Investigations on the recombination activity of grain boundaries in mc silicon (2008)
Zuschlag, A., Micard, G., Junge, J., Käs, M., Seren, S., Hahn, G., ...
This paper focuses on the limitation of the effective intra-grain minority charge carrier diffusion length and surface recombination velocity at grain boundaries. Both can be extracted in principle...
Fast illuminated lock-in thermography: An inline shunt detection measurements tool (2008)
Seren, S., Hahn, G., Demberger, C., Nagel, H.
This paper focuses on the fast spatially resolved detection of material and / or processing induced shunting using fast illuminated Lock-In Thermography (iLIT). With this technique shunting can be...
Junge, J., Käs, M., Grötschel, D., Zuschlag, A., Seren, S., Hahn, G., ...
In the past few years the quality of Edge-defined Film-fed Growth (EFG) material has strongly improved and can now compete with most standard multicrystalline materials. The maximum conversion...
