The perovskite cell cyclic exposure testing system can simulate damage caused by full-spectrum sunlight, temperature and humidity changes, and can replicate outdoor aging effects for months or even years within days or weeks. It can provide corresponding environmental simulations and accelerated testing for scientific research, product development, and quality control.

Product Features and Advantages:

1. A very simple user interface for quick results

2. Uses a unique light intensity feedback system with excellent light intensity stability (within ±2%), with a temperature range of 20 to 90°C

3. Temperature accuracy can be within the ±1°C range, and between 20 and 90°C. ± 0.5°C ranges from 25 to 60°C.

4. The constant temperature chamber is equipped with a BNC connector for constant temperature I-V measurement

5. The observation window allows you to observe samples in a temperature-controlled room without opening the door.

6. Capable of dual 85 testing, 85% humidity, and 85°C long-term aging tests.

7. Capable of long-term testing for 15,000 hours without the need to replace the lamp source

8. The bottom of the aging chamber chamber uses a drainage groove design to prevent steam condensation and maximize protection of the test workpiece.
