Abstract:
We obtained 17.6% cell efficiency on 160 µm and 17.1% on 120 µm thin multicrystalline silicon screen printed cells of 156 x 156 mm2. These cells are the best from two batches of cells that have been produced using improved processing on ECN’s industrial metal-wrap-through (MWT) cell concept. With these batches of cells, four 36-cells modules were made: two modules with 160 ?m thin cells and two modules with 120 ?m thin cells. The module manufacturing, which is based on a conducting substrate foil, succeeded with 100% yield in our module pilot line. The modules were independently measured by TÜV Rheinland and JRC-ESTI, and resulted in a new certified world record module efficiency of 16.4% on an aperture area of 8904 cm2.
