    Neonsee offers customized sun simulation solutions exceeding Class A requirements. Neonsee unique system architecture enables the continuous adjustment of light intensity over the entire intensity range (0-120%) while remaining compliant with Class A requirements with regard to spectrum, homogeneity and intensity stability as per IEC 60904-9 and ASTM E 927. We offer customized features including automated intensity control and user defined spectral output.

IV and QE Measurement

  • Solar Cell Analysis Systems
    The current-voltage (IV) characteristic of a solar cell is an essential performance metric. While flash tester solutions provide the necessary data for cell binning in production environments, steady-state illumination measurements provide a greater range of possibilities. The flexibility to conduct measurements under in wide ranges tunable illumination, electrical and temperature conditions is the key to state-of-the-art measurement and analysis methods. neonsee‘s highly integrated turn-key IV test solutions offer full control of this parameters, all programmable by intuitive software, facilitating comprehensive IV derived loss analysis of solar cells.

LED based Solar Simulator

  • LED based Solar Simulator
    The device’s LED technology enables near-perfect solar cell efficiency measurement. Until now, xenon lamps were the standard light source for measuring solar cell performance. But they frequently deviated from standards by as much as 25%. The SINUS-220, however, exhibits a maximum error of only 2%. The 18-color LED-based light source is what makes this exceptional accuracy possible.
