Course content

The course will be given in spring 2017. The course will give a performance of the different structure elements of solar cells (contacts, doping, pn-junctions, etc.). 
Directional solidification and growth process. 
Precipitation and the effect of precipitates on material properties. 
Characterization of silicon wafers: 
- Preparation of wafers (polishing, etching, etc.). 
- Grain boundaries, grain size and grain orientations (SEM, EBSD. etc.). 
- Dislocation density measurements (Optical, PVScan). 
- Resistivity/life time measurements. 
- Chemical analysis (SEM, GDMS, FTIR) 
- Inclusions (Infrared microscopy, dissolution). 
Effect of microstructures on the effeciency of solar cells.
