Development of Large-Area Bifacial Interdigitated-Back-Contact (IBC) Solar cell with Industrial Production Environment
conference paper
IBC Solar cell process was developed based on the same process equipment as used for the Yingli N-type Panda Si solar cell technology. Recombination at surface and metal contact areas as well as contact resistivity were investigated and optimized to get a balance between Voc and FF. Moreover, the IR characteristics at -10V shown homogeneous temperature distribution upon reverse polarization, which indication of hotspot prevention by the structure of IBC cell design. The latest cell efficiency of 21.6% reached on 242.85 cm2 Si wafer demonstrates that production and commercialization of IBC solar cell based on Yingli N-type Panda solar cell production line is possible. Furthermore, the simple rear metallization design of IBC cell allows for a bifacial application and the cell efficiency of the champion cell on rear side is 15.92%. © 2018 IEEE.
