Development and characterization of an FK photovoltaic concentrator for maximum conversion efficiency

摘要

The outdoor measurements of a single-cell concentrator PV module reaching a regressed 35.6% efficiency and a maximum peak efficiency of 36.0% (both corrected @T_(cell)=25°C) are presented. This is the result of the joint effort by LPI and Solar Junction to demonstrate the potential of combining their respective state-of-the-art concentrator optics and solar cells. The LPI concentrator used is an FK, which is an advanced nonimaging concentrator using 4-channel K?hler homogenization, with a primary Fresnel lens and a refractive secondary made of glass. Solar Junction's cell is a triplejunction solar cell with the A-SLAM~(TM) architecture using dilute-nitrides.
