Power conversion efficiencies (how efficiently incident sunlight is converted to electrical power) in perovskite-based solar cells have increased from a starting point of 3.8% in 2009 to a staggering 19.3% by May 2014.

That is a significant increase in efficiency from the previous record of 10.1%. The new single-junction microcrystalline silicon solar cell had it’s record independently verified by the Fraunhofer Institute for Solar Energy
