Very High Efficiency Solar Cell (VHESC) program is developing integrated optical system-photovoltaic modules for portable applications that operate at greater than 50 percent efficiency. We are integrating the optical design with the solar cell design, and we have entered previously unoccupied design space. A test bed for rapid development and verification of performance of subsystems is also being developed. The results and analysis of the first complete integrated optics and ...
This paper reports the results of an international measurement round robin of monolithic, triple-junction, GaInP/GaAs/Ge space solar cells. Eight laboratories representing national labs, solar cell vendors and space solar cell consumers, measured cells using in-house reference cells and compared those results to measurements made where each lab used the same set of reference cells. The results show that most of the discrepancy between laboratories is likely due to the quality ...
