利用非晶硅发射极和背接触层在p型晶片上制作了高效的晶硅异质结太阳电池。独立确认的AM1.5转换效率在浮动区晶片上为19.3%，在直拉晶片上为18.8%；转换效率没有显示出明显的光诱导退化。最佳开路电压为700 mV以上。表面清洁和钝化对异质结太阳电池的性能起着重要的作用。
Efficient crystalline silicon heterojunction solar cells are fabricated on p-type wafers using amorphous silicon emitter and back contact layers. The independently confirmed AM1.5 conversion efficiencies are 19.3% on a float-zone wafer and 18.8% on a Czochralski wafer; conversion efficiencies show no significant light-induced degradation. The best open-circuit voltage is above 700 mV. Surface cleaning and passivation play important roles in heterojunction solar cell performance.
