Production information

Quantum Efficiency Measurement System

IPCE-R 

IPCE-R Quantum Efficiency Measurement System is developed and designed in accordance with IEC 60904-8 to engage in the research and development of high-efficiency solar cells and improve the bandgap of their materials. Using non-destructive detection technology, the DUT can be directly measured without vacuum environment. In addition, its excellent signal-to-noise ratio and high-resolution signal acquisition capabilities provide fast and accurate measurement results. Compact design, easy to operate, high cost performance with excellent technical support, IPCE-R can also be integrated with the glove box according to customer needs which is suitable for various types of solar cells and photodetectors measurement.
