Optimized gettering can improve heterojunction solar cell efficiency by 0.21%

Researchers in China have investigated the impact of phosphorus diffusion gettering on industrial silicon heterojunction solar cell and have found that, with an optimized gas flow, higher efficiencies can be achieved. A Chinese research team led by the Shanghai Jiao Tong University has evaluated the impact of gettering in the manufacturing of heterojunction (HJT) solar cell technologies and has concluded it can help improve device efficiency. "We investigated, in particular, the impact of the phosphorus diffusion gettering (PDG) process on n-type HJT solar cells," the research's corresponding ...
