Perovskite Evaporation Systems
Perovskite solar cells are among the most promising technologies in modern photovoltaics. Thanks to their unique crystal structure and the ability to tailor their optical properties, they enable highly efficient next-generation solar cells. In particular, tandem cells combining perovskites with silicon or CIGS can utilize a significantly larger portion of the solar spectrum than conventional technologies.
A key advantage of perovskites is their extremely thin layers of only a few hundred nanometers. This reduces material consumption and production costs while simultaneously achieving very high conversion efficiencies.
For the precise vacuum deposition of sensitive perovskite materials, MBRAUN offers the specially developed MINI-PEROvap and PEROvap systems. A key highlight is the innovative cooling concept of the vacuum chamber, which minimizes cross-contamination and reduces unwanted material re-evaporation inside the chamber. This creates stable process conditions for reproducible, high-quality coating results.
