Improvement of photovoltaic modules - measures for withstanding electrical and thermal effects caused by reverse biasing of cells (IMOTHEE)

Objective

Long lifetimes (>20) of photovoltaic modules (PVM) are a precondition for cost effective operation of PV systems. Besides environmental factors hot-spot heating affects the lifetimes of PVM. European module manufactures are uncertain about the operational behaviour of commercial cells under reverse biased conditions and hence about suitable hot-spot safety measures for the modules. For thin-film PVM this problem in not adequately investigated. Therefore the project will contribute to improving the module design for the different cell technologies that have achieved production level. Each consortium partner contributes a complementary level of expertise to this project (cell and module characterisation, cell processing and module manufacturer). Long lifetimes of PVM will positively affect the efficiency of PV systems and thus create greater acceptance among the public and increased demand and economic growth in Europe.
