Silicon solar cells play a crucial role in Photo voltaic (PV) application. We have numerically investigated thermal stress and normal stress components (Sigma 11, Sigma 22, Sigma 33 and sigma 12) by using finite volume method. The maximum thermal stress has low value at the centre region for 900 K and 700 K annealing temperatures comparing all the cases. The maximum thermal stress at peripheral region is low for 700 K annealing compared to 900 K annealing. The annealing effect of me-Si ingot normal stress components is discussed. At 700 K annealing temperature the normal stress in 11 and 33 direction has lower maximum and at the 900 K annealing temperature the normal stress in 22 and 12 direction has lower maximum.
