Proceedings ArticleDOI
Commonly observed degradation in field-aged photovoltaic modules
TL;DR: In this paper, the authors define observed degradation in field-aged photovoltaic modules, including degradation of packaging materials, adhesional loss, degradation of interconnects, degradation due to moisture intrusion, and semiconductor device degradation, and suggest that the onset and progression of degradation need to be studied to gain a more comprehensive understanding of module degradation rates and module failures.
Journal ArticleDOI
History of accelerated and qualification testing of terrestrial photovoltaic modules: A literature review
Carl R. Osterwald,T. J. McMahon +1 more
TL;DR: The intent and history of these qualification tests, provided in this review, shows that standard module qualification test results cannot be used to obtain or infer a product lifetime.
Proceedings ArticleDOI
Degradation analysis of weathered crystalline-silicon PV modules
TL;DR: In this paper, the authors present an analysis of the results of a solar weathering program that found a linear relationship between maximum power degradation and the total UV exposure dose for four different types of commercial crystalline Si modules.
Journal ArticleDOI
Electrochemical corrosion of SnO2:F transparent conducting layers in thin-film photovoltaic modules
TL;DR: In this paper, a degradation mechanism in thin-film photovoltaic (PV) modules activated by damp heat and voltages similar in magnitude to those generated by PV modules in power generation systems was reported.
Journal ArticleDOI
Generalized Optoelectronic Model of Series-Connected Multijunction Solar Cells
John F. Geisz,Myles A. Steiner,Iván García,William E. McMahon,Carl R. Osterwald,Daniel J. Friedman +5 more
TL;DR: In this article, a general 1-D model to describe luminescent coupling that arises from both voltage-driven electroluminescence and voltage-independent photoluminecence in nonideal junctions was presented.
