The proposed DoE STTR project will provide a pathway for terrestrial CPV (500 to 700 Suns) multi- junction solar cells that will maintain extremely high efficiencies at realistic operating temperatures. The thrust of the proposed project will adapt an integration approach from MEMS to III-V materials grown lattice-matched to gallium arsenide substrates. The efficiency advantages were found to be substantially due to the 37% smaller temperature coefficient of efficiency for the proposed CPV cell. Based on NRELs System Advisor Model (SAM) software, the LCOE based on the proposed CPV cell technology at 630 Suns is 20.96/kWh (real) for a CPV cell with 45% efficiency and 20.22/kWh (real) for a CPV cell with 48.5% efficiency.
