- 摘要：In this paper, we report passivation properties of inverted pyramidal nanostructure based multi-crystalline silicon (mc-Si) by Al2O3 films with spin-coating method. Precursors AlCl3 and Al(acac)(3) for Al2O3 films were chosen for comparison. Al2O3/SiOx stacks were found to be able to passivate the nanostructured surface well. With the number of spin-coating up to five, the Al2O3 films could conformally attach the nanostructure. The weighted average reflectance values (ranging from 400-900 nm) of the passivated silicon surface could be reduced to 10.74% (AlCl3) and 11.12% (Al(acac)(3)), and the effective carrier lifetime could reach 7.84 and 16.98 mu s, respectively. This work presented a potential process to fabricate low cost high efficiency mc-Si solar cells.
