Evaluation of encapsulant-free PV modules with Zebra back-contact solar cells

  • The back contact PV modules with encapsulant free Zebra cells offer a concept where high efficiency cells meet easy to recycle module components. Bifacial Zeb-ra cells of Reference module concept shows exceptional performance due to lack-ing front metallization resulting in a full surface joining the junction thanks to having all the metallization in the rear surface. New Industrial Solar CellThe back contact PV modules with encapsulant free Zebra cells offer a concept where high efficiency cells meet easy to recycle module components. Bifacial Zeb-ra cells of Reference module concept shows exceptional performance due to lack-ing front metallization resulting in a full surface joining the junction thanks to having all the metallization in the rear surface. New Industrial Solar Cell Encapsulation (NICE) module concept removes encapsulant layer and have top and bottom co-vers of the module out of glass providing recyclability as well as simplified manufac-turing process. For a comparison between both module types, it is important to outline differences, and this brings a workload to analyze nature of Cell to Module (CTM) losses in them. Also, simulation methods to validate experiments for 2 Zebra half-cell NICE and Reference modules are investigated and 120- half cells modules are simulated after the validation to have a grasp on power losses. As a part of optimization, structural changes considering series resistances are offered within the experi-ments and some further possible improvements are investigated through the simu-lations. In this manner, this thesis questions the potential of adding more copper to both unit NICE module and 120 half-cell modules and investigates the series re-sistances due to interconnection materials and offers improvement in the CTM power losses for both modules.show moreshow less
