摘要

研究了ITO/CdS/CdTe/Au薄膜异质结太阳能电池制备工艺的影响。特别是，从光谱证据来看，ITO/CdS/CdTe层的空气退火可以产生异质结。XPS证据表明，这种加热在CdTe表面形成了CdO和TeO2，这些被KOH蚀刻去除。进一步的溴/甲醇蚀刻留下富Te的表面，与Au顶部电极形成注入接触，Te混合在其中。

Thin film CdS/CdTe solar cells

The effects of processes used in making thin film ITO/CdS/CdTe/Au heterojunction solar cells have been investigated. In particular, air annealing the ITO/CdS/CdTe layer is shown, from spectral evidence, to produce a heterojunction. XPS evidence shows that this heating forms CdO and TeO₂ on the CdTe surface and that these are removed by a KOH etch. A further bromine/methanol etch leaves a Te-rich surface which forms an injecting contact with the Au top electrode into which the Te mixes.
