On-sun performance of a novel microcell based HCPV system based in TUSCON and comparison with conventional systems

On sun performance data for a 1 kW HCPV RD&D system is presented. The HCPV modules are fabricated with transfer printed micro-cells that operate at a concentration of 1000 suns. This system, installed in Tucson, AZ, is the first field validation of this novel approach that addresses the cost, performance and reliability aspects of HCPV systems. The performance of the Semprius HCPV system is compared with that of alternative PV systems, also being tested at the same location. Finally, current developments on Semprius' technical roadmap are described.
