17.0% Aperture Area Module Efficiency Using Large mc-Si Metal-Wrap-Through Cells
An integrated cell and module technology based on metal-wrap-through (MWT) cells has been developed and demonstrated. 243 cm2 large and 160 µm thin multicrystalline silicon MWT cells were made with a best cell efficiency of 17.9%. From 36 cells with an average efficiency of 17.8% a full-size module was made with an efficiency of 17.0% (aperture area). The module was made using a conductive rear-side foil with conductive adhesive for the interconnection. The module was constructed using a dedicated module manufacturing line that is designed to be able to work with extremely thin cells and provide a high through-put of one 60 cell module per minute.
