Low cost high energy yield solar module lines and its applications

Meyer Burger develops a high-efficiency line concept with a silicon heterojunction (HJT) cell based module. This line produces 2400 6-inch busbarless cells per hour and includes cells and modules characterization. The underlying high-efficiency bifacial module technology relies on the Smart Wire Connection Technology (SWCT) and on a Glass-Glass (GG) module design. The SWCT and GG concepts have been developed to benefit from the natural symmetry and bifaciality of the HJT cell. Our preliminary results demonstrate that our HJT cells can be incorporated into a record 60 156mm*156 mm cell module of 316 W. This paper reports on modules made on our pilot line in Switzerland and in Germany and presents outdoor measurement performances comparing our HJT bifacial modules with other technologies such as CdTe, CIGS and c-Si. Those results demonstrate a clear path towards modules with an equivalent power of 350 W for a 60-cell module.
