Towards 25% efficiency solar cells: modelling and controlling defects in zone silicon

Project Details


The main objectives of the projects:

1. To develop a software for computer simulation of grown-in vacancy defects and impurities formed in monocrystalline silicon grown by float zone technique.

2. To establish a correlation between impurities and vacancy typedefects and carreier lifetime which is the key material parameter for solar cell silicon.

3. To provide input for control of the distribution of impurities and grown-in vacancy defects in monocrystalline float zone silicon in order to optimise carrier liftetime and solar cell efficiency.
