Abstract

In this paper, the influence of pre-existing crystalline damage, such as cracked or broken
cells or soldering failures, as they are frequently observed in operating photovoltaic
(PV) plants, on the degradation behavior of mono- and polycrystalline silicon
PV modules is investigated. In particular, it is analyzed if and to what extent predamage
introduced prior to lamination propagates upon stress exposure. Therefore,
the pre-damaged modules are exposed to various accelerated aging conditions in
order to analyze the impact of the pre-damage on the degradation behavior under the
respective aging scenario. In order to separate the influence of the pre-damage from
composition-induced influences, the choice of materials used in the modules is varied.
These investigations reveal that none of the accelerated aging tests causes any
change in the pre-existing damage. In fact, the degradation behavior and rate rather
depended on the choice of the module components than on the nature of the predamage.
Finally, these results are compared with indoor and outdoor results obtained
from other studies
