Energy and electronics

In the ”Energy and electronics” business unit the work of the institute concentrates on the following developments:

  • Functional coatings or coating systems and coating processes for architectural glass (low-E coatings, active or passive heat and sun protection, switchable electrochromic glazing)
  • Transparent conductive coating systems (TCOs) for architectural and automotive glazing, for solar cells, displays and invisible heating elements and also for solar thermal energy
  • p- and n-type TCOs as materials for transparent and flexible electronics
  • Semiconductor layers for thin film and silicon-based photovoltaics and also characterization methods for thin-film solar cells
  • Electrical contact and insulating layers, as well as barrier layers
  • (Local) plasma treatment of surfaces for wafer bonding, structured metallization and metallization of temperature-sensitive and complexly shaped substrates
  • Stable anodes and cathodes for lithium-ion batteries
  • Energy storage systems
  • Electrolytic coatings for high-temperature fuel cells (SOFC) and gas separation membranes for hydrogen production
  • Corrosion-protection and thermal-barrier coatings for high-temperature applications, such as in gas turbines

Our customers include companies in the glass, photovoltaics and automotive industries, in semiconductors and microelectronics, in the information and communications sectors, in the energy and construction industries, and also plant manufacturers and contract coating companies.
