The left-hand image shows a silicon carbide nanocrystal and the right-hand image presents a silicon nanocrystal, together with the indices for grid planes.

Tandem Solar Cells on Crystalline Silicon

R&D Services

Our R&D services comprise:

Si-based tandem solar cells

To make better use of the whole solar spectrum (reduction of thermalisation losses), we are also developing silicon-based tandem solar cells. In addition to process adaptation for the Si base cell and the development of tunnel contacts, our research is concentrating primarily on new silicon nanocrystalline materials with adjustable band gaps and III-V-based absorber materials. The two sub-cells are combined either by direct stack growth on the Si base cell or by wafer-bonding.
