  • ILS-30_ Ambient Light SimulatorILS-30 is an indoor light simulator which can illuminate three different color temperature light illumination (3000K, 4000K, and 5500K). The light intensity can be continuously turned from 250 lux to 1000 lux, which covers the indoor ambient light intensity levels. ILS-30 provides an 100mm x 100mm beam spot. Within 50mm x 50mm beam area, the uniformity can better than 95%. It is easy to adjust the light intensity or color temperature. The size of ILS-30 is very compact and convinient to be install. ILS-30 can help you to quickly set up accurate indoor PV charaterization facility.

  • QE-RXQE-RX is a PV cell efficiency-loss analyzer for the high efficiency solar cell research and development. Since 2015, the loss mechanism is the key information for improving the conversion efficiency of PERC, HJT, TOP-Con and other highly efficient solar cells. The conversion efficiency loss can be attributed to three factors, including short-circuit current density (Jsc), open-circuit voltage (Voc), and fill-factor (FF) losses. QE-RX can not only measure the PV-EQE, Reflectance and PV-IQE data but also analyze Jsc, Voc, and FF losses by combining the analyzing software SQ-JVFLA.

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.
