No chopper or order sorting filters are required thus making the system more affordable.

A monitor cell is used use in every scan to assure data accuracy and reproducibility. Use the included reference cell for specular reflectivity measurement to obtain an IQE estimate. The included DC mode electronics and completely dark enclosure allow QE metrology on organic cells and other slow response materials. Computer controlled multi-colour bias lights and voltage bias option allows multi-junction cells biasing. System design flexibility allows testing of a wide variety of cell types. A partial listing includes: poly silicon, c‐Si, mc‐Si, nc-Si, III-V compound cells; thin film: Perovskites, CdTe, CIS, CIGS, SI; 3rd generation: organic polymer, dye. XY scan and multiplexer options offer automated EQE map generation or multiple devices scanning.
