Three methods are developed and applied: 1. Thermomechanical FEM-simulations of PV module designs. 2. µ-Raman spectroscopy of laminated solar cells. 3. Solar cell integrated stress sensors (SenSoCell®). The concept of specific thermal expansion stiffness Êα = E · α · Aj · h is introduced as a measure of how much thermal strain one material induces in another.enPhotovoltaicsFinite Element MethodStressPhotovoltaic Module DesignRenewable EnergiesMechanical EngineeringDDC::600 Technik, Medizin, angewandte Wissenschaften::620 Ingenieurwissenschaftendoctoral thesis
