Wasted artificial light gets new life as electricity

In an office, or your home, what ever light does not pass through your eye gets wasted. A new photovoltaic technology based on Perovskite, better know as calcium titanium oxide, have been developed into PV that can capture artificial, indoor lighting, found inside buildings. The amount of energy in artificial lighting is much less than that in sunshine. However, these PV cells are able to capture enough energy to run small, low-power wireless sensors or remote-control units, eliminating the need for batteries and chargers.
