| Popis: | 27th European Photovoltaic Solar Energy Conference and Exhibition; 430-432 The present research work aimed at developing an innovative photovoltaic module based on a glassfree lightweight and cost-effective encapsulation solution, easy and feasible to integrate in multifunctionality demanding applications such as BIPV and transport. The proposed solution is composed of an aluminium sheet as the backsheet and a transparent and monolithic glass fibre reinforced organic matrix composite as both, the encapsulant and frontsheet. The research work comprised encapsulation of commercial CIGS photovoltaic cells, being the composite manufactured through infusion process. Beyond the PV properties, the study was focused on the interface aluminium-composite, considered as a key factor for the performance of this approach. During the infusion process and curing of the composite the PV performance of the cells was not degraded, resulting in encapsulated cells with a 9.2%. After 200 thermal cycles (IEC 61646), a decrease in the electrical output of the cells was observed, but meeting the requirements of the standard. However, the pull-off adhesion strength was not affected by the cycles, remaining as high as 11MPa. These promising results will guide and motivate further studies of metal-composite encapsulation solutions devoted to integration purposes. |
