A Simplified Model for Thermal Stress Analyses of Bi-Layers With Extreme Dissimilar Thermal Properties in Solar Cell

Abstract

This paper aims at developing a simplified analytical model, as verified by the Hilbert-Riemann theoretical solution of interfacial cracks, to study the thermal stress distributions in solar cell laminated structures under thermal loadings. The interface thermal failure problem is analyzed in terms of the packaging materials and solar cell materials of simulated models, maximum interfacial normal stress, and stress critical point. It provides some guidance for the design and optimization of solar modules.
