CdTe薄膜、纳米线、薄膜-纳米线组合和CdS-CdTe核-壳结构已经在光伏应用中产生结构的生长方法的初步调查中被制造出来。通过改变au催化CdTe在Mo或Si衬底上的VLS生长过程中存在的N2气体压力，可以实现薄膜、纳米线和薄膜加纳米线生长之间的选择性。研究了沉积在玻璃衬底上的溅射碲化镉薄膜上碲化镉纳米线的变质生长。在CdTe纳米线表面涂覆CBD CdS得到了适形覆盖，而涂覆MOCVD (Cd,Zn)S则在纳米线表面产生了高度结晶化的枝晶生长。
CdTe films, nanowires, film-nanowire combinations and CdS-CdTe core-shell structures have been fabricated in a preliminary survey of growth methods that will generate structures for PV applications. Selectivity between film, nanowire and film plus nanowire growth was achieved by varying the pressure of N2 gas present during Au-catalysed VLS growth of CdTe, on either Mo or Si substrates. Metamorphic growth of CdTe nanowires on sputtered CdTe films, deposited on glass substrates, was demonstrated. Coating of CdTe nanowires with CBD CdS gave conformal coverage whereas coating with MOCVD (Cd,Zn)S yielded highly crystallographic dendritic growth on the wires.
