Abstract
A theoretical conversion efficiency of 36.4% at 1000 suns concentration has been determined by means of realistic models and an improved optimization routine. The starting point device was the recent world-record monolithic GaInP/GaAs dual-junction solar cell that was grown lattice matched on a GaAs substrate by MOVPE, which has an efficiency of 32.6% at 1000 suns. Using previously calibrated models developed at our institution, IES-UPM, together with Silvaco ATLAS TCAD software, we reproduced the characteristics of the world-record solar cell, and then determined a cell configuration that would yield greater efficiency by using an optimization routine to hone the doping concentration and the thickness of each layer.
