In this paper, we present the results of a combined theoretical, computational and experimental study of failure mechanisms in model multilayers that are relevant to stretchable organic solar cells. The deformation of these structures is elucidated under monotonic loading that simulates possible stretching phenomena. The stress distributions within the layers and the possible interfacial crack driving forces are computed for model layered structures with well controlled thicknesses and elastic properties. The implications of the results are discussed for the improved design of stretchable organic solar cells with reliable optical properties.
