A research team at George Washington University has developed a prototype solar cell that integrates multiple layered cells stacked into a self-contained device capable of absorbing nearly all of the energy in the solar spectrum.
The new design that converts sunlight to electricity at 41.2% module efficiency and 44.5% implied cell efficiency could prove to be the most effective solar cell ever produced, but is quite an expensive prototype.
Last year UNSW demonstrated a 34.5% efficiency record for a novel cell design.
