- Growth of crystalline silicon on amorphous substrates
- Preparation of precursors for CIGS microconcentrator solar cells
Technical Info
MAIN FEATURES:
The mission of the Institute is to perform basic and applied research in the fields of growth, characterization and processing of crystalline matter and to fulfil service tasks for partners and customers in industry and science.Main PV RTD tasks of the Institute are
- growth of crystals with dimensions between decimeters and nanometers
- development of growth and processing technologies
- characterization of crystals and development of methods for characterizing them
- design and construction of components for growth, processing and characterization facilities
IKZ-Si/Ge Nanocrystals Research group involved in CHEETAH project is focussed on:
Silicon on glass
- Low-temperature growth of silicon layers from metallic solutions
- Application of amorphous substrates (glass) as precondition for cost-saving solar cells
- Well-defined production of silicon seed layers by amorphous-crystalline phase transition (ALC) catalyzed by liquid metallic droplets
- Structural and electrical characterization both of seed and crystallite layers
Si/Ge nanocrystals
- Vapor-liquid-solid (VLS) growth of nanowires under UVH conditions
- Thermodynamics of liquid solid phase transition and investigation of the growth kinetics of nanowires
- Predefined localization of growth sites of nanostructures by local anodic oxidation (LAO) or focused ion beams (FIB)
- Embedding of nanostructures within hydrogen silsesquioxane (HSQ) and epitaxial overgrowth starting from uncovered parts of such nanocrystals
