Gloveboxes for Perovskite Cell Manufacturing
Perovskite Processing Under a Controlled Atmosphere
Perovskite solar cells are considered one of the most promising next-generation technologies in the photovoltaic industry. They offer the potential for significantly higher efficiencies, lower manufacturing costs, and flexible applications, ranging from conventional modules to novel lightweight and flexible surfaces.
At the same time, perovskite materials place high demands on the process environment. Many of the organometal halide perovskites used are sensitive to oxygen and moisture while also containing toxic and corrosive components. A controlled inert gas atmosphere is therefore essential to ensure stable and reproducible manufacturing processes.
With specialized glovebox and process solutions, we enable the safe processing of sensitive perovskite materials, from research to industrial production.
Potential of Perovskite Technologies
Perovskites open up new possibilities in photovoltaics and beyond:
- High conversion efficiency combined with low manufacturing costs
- Simple and versatile processability
- Coating possible on flexible and structured substrates
- Use of cost-effective and readily available materials
In addition to solar cells, perovskites are also used in light-emitting diodes (LEDs), lasers, sensors, and many other applications. This versatility makes them a key technology for future optoelectronic applications.

Coating Technologies for Perovskite Layers
Perovskite layers can be produced using different methods:
Wet Chemical Methods (Solution Processing)
- Processing under ambient or controlled conditions
- Simple and cost-efficient manufacturing
- Commonly used in research and development
- Compatible with a wide range of commercially available coating methods
Gas Phase Processes (Vacuum Deposition)
- High film quality and precise process control
- Suitable for precise and reproducible applications
- Higher requirements for process equipment
Hybrid Processes
- Combination of wet chemical and vacuum-based processes
- Combine the advantages of both methods
- Increasingly relevant for industrial applications
Process Challenge and Innovative Solution: PEROvap
A particular challenge in the vacuum deposition of perovskites is the handling of materials with low boiling points, such as methylammonium iodide. These materials tend to re-evaporate even at room temperature, making the formation of stable and reproducible layers considerably more difficult.
Our Solution: MBRAUN PEROvap
With the patented PEROvap process, MBRAUN offers a platform specifically developed for the stable and controlled deposition of such materials. It enables reproducible processes and opens new possibilities for the industrial application of perovskite technologies.
