There are more details coming out over the Wysips Solar Powered screen for smartphones we reported on last week. According to this hands on, done by Laptop Magazine, the photovoltaic screen will be included in new smartphones within a year and promises to only add about $1 to existing cellphone prices. The hands on shows a smartphone mockup with an amp-meter attached to it, showing the fluctuating voltage as the device moves in and out of exposed light. Wysips also says that the solar film isn't only being developed for for smartphones, it'll have applications for tablets and eBook readers as well.
