Ultra high efficiency HCPV modules

Semprius manufactures HCPV modules and systems. Module characterization and QC methods are described in this paper. Module efficiency distribution for thousands of modules is presented, showing an increase in average efficiency from 33.2% in 2013 to 34.9% currently. Data from modules and systems in the field is presented showing no measureable degradation after three years and consistent performance over different seasons. Finally, the effect of ambient temperature and wind speed on performance was studied.
