Beschreibung
A set of 15 thermomechanical design rules is derrived to support and accelerate PV module developments.
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 E ̂_α is introduced as a measure of how much thermal strain one material induces in another.
Stress in solar cells plays a crucial role in the reliability of photovoltaic (PV) modules. The influences on stress are as diverse as the number of different materials in a PV module and become more and more complex with the growing variety of PV modules for different applications. Within this dissertation, a set of 15 thermomechanical design rules is derrived to support and accelerate future PV module developments.
Three methods are developed and applied:
1. Thermomechanical finite element method simulations of PV module designs (FEM).
2. µ-Raman spectroscopy of laminated solar cells (µ-Raman).
3. Solar cell integrated stress sensors (SenSoCell®).
Furthermore, the concept of specific thermal expansion stiffness: E ^_a=E·a·A_j·h is introduced as a measure of how much thermal strain one material can induce in another.
