New miniature sized dye solar cell technology developed by an Israeli company can be installed onto devices and charge them with indirect light, making batteries obsolete. Sharon Reich reports.
These little glass squares could just be the answer to charging all your electronics. The glass-printed photovoltaic cells are a form of Dye Solar Cell technology created by Israeli company 3G Solar Photovoltaics. They're so sensitive they can generate power from indirect, indoor lighting. Check it out. The company's head of R&D Nir Stein is taking the batteries out of this mouse, which has the company's dye solar cell module installed on top. NIR STEIN, DIRECTOR PRODUCT R&D AND CHIEF BUSINESS DEVELOPMENT OFFICER AT 3GSOLAR PHOTOVOLTAICS SAYING: "What you see here is a computer mouse that has a bluetooth connectivity inside it and is powered by 3G solar photovoltaic cells. So when you have thousands of sensors, for instance in a building, which is going to happen in the next few years, you'll never have to change a battery again." Dye-sensitized solar cells, or Graetzel cells, were discovered about 20 years ago. When they're exposed to sunlight the dye becomes excited and creates an electronic charge without the need for pricey semiconductors. Kind of like the way plants use chlorophyll to turn sunlight into energy through photosynthesis. While the technology is the same, 3G Solar Voltaics' CEO Barry Breen says that being able to embed the cells on small surfaces has the potential to change the way we charge everyday devices. (SOUNDBITE) (English) BARRY N. BREEN, CEO OF 3GSOLAR PHOTOVOLTAICS, SAYING: "What we offer in our cells, in our light power devices, is a solution that gives three times the power of anything else that exists, and we're talking indoors, where most the electronics are used. So three times the power to run these new electronics, the new sensors, the smart watches and other wearables. So it's a way to keep those powered that couldn't be done before." The small modules are durable and last for about 10 years. They can be colored and fitted to the shape of a device so they don't stand out. Although still a prototype, the makers say the technology could make batteries a thing of the past.
