G24i collaborates with Logitech - world's first light-powered keyboard

G24 Innovations Limited (G24i), manufacturer of dye-sensitised photo-electric cells (DSC), has collaborated with Logitech, to create the world's first light-powered tablet keyboard folio. The Logitech® Solar Keyboard Folio for the Third-Generation Apple iPad® and iPad 2, announced by Logitech on May 3, 2012, represents the first major application of game-changing DSC technology in the consumer electronics space.
The ultra-slim folio delivers tablet protection and features a built-in Bluetooth® keyboard that is powered by any light, even lamp light. With no silicon components, G24i's DSC technology is lightweight, power-dense, robust and flexible; ideal as an integrated, portable and environmentally-friendly power source.
The two businesses have worked closely for over two years to deliver a product that liberates the customer from the burden of having to replace expensive and environmentally harmful disposable batteries. During this time, G24i has extended its record indoor light conversion to over 26% efficiency, rating its DSC technology as almost five times more powerful than its nearest competitor.
Last week in Berlin, the achievement was recognised as the 2012 Best Technical Development of an Energy Harvesting Device at the Energy Harvesting and Storage Europe conference.
Bracken Darrell, Logitech President commented, "We're excited about the Logitech Solar Keyboard Folio. This signals the future of small electronics. G24i is at the forefront of a whole new class of sustainable, self-powered products that don't need charging or replacement batteries. You buy them and they need nothing but light."
"G24i's record power density, together with the lightweight, robust and flexible profile of its cells, gives us confidence that advances in DSC technology can keep up with the demands of ever-more power hungry devices in the future."
"G24i and Logitech are proving that being green can also be about customer convenience, design excellence and cost effectiveness," commented Robert Hertzberg, Co-Founder and Director of G24i. "This is not a novelty product."
"This deal is an important milestone in the development of our business and its aim to displace disposable batteries with next-generation energy harvesting technology. The global market for disposable batteries is worth in the region of $80bn a year."
G24i's technology was developed at Ecole Polytechnique Fédérale de Lausanne (EPFL), where Logitech also has a long and proud history. Professor Graetzel's dye-sensitised cell invention is recognised as coming close to mimicking the light reaction in nature's photosynthesis.
"G24i has made my vision of mimicking nature's photosynthesis a commercial reality", commented Professor Michael Graetzel, recipient of the 2012 Albert Einstein World Award of Science and the 2010 Millennium Technology Prize for inventing Dye Sensitised Cells. "By leveraging a renewable energy source that is readily available, G24i and Logitech can change the face of consumer electronics. I anticipate that this is the first of a series of successful green products."
The Logitech Solar Keyboard Folio is expected to be available in the U.S. and Europe from May 2012, for a suggested retail price of $129.99.
About G24 Innovations
G24 Innovations Limited is the global leader in the manufacturing of next generation Dye Sensitised photo-electric Cells (DSC). G24i's disruptive technology has the potential to make disposable batteries obsolete with the recycling of ambient indoor light, even lamp light, to electricity. G24i energy harvesting technology will give birth to a new family of autonomous self-powering electronic devices. External Link
About EPFL
EPFL is one of Europe's most cosmopolitan technical universities. It receives students, professors and staff from over 120 nationalities. With both a Swiss and international calling, it is therefore guided by a constant wish to open up; its missions of teaching, research and partnership impact various circles: universities and engineering schools, developing and emerging countries, secondary schools and gymnasiums, industry and economy, political circles and the general public. External Link
About Dr. Graetzel
Professor at EPFL, Michael Graetzel directs there the Laboratory of Photonics and Interfaces. He pioneered research on energy and electron transfer reactions in mesoscopic-materials and their application in solar energy conversion systems, optoelectronic devices and lithium ion batteries. He discovered a new type of solar cell based on dye sensitized nanocrystalline semiconductor oxide particles. Author of over 900 peer-reviewed publications, two books and inventor of more than 50 patents, his work has obtained 88'000 citations so far (h-index 138), ranking him amongst the 10 most highly cited chemists worldwide.
