本文对渗杂梯度化的 nip 型α—Si 太阳电池的短路电流 J_(sc)和效率η作了计算。结果如下:1.0.5μ和1.0μ厚电池的本征 J_(sc)分别达23.3mα/cm~2和25.3mα/cm~2.它们很接近于Carlson 的计算结果.在表面反射和电极复盖光损失各占10%条件下算得0.5μ和1.0μ电池的效率分别为12.69%和14.4%。2.与0.5μ厚均匀渗杂的 nip 型 a—Si 实验电池比较,发现 V_(oc)很接近,但 J_(sc)、FF 和η比梯度化电池低得多,这显然是由于均匀渗杂实验电池中存在较大的复合损失和串联电阻引起的。如果用在消除复合损失条件下所得到的最佳填充因子0.7计算,0.5μ厚梯度化电池可以达到大于10%效率.
In this paper, the short-circuit current J sc and efficiency η of the graded nip-type α-Si solar cell are calculated. The results are as follows: The intrinsic J sc for 1.0.5 μ and 1.0 μ thick cells reached 23.3 mα / cm 2 and 25.3 mα / cm 2, respectively, which are very close to Carlson's calculations. In the case of surface reflection and electrode coverage The efficiencies of 0.5μ and 1.0μ cells calculated for light loss of 10% were 12.69% and 14.4%, respectively. Compared with the nip-type a-Si experimental cells with a uniform thickness of 0.5μ, V oc was found to be very close, but J sc, FF and η were much lower than those of graded cells, apparently due to the uniform Miscellaneous experimental battery there is a large composite loss and series resistance caused. A 0.5μ thick graded cell can achieve greater than 10% efficiency if calculated using the optimal fill factor of 0.7 obtained to eliminate recombination losses.
