SQL database with detailed characteristic measurement results of photovoltaic modules that were subjected to accelerated aging sequences

<p>All measurement results are organized in an optimized database, which forms the information base for setting up models for climate sensitive ageing and degradation processes/mechanisms. The database is structured around the modules (module = device under test), see general scheme given in <a href="https://doi.org/10.1002/pip.3090">https://doi.org/10.1002/pip.3090</a>. Modules are logically connected via their specific ageing module groups with strictly associated ageing actions and instances. As stated above, a set of three identical modules is stored together in each specific ageing action (= accelerated ageing test as described in detail in Table&nbsp;<a title="Link to table" href="https://onlinelibrary.wiley.com/doi/10.1002/pip.3090#pip3090-tbl-0001">1</a> of <a href="https://doi.org/10.1002/pip.3090">https://doi.org/10.1002/pip.3090</a>) in order to increase the statistical reliability. Those triples are logically grouped in the database with the corresponding acquired measurement results being canonicalized and stored in the database as well. For future applications (modelling), all measurement information is kept as complete as possible; aggregation is avoided.</p> <a href="https://onlinelibrary.wiley.com/cms/asset/d5235350-b448-4094-b022-3b572d4c9317/pip3090-fig-0001-m.jpg" target="_blank" rel="noopener"></a>
