Contribution to the Modeling of Ageing Effects in PV Cells and Modules

In this paper, we present an overview of three degradation modes: the Potential Induced Degradation, the Light Induced Degradation, and the Ultraviolet Light Degradation. Then we develop a mathematical model that describes the latter degradation modes in order to evaluate the lifetime of PV (photovoltaic) modules. At the end we simulate the efficiency of a PV module as a function of time where the three degradation modes are taken into consideration.
