INFLUENCE OF INITIAL STRESSES ON THERMAL RESIDUAL STRESSES AND PEELING INTERNAL FORCES OF A SOLAR PANEL DURING THERMAL CYCLING

摘要：

　　Solar cell is a laminated structure with multilayer bonding.During the packaging/service process, the thermal cycling results in the residual stresses in the interior zone and the peeling internal forces at the edge interfaces, which reduce the service life of solar cell.To elucidate the destruction mechanism of solar panels, first, Zhangs two-variable method was used to establish an analytical formula for the axial normal stresses and the peeling internal forces.Second, the initial stresses and the peeling internal forces during the cooling process were analyzed.The present analytical predictions were compared with the Rus analytical predictions and the finite element results for a bilayered laminate.Third, the influences of low-temperature treatment and thermal cycling on the residual stresses and peeling internal forces of the bilayer with initial stresses were discussed.Some optimization suggestions were given at the final.
