  • 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 ...

  • 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 ...

  • Start-up of first 100 kw system in Shanghai with 3-sun PV Mirror modules

    ABSTRACT Thanks to funding from the Shanghai City government, Shanghai Import Export Trading Company, and Shanghai Flower Port, we have designed and fabricated in pilot production the first 3-sun 180 W (STC) mirror panels. Three of these panels were first tested in the US showing calibrated PTC ratings of 150 W. Then 24 panels were installed on two 2-axis trackers at the Flower Port in ...

  • Demonstration of a 33% efficient Cassegrainian Solar Module

    Abstract The Cassegrainian solar concentrator module concept we shall describe here uses a primary and a dichroic secondary mirror to split the solar spectrum into two parts and direct the infrared and near visible portions of the spectrum to two separate cell locations. An efficiency of 32.9% (STC) is reported measured outdoors for a solar concentrator PV module using InGaP/GaAs dual ...

  • 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 ...
