Workshop: Impact of mechanical and thermal loads on the long term stability of PV modules

(PresseBox) (Emmerthal, ) The Institute for Solar Energy Research Hamelin (ISFH) and the Institute of Structural Analysis (ISD) at the Gottfried Wilhelm Leibniz Universität Hannover organize a workshop named "Impact of mechanical and thermal loads on the long term stability of PV modules" in the framework of the "MIKRO" project on 5 November 2013 at ISFH from 8:30 to 17:00.

We invite interested scientists to join the workshop and we are looking forward to a lively exchange of ideas and experiences. Participants should register and find more information at

The main focus of this workshop is on mechanical and electrical characterization as well as on simulation of PV modules. Both are imperative to understand power degradation of PV modules. That ranges from measuring single structural material properties to characterizing full scale PV modules. Invited speakers from research and equipment manufacturers give an overview of their current work.

The "Federal Ministry of Education and Research" is funding the joint project "Mikrorisse - Ursachen und Folgen für die Langzeitstabilität von PV-Modulen " between the ISFH and the ISD. This project investigates the origins and impacts of micro cracks on the long term stability of PV modules.

At peak periods, the installed PV modules already contribute up to 30 % to the generated electrical power in Germany. Increased module efficiencies as well as reduction of costs of the module fabrication have resulted in net parity in electricity production cost of crystalline silicon photovoltaics. New photovoltaic modules have warranties of at least 80 % of the initially declared power 20 years after installation. It is well known that thermal and mechanical loads can reduce the power of photovoltaic modules and the impact of such loads has already been investigated. However, in many cases the exact origins of the power degradation are still poorly understood. In order to reduce their impact and to increase the long term stability of the photovoltaic modules, it is important to identify the origins and mechanisms of the power degradation due to cell cracks.
