  • SunnyBot Is A Solar-Powered Robot That Tracks The Sun To Reflect Sunlight Wherever You Want It

    SunnyBot Is A Solar-Powered Robot That Tracks The Sun To Reflect Sunlight Wherever You Want It

    Here’s a neat greentech idea currently seeking crowdfunding on Kickstarter. SunnyBot is a microcomputer-powered robot that continually tracks the position of the sun, angling its on-board mirror so that it keeps reflecting the sun’s rays onto a fixed point of your choice. The basic idea being to harness solar energy for use as an indoor light-source when rooms might otherwise be… Read More

    Sharp Reaches Record Conversion Efficiency With New Solar Cell

    Solar energy has just made one step forward: Sharp announced that it has developed a solar cell boasting the world’s highest conversion efficiency of 36.9%. This number is 1.1 points higher than for the company’s last cell, which was unveiled in October 2009. The new 1cm2 solar cell consists of three layers made of indium gallium phosphide, gallium arsenide and indium gallium… Read More

    The Long Hard Road To The Edge

    A Year In The Life Of An Entrepeneur 1. July 2010: Ready: Set: Delaware, the state with the lowest highest point. David Argentar, a biochemist by training and bioinformaticist by trade, has launched a startup. Of sorts. Well – more of a hobby, he’d be the first to admit. He has no business plan, no investors, no employees. All he really has, in fact, is an idea and a pending patent. Read More

  • Europe And Japan Collaborate To Develop World’s Most Efficient Photovoltaic Cell

    Seeing solar energy progress is a good thing, but it still has one problem: at this point, it’s still inefficient when compared with other sources of energy. And now Japan and Europe have announced [PDF] that they will work together to develop the world’s most efficient photovoltaic cell over the next four years. Read More

  • Mitsubishi Chemical To Commercialize Printable Solar Cells Next Year

    Another small step ahead in solar energy: Mitsubishi Chemical has developed printable solar cells with a conversion rate of 9.2% and now plans to commercialize the cells as early as next year, according to Japanese business daily The Nikkei. Read More

  • Purdue Research Cracks Both Of Solar Energy's Roadblocks, Road Opens In 2013

    Whenever I overhear conversations on the environment, the common consensus is always, “why don’t they just put solar panels everywhere?” As much as that would be the most optimistic scenario, there have been and still are some serious road blocks to widespread solar panel use: efficiency and cost. The theory of lowering cost is easy. Increase production efficiency, and panel… Read More

  • Video: Retractable, Portable Solar Power Unit

    Solar energy is progressing: Japan-based OS has developed the so-called “Mobile Solar Unit” [ENG, PDF], which is essentially a portable power generation system that comes with a retractable solar panel. The system can provide a total of 40W of power, 16W from the solar sheet and 24W from a built-in battery. Read More

  • New Tech Reduces Production Costs Of Solar Cells By Up To 70%

    The Japan Advanced Institute of Science and Technology (JAIST) has made a step forward in solar energy. The institute says that in cooperation with Toshiba and chemical company JSR, it has developed technology [JP] that makes it possible to slash productions costs of solar cells by up to 70% when compared to existing methods.

  • Sanyo To Mass-Produce World's Most Efficient Solar Cells

    Yesterday, we reported that Sharp is ready to invest $180 million in a new plant near Osaka to mass-produce solar cells. And now, just 24 hours later, we have yet another positive news item from the green energy front: Sanyo today announced it will start mass-producing a new type of solar cell, too. Read More

  • Sharp To Start Mass-Producing Efficient Solar Cells

    Back in September, Sharp made headlines when the company showed the world’s most efficient solar cell, a prototype that can convert 42.1% of sunlight into electricity. Yesterday, the company announced it will start mass-producing a new type of solar cell at its Sakai City plant in western Japan, with a total investment of $180 million. Read More

  • Sharp Sets New Record For Solar Cell Efficiency

    If there’s something solar energy as a technology needs, then it’s better and cheaper solar cells. And now Sharp has apparently made a step forward regarding the first factor: the company says it has developed a solar cell that has the world’s highest efficiency of 42.1%, breaking the record of Spectrolab of the US.
