AI Technical Summary

Technical Problem

Traditional nitrogen glove boxes cannot effectively remove organic solvent atmospheres during the fabrication of perovskite solar cells, and their limited temperature and humidity control leads to disordered thin film crystal orientation, affecting device efficiency. In addition, nitrogen cleaning is costly.

Method used

The device employs a multi-functional temperature and humidity controlled air glove box, which combines a first heat exchange mechanism, a second heat exchange mechanism, and a rotary dehumidifier to create a low-temperature and dry environment. Through a circulating dehumidification and directional exhaust gas system, it achieves efficient removal of organic solvent waste gas and flexible control of temperature and humidity.

Benefits of technology

It significantly reduces dependence on nitrogen, lowers operating costs, and enables temperature and humidity control within the glove box in a low-temperature, dry environment, making it suitable for the fabrication of perovskite solar cells and improving device efficiency.
