UK firm touts solar without sunlight technology designed to replace batteries in consumer electronics

Powering smart phones such as iPhones with solar technology has moved a step closer, after a UK company set a new record for converting indoor light into electricity.

Cardiff-based G24 Innovations (G24i) claims to have produced a photovoltaic (PV) cell with an efficiency rate of 26 per cent, beating the previous record, also held by the company, by over 10 percentage points.
