Quantum efficiency measurement system

• Module (QE-R) and Company (ENLI TECH), Location (Optical Room 2)

    Superuser (Yan GAO), contacts (15926498386)

• Brief description: It is primarily designed for measuring the EQE and IQE of solar cells and analyzing their spectral response. It not only characterizes the cell's ability to absorb light across the solar spectrum but also provide the critical information such as the diffusion length and the minority carrier lifetime. The system is suitable for various devices, including perovskite, organic, and single-junction or multi-junction solar cells.
