According to Fullsuns ©, their current “GaAs GaAs Solar Cell Technology” has a maximum conversion rate of 31.6%, and this value has been recognized by the National Renewable Energy Laboratory (NREL) as the world's number one conversion rate. Mechanical deformation of a nanowire (NW) solar cell can improve its efficiency. Solar cells with energy bandgaps engineered for the optimal collection of photogenerated carriers have the potential to yield higher efficiencies than conventional cells.
