Abstract:
Lower sheet resistance for uniform emitter improved the conversion efficiency by 0.3%abs by doping profile manipulation. It also enables fewer front contact fingers with wider spacing due to the larger lateral conductivity in the emitter, which leads to the reduction of Ag paste consumption. 0.2%abs efficiency gain was achieved for 8% less front Ag paste and 0.1%abs efficiency gain for 11% less front Ag.
