New Technologies from the Renewable Energy Sector
With our work in the renewable energy sector, we in the Renewable Energy team are making a contribution towards modern climate protection and securing the energy supply of the future. Green is written with a capital "G" here.
With experienced experts from science, industry, and banking, interesting new technologies are being identified and analyzed and the existing technologies in the portfolio are being further developed and marketed.

Electrochromic laminated glass
- The light transmittance of the laminate panes can be set to any value between 8% and 75%.
- High transmission in a decolorized condition, due to lower amounts of tungsten oxide
- Switching behavior also in the near infrared range – the total energy transfer ratio (amount of heat in incident light) can be changed
- Layer production through electrochemical deposition from aqueous solutions
- Extremely low manufacturing costs

Flexible thin-film solar cell
- The patented thin film solar cell is comprised of semiconducting layers, which are applied to both sides of glass/carbon fibre fabrics by means of spraying.
- Application of the semiconducting layers by means of spraying cyclopentasilane under noble gas atmosphere
- Double-sided coating corresponds to the parallel switching of two cells
- Use of carbon fibres as contact

Metal catalysed recrystallisation of amorphous thin films
- The production of crystalline silicon thin films on inexpensive substrates, such as glass, is of fundamental importance for large size thin film solar cells. The patented titanium-supported metal-induced layer exchange process is a solution for the quick transformation of amorphous into polycrystalline silicon layers.
- Layer system: Glass/metal/metal oxide/a-Si
- Process: Anneal below the eutectic temperature | Duration: several seconds up to hours
- Result: Glass/poly-Si/metal/metal oxide

Solar panel in insulating glass technology
- Patented construction of solar thermal modules consists of an insulating glass compound in which an absorber sheet is integrated
- High thermal insulation through insulating glass construction
- Low heat transfer coefficient (k value) through special coatings
- Integration on roofs and facades

Solar-active coated thin films based on metal semi-conductor contact
- The novel production method (patent pending) exhibits low process complexity and enables inexpensive production of thin-film solar cells with a variable form factor.
- The wide band gap, UV-sensitive absorber is based on TiO2, and may be deposited onto commercially available glass substrates without vacuum or high temperature process steps.
- The technology enables production of PV modules with high optical transmission, which may be used e.g. as facade elements to address the emerging market of Building Integrated Photovoltaics (BIPV).
