This combination iPad case and keyboard from Logitech uses a photovoltaic technology called dye-sensitized solar cells, which are highly efficient at producing electricity from indoor light. The photovoltaic cells recharge an onboard battery that provides power to the keyboard—which is part of the case that protects the iPad. These cells are made by G24 Innovations in Cardiff, Wales, based on technology originally invented in 1991 by Michael Grätzel at the Swiss Federal Institute of Technology in Lausanne, Switzerland.
