Solar panels usually work through absorption. Light creates heat and, in turn, that heat is converted to energy. But physicists have long known that light has a magnetic element that, for years, has been ignored for being too weak to measure.
Students at the University of Michigan, however, have found that light’s magnetism can be captured and used without absorption, creating an intense charge. → Read More
Sharp Japan announced today it has developed a solar cell with the world’s highest conversion efficiency [press release in English]. The new product features an conversion efficiency of 35.8%, while Sharp only achieved 31.5% with the previous model. The latest model is a compound solar cell, in which two or more elements form photo-absorption layers (see the graphic below). → Read More
Sanyo added a few new products to its successful eneloop brand of “green” electronics today [JP], i.e. a hand warmer, a battery-powered and extra-warm blanket and a neck warmer. The coolest new product is the eneloop portable solar, a portable solar panel that’s sized at 174(W)×204(H)×26(D)mm. → Read More
It was just a matter of time, but frankly speaking, I am amazed at how fast Sharp makes its mini solar panel (67.5 x 41.0 x 0.8 mm) available to manufacturers worldwide [link in English]. After all, the company’s solar-powered cell phone that uses the so-called LR0GC02, isn’t even on sale yet (not even in Japan where sales start next month). → Read More
It looks like Sharp is seeing its (near) future in LCD TVs and solar panels. The company tomorrow sets up Sharp Display Products Corporation (SDP), a subsidiary based in Osaka. In addition, Toshiba will be partnering with Sharp to step up production of solar panels. The picture shows a solar-powered LCD TV Sharp showcased in July last year. → Read More
Tokyo-based electronics company OTAS is selling a lithium-ion battery for the iPhone 3G that comes with an integrated mini solar panel [JP]. The so-called LC-1500 is housed in a leather case. OTAS says one charge with solar energy takes 13 hours whereas charging the battery via mini USB takes 3 hours. The device measures 125x64x25mm and weighs 100 grams. OTAS is selling it in Japan only (price… → Read More
It seems Japan is getting greener every day. Now Buffalo announced they will start selling a wireless keyboard [JP] powered by solar energy from next week. The BSKBW01SB will be priced at $120. The 2.4GHz wireless device features a small solar panel located above the numerical keyboard block and can alternatively be powered using 2 AAA batteries. → Read More
