelectrode of dye–sensitised solar cells

    In this study, we used a citrate reduction method and electrophoretic deposition (EPD) to prepare hybrid nanocrystalline TiO2/Au films and applied it to the photoelectrode of dye–sensitised solar cell. The films and solar cells were investigated by field emission scanning electron microscopy (FE–SEM), energy dispersive X–ray analysis (EDX), X–ray diffraction (XRD), I–V ...

  • In situ indium–induced crystallisation of low temperature nano–poly silicon (LTNPS) thin film on ITO glass substrate

    For the first time, the low temperature nano–poly silicon (LTNPS) thin films were formed on indium tin oxide (ITO) glass with a temperature of ∼200ºC using the in situ indium–induced crystallisation of the plasma enhanced CVD (PECVD) deposited a–Si. Compared with the conventional method for transfer of the PECVD formed amorphous structure to the nano–poly one, the technology features a low ...

  • The effect of ethyl cellulose on TiO
    pastes for DSSCs application

    Ethyl cellulose (EC)–based TiO2 pastes were prepared in order to fabricate flat and crack–free TiO2 films employing screen–printing technique. Pure anatase TiO2 was synthesised via hydrothermal process using titanium (IV) n–butoxide as Ti–precursor and peptised by acetic acid. The as–prepared ...

  • Near Term Lower Cost Solar Electric Power for US Commercial Customers

    Market Opportunities The first market for PV electric power panels was for space satellites. While the single crystal cells used in these panels made these panels very expensive, this was unimportant for that market. That market emphasized reliability, not cost. As these panels came down to earth for off-grid remote applications, again the emphasis was on reliability and low maintenance, not ...

  • TPV History from 1990 to Present & Future Trends

    Abstract. Herein, the history of TPV at JX Crystals over the last 15 years is described. Our focus has been on commercial application for TPV components and systems. JX Crystals began as a spin off company when the inventors of the GaSb cell left Boeing with a license to make that cell at JX Crystals. We recosnized that III-V IR sensitive cells such as the GaSb cell were enabling for TPV systems. ...

  • Highly crystalline hydrothermal ZnO nanowires as photoanodes in DSCs

    Vertically aligned ZnO nanowires (NWs) were prepared inside an autoclave by a hydrothermal procedure at temperatures above 100°C (HP). The effects of synthesis temperature and time on the morphology of ZnO NWs were carefully studied. The performance of HP ZnO NWs was compared with that of ZnO NWs grown by a conventional ambient pressure hydrothermal method at temperatures below 100°C (LP) ...
