We characterized InGaAsP solar cell devices using electrolytic gold plating as surface electrode under 1064 nm laser irradiation. The increase in the electrode thickness was confirmed to reduce the deterioration of the fill factor and improve the power conversion efficiency under high laser power irradiation.
