N2 - Chapter 3 deals with the role of impurities and defects on the electronic behaviour of silicon, as well as the methods to minimise their deleterious impact on PV devices. The key role of defect engineering is illustrated, with particular emphasis on thermodynamic and kinetic aspects of segregation and gettering.
