Milestones Toward 50% Efficient Solar Cell Modules

摘要

The Very High Efficiency Solar Cell (VHESC) program is developing integrated optical system - PV modules for portable applications that operate at greater than 50 percent efficiency. We are integrating the optical design with the solar cell design, and have entered previously unoccupied design space. Our approach is driven by proven quantitative models for the solar cell design, the optical design and the integration of these designs. Optical systems efficiency with an optical efficiency of 93% and solar cell device results summing to 42.9% are described. Keywords: High performance, module architecture, solar cell efficiency.
