  • 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 ...

    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 ...

  • Sunscreen’s Dark Side

    In 2013, more than 200 million tourists sunbathed on Mediterranean beaches. You can bet that most of them applied sunscreen. That sunscreen may be valuable for preventing skin cancer for humans, but it can also wreak havoc on marine ecosystems. A new study published in Environmental ...

  • 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) ...

  • Comparative study of TiO 2 films prepared by EPD and sol-gel techniques and their use in DSSCs

    In this work, we give a comparative study of titanium dioxide (TiO 2 ) films fabricated using the electro-phoretic deposition technique (EPD) and the sol-gel one. The TiO 2 films were elaborated on commercial ITO layers and were used as photo electrodes in dye sensitised solar cells (DSSCs). To fabricate these cells, we used N 3 as the sensitising dye, the electrolyte is a ...

  • Highly-Standardize Batteries for Express Convenience

    Batteries of any kind matters to the preservation of renewable energies. Hence, we are referring to the ways of preservation of renewable energies here, including solar and wind energy. In fact, the availability of solar and wind energy is passively argued in several times because solar energy is precisely presence in ...

  • Performances of natural dye–sensitised solar cells - a brief review

    Dye–sensitised solar cells (DSCs), also called as photoelectrochemical cells, have the potential of commercial viability and are the most promising photovoltaic devices among the new generation of renewable energy systems. The dye used is responsible for the light harvesting efficiency and electron injection efficiency of the DSC. Vast amount of work has been done on the performance of DSCs with ...

  • Solar powered solid oxide fuel cell with thermoelectric generator

    Durable, location independent, environmental–friendly sources of energy which allow for modular, few moving parts, low operating noise, high electricity generation efficiency and compact technology are highly desirable. Solid oxide fuel cells (SOFCs) are promising for such energy system development, since they are energy efficient and, if pure hydrogen is used, have virtually no emissions of ...

  • Where Are We Now? A Brief Overview of the Current Solar Industry

    Although there have been reports of a decline in renewable energy investment over the past few years, the outlook for the current solar industry has been improving. In 2012, a total of 31 gigawatts of solar capacity was installed, while 39 gigawatts of capacity was installed in 2013 even though overall investment in solar energies fell by 23 percent between the two years. According to the ...

  • Development of a low cost roll–to–roll nanoimprint lithography system for patterning 8–inch wide flexible substrates

    Recent developments in flexible electronics, solar cells, displays, bio–chips and wearable technology have featured various micro/nanostructures in system designs. However, fabricating these micro/nanostructures on flexible substrates using existing technology such as photolithography, electron beam lithography (EBL) and other lithography techniques are troublesome, time consuming and costly. An ...

  • Car Makers Show off New Developments in Storing Solar Energy

    On cloudy days and once the sundown is down, either a homeowner with solar panels to harness power is conserving their usage of electricity or they are back online with their utility providers.  Carmakers claim to have an answer to this dilemma of storing solar energy in batteries for later use. Experimental Technologies in Homes A ...

  • CPV solar power system

    There are relatively few CPV applications still pursuing Si cells. The idea was somewhat "hot", no pun intended, when there was a silicon shortage going on, but silicon prices have dropped as new capacity has come online and the only successful CPV concepts being marketed which I know of are based on triple junction Ge/GaAs/InGaP or similar cells. These are also rather heat sensitive, and the two ...

  • A primogenius study on characterisation of c-Si solar cell

    The use of solar photovoltaic (PV) as distributed energy resources is increasingly being pursued as a supplement and alternative to conventional grid electricity. It has become an important source of energy because of its high reliability, requirement of very little maintenance and capability of generating power with no noise and emissions. Silicon solar cell as renewable energy resource has ...

  • UE: risk of shortage for 8 rare earth metals

    In a report published on November 4th, the European Joint Research Centre (JRC) has warned of the "risk of shortage" in 2020-2030 of eight strategic metals used in low carbon energy technologies identified in the European SET Plan adopted in 2008. This report continues the work done in a previous study of the JRC from 2011. It is also based on the scenarios presented in 2011 in the roadmap of ...

  • For cheaper solar photovoltaic systems

    It is known for several decades, photovoltaic devices that exploit the sun's energy to convert into electricity used to provide a sustainable alternative - and potentially unlimited - the use of fossil fuels. So why these solar technologies have they not been adopted more widely? Simply “because they are too expensive," said Ji-Seon Kim, professor of Solid Physics at Imperial College of ...
