Suspensions of single-walled, double-walled and multi-walled carbon nanotubes (CNTs) were generated in the same solvent at similar concentrations. Films were fabricated from these suspensions and used in carbon nanotube/silicon heterojunction solar cells and their properties were compared with reference to the number of walls in the nanotube samples. It was found that single-walled nanotubes generally produced more favorable results; however, the double and multi-walled nanotube films used in this study yielded cells with higher open circuit voltages. It was also determined that post fabrication treatments applied to the nanotube films have a lesser effect on multi-walled nanotubes than on the other two types.

在相同溶剂中以相似浓度制备了单壁、双壁和多壁碳纳米管（CNT）悬浮液。由这些悬浮液制备薄膜，并将其用于碳纳米管/硅异质结太阳能电池，然后根据纳米管样品中的壁数对其性能进行比较。结果发现，单壁纳米管通常产生更有利的结果；然而，本研究中使用的双壁和多壁纳米管薄膜制成的电池具有更高的开路电压。还确定，对纳米管薄膜进行的后处理对多壁纳米管的影响比对其他两种类型的纳米管的影响小。
