Photovoltaic keyboard

A photovoltaic keyboard, or solar keyboard, is a wireless computer keyboard that charges its batteries from a light source such as the sun or interior lighting, addressing a major drawback of wireless computer peripherals that otherwise require regular replacement of discharged batteries.

One such device is the Logitech K750, which was announced by the company in 2010. In 2018 Microsoft filed a patent describing how solar panels could be used to extend battery life for Microsoft's Surface Pro.
