摘要
多晶硅(mcSi)太阳能电池的效率主要受材料的少数载流子寿命的影响。mcSi的寿命在处理过程中变化很大。逐步监测可以识别有益和不良的处理步骤,并导致细胞效率的快速提高。磷的吸附显著提高了所研究的mcSi衬底的寿命,在1.5 /spl ω / cm mcSi中观察到250 /spl mu/s的有效寿命。这使得0.2 /spl Omega/ cm和0.5 /spl Omega/ cm mcSi太阳能电池的开路电压大于655 mV,效率大于18%。
Processing dependence of minority carrier lifetimes in multicrystalline silicon
Multicrystalline silicon (mcSi) solar cell efficiency is primarily influenced by minority carrier lifetime of the material. Lifetimes in mcSi vary strongly during processing. Step by step monitoring has allowed identification of both beneficial and poor processing steps and lead to rapid improvements in cell efficiency. Phosphorous gettering significantly improves lifetimes in the mcSi substrates investigated, where effective lifetimes of 250 /spl mu/s in 1.5 /spl Omega/ cm mcSi have been observed. This has permitted the achievement of record open circuit voltages greater than 655 mV and efficiencies greater than 18% with 0.2 /spl Omega/ cm and 0.5 /spl Omega/ cm mcSi solar cells.
