Abstract

Ohmic contacts of power AlGaAs/GaAs-based photovoltaic converters were studied, and a technique for their fabrication was developed. Effect of the doping level of the contact layer on the free-carrier density and the contact resistivity was examined. A technique for fabrication of 2- to 4-μm-thick ohmic contacts with electrochemical deposition of gold layers was studied. The effect of deposition modes on the surface morphology of ohmic contacts and their solidity and conductivity was revealed.
