  • 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.

  • Solar industry creating jobs, not just juice

    It appears that there may be a recession proof industry after all. The Solar Energies Industry Association just released their annual report, and while coal and oil are “suffering”, solar is a growth industry. Read More

  • Thin, flexible "solar threads" to turn fabrics into power generators

    A Tokyo-based venture called ideal Star [JP] has developed a new method that makes it possible to produce solar cells in the form of flexible and thin threads. The company is supported by a total of six Japanese universities and the government. The current prototype cell is 5cm long and just 0.8mm in diameter. ideal Star says the core consists of polymer material and is surrounded by an… Read More

  • Sharp to bring solar-powered cell phone to China (and possibly elsewhere, too)


    Sharp, the biggest (in terms of market share) of all eight major Japanese cell phone makers, has been talking about internationalizing its phone business for quite some time now. It makes sense, as the domestic market is shrinking and as Sharp only sold 20% of all their cell phones outside Japan (1.6 million units) last fiscal. Read More

  • Panasonic ready to pump $1.1 billion into solar energy business

    There’s a reason why Panasonic paid $4.4 billion in this economic downturn to acquire former rival Sanyo, and the reason is that Panasonic wants to go as “green” as possible in the future. Sanyo isn’t only the world’s leading maker of lithium ion batteries, but also the (now former) company behind the eneloop brand, which consists of a range of eco-friendly… Read More

  • Sharp develops efficient solar cells for use in outer space

    Earlier this year, we reported twice about Japan’s serious plans to go to outer space to generate solar energy and then beam it back to Mother Earth. And today, Sharp has shown the first solar cell that’s not only bendable (we’ve seen that before) but that also withstands conditions in space. In addition, the company says those cells boast a record-high solar efficiency of 36%. Read More
