A Cyclic Exposure Testing System for Perovskite Batteries
The perovskite battery cycling exposure testing system can simulate the damage caused by full spectrum sunlight, temperature and humidity changes, and can reproduce the aging effect of several months or even years outdoors within a few days or weeks. It can provide corresponding environmental simulation and accelerated testing for scientific research, product development, and quality control.
Product features and advantages:
1. A very simple operation interface for quickly obtaining results
2. Using a unique light intensity feedback system, the stability of light intensity is excellent (within ± 2%), with a temperature range of 20 to 90 ° C
3. The temperature accuracy can be within the range of ± 1 ° C and within the range of 20 to 90 ° C. The range within ± 0.5 ° C is 25 to 60 ° C.
4. The constant temperature chamber is equipped with BNC connectors for constant temperature I-V measurement
5. The observation window can observe the sample constant temperature chamber without opening the door.
6. Can achieve dual 85 testing, 85% humidity and 85 ℃ long-term aging testing.
7. It can achieve 15000 hours of long-term testing without the need to replace the light source
8. The bottom of the aging chamber studio adopts a drainage groove design to prevent steam condensation and maximize the protection of the test workpiece.
