A photovoltaic keyboard, or solar keyboard,[1][2] 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.[citation needed]
One such device is the Logitech K750, which was announced by the company in 2010.[citation needed] In 2018 Microsoft filed a patent describing how solar panels could be used to extend battery life for Microsoft's Surface Pro.[3]
