CuInSe₂ (CIS) nanowires were synthesized by solution-liquid-solid (SLS) growth in a high boiling solvent using bismuth nanocrystals as seeds. The nanowires tended to be slightly deficient in In and exhibited either cubic or hexagonal crystal structure, depending on the synthesis conditions. The hexagonal structure, which is not observed in bulk crystals, appears to evolve from large concentrations of twin defects. The nanowires could be compressed into a free-standing fabric or paper-like material. Photovoltaic devices (PVs) were fabricated using the nanowires as the light-absorbing layer to test their viability as a solar cell material and were found to exhibit measurable PV response.
铜铟硒（CIS）纳米线通过在高沸点溶剂中使用铋纳米晶作为晶种的溶液-液体-固（SLS）生长来合成。纳米线在铟方面略有不足，并表现出立方或六方晶体结构，这取决于合成条件。在块状晶体中观察不到的六方结构似乎是由大量孪晶缺陷演变而来的。纳米线可以被压缩成独立的织物或类似纸张的材料。使用纳米线作为光吸收层制造了光伏器件（PV），以测试它们作为太阳能电池材料的可行性，并发现它们具有可测量的光伏响应。
