New monolithic multi-junction cell concepts with more than three subcells are a challenge for a precise light IV-curve characterization. The available sun simulator tools are not suitable for the characterization of these devices. Therefore, a new six channel sun simulator was set up to measure and characterize monolithic solar cells with up to six subcells. This paper presents main benchmark data of the new simulator, like uniformity and spectrum. Calibrated light IV-curves of four- and six-junction solar cells are shown.
