PeroTec – Scalable Perovskite Technology

The production, functionality, and in particular, the service life of perovskite systems as well as their interdependencies have not yet been sufficiently researched, optimized, nor developed as marketable implementation. Currently, perovskite elements can only be realized in the lab with dimensions in the square centimeter scale and are not yet stabilized. A current weakness is the lack of suitable sealing materials and application technologies as well as scaling to formats in the square meter range.

In the “PeroTec” Fraunhofer project, the technological prerequisites for applications in the square meter range should be established and patent-protected for the industrial use of novel perovskite materials. As common feature, these perovskite materials crystallize as salts with the “perovskite” structure type and are, e.g., active with respect to photovoltaics. Due to their chemical nature, these salts are hydrolysis and oxidation-sensitive and react to electrical potential differences. With that, the core task of the project is to integrated and electrically contact these materials with large-scale protection against water, oxygen and ion drift in the component. The technological solutions to be developed in the project will then represent the basis for a future perovskite technology.

The objective and the service offering to be developed in the project are:

1. The provision of newly developed process steps and novel materials as well as system properties (based on material development and modeling)     
   
2. Patent applications for royalty income
3. Realization of a photovoltaically effective demonstrator suitable for the mass market
4. Development of permanently usable perovskite systems, evaluations and analyses, long-term behavior and reliability
5. Perovskite competency overview and development at Fraunhofer
