摘要

我们研究了ITiO(氧化铟钛)的性能，作为更常用的TCO的替代品，如ITO(氧化铟锡)，ZnO:Al和SnO2:F。我们发现，在< 3×104 Ωcm的低片电阻率下可以达到50 cm2/Vs的迁移率。结果是，在1450 nm (0.85 eV)波长处，透射率超过75%，这是传统TCO在950 nm处透射率急剧下降的主要改进。

High mobility transparent conductive Oxide for low bandgap solar cells

We have investigated the properties of ITiO (Indium Titanium Oxide) as an alternative to the more commonly used TCO's, such as ITO (Indium Tin Oxide), ZnO:Al, and SnO2:F. We have found that a mobility of 50 cm2/Vs could be reached at a consistently low sheet resistivity of < 3×104 Ωcm. The result is that the transmission exceeds 75% up to a wavelength of 1450 nm (0.85 eV), which constitutes a major improvement over conventional TCO's that commonly show a sharp transmission drop at 950 nm.
