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 arsenide (see… → Read More
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
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. → Read More
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
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
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. → Read More
Japanese companies Gunze and Dai Nippon Printing are each developing new technologies that make it possible to produce low-cost, pigment-sensitized solar cells. Gunze focuses on low-end solar cells that can be used to power smaller electronic appliances or in-store ad displays, for example. Their cells will use a film, which is coated with special pigments, as a power source. Gunze, actually a… → Read More
