The outdoor measurements of both a single-cell and a 4-cell CPV modules reaching, respectively, maximum peak efficiencies of 36.0% and 34.8% (both corrected @Tcell=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 a Fresnel Köhler(FK), which is an advanced nonimaging concentrator using 4-channel Köhler homogenization, based on a primary Fresnel lens and a free-form secondary glass lens. Solar Junction's cell is a triple-junction solar cell with the A-SLAM{trade mark, serif} architecture using dilute-nitrides
