II型同轴纳米线由于其独特的光学和电学特性，在光伏器件领域获得广泛关注。其中，ZnO纳米线由于其成本低、稳定性好、工艺成熟等优点，更是被广泛运用于太阳能电池研究。然而，由于它的带隙较宽，不能有效吸收太阳光，直接用它制备的电池效率较低。为了增加光吸收，人们主要利用带隙较窄的ZnSe、CdSe、ZnCdSe等材料敏化ZnO纳米线，以期制备出更高效的太阳能能电池。本文采用计算机仿真模拟方法，利用FDTDSolutions和ModeSolutions软件研究了ZnO基II型同轴纳米线阵列的光学性质。通过对ZnO/ZnSe单壳层及ZnO/ZnSe/CdSe双壳层纳米线阵列结构的优化设计，提高了材料对光的...Type-II coaxial nanowires with their unique optical and electrical properties, have aroused world wide interest in the field of photovoltaic devices. Especially, because of the low cost, good stability, process maturity, etc., ZnO nanowires are widely used in solar cells. Unfortunately, due to the wide band gap, ZnO cannot effectively absorb the sunlight, leading to a low efficiency of the solar c...学位：工程硕士院系专业：物理与机电工程学院_工程硕士(电子与通信工程)学号：X201018102
