Segregation preference of the impurity atoms at GB was determined with the help of calculations of segregation energy. It turned out that Al, Ga, In, Sn, Sb and Te preferred the substitutional positions and Si, P, S, Ge, As and Se the interstitial positions. The computational tensile tests considered two distinct approaches. One of them conformed to a separation of rigid grains simulating thus brittle cleavage slony a defined cleavage plane. The other approach was computationally more demanding since it also includes the Poisson contraction and full relaxation of the lattice. This model corresponds to the optimised uniaxial loading. The difference between computed strength values for both deformation models demonstrates that the choice of deformation model can play a crucial role in predicting the effect of impurities at GBs.
