    摘要:

    通過低溫水熱法，在圖案化的p型硅襯底上合成氧化鋅（ZnO）納米棒陣列薄膜，制備出具有p-Si/n-ZnO納米棒（NR）陣列結(jié)構(gòu)的異質(zhì)結(jié)太陽能電池（HSCs）。通過直流磁控濺射技術(shù)，分別在前后面板濺射沉積ITO和Al膜接觸電極層。研究ZnO籽晶層的退火溫度、ZnO納米棒陣列水熱合成的時間等因素對ZnO納米棒陣列的晶體結(jié)構(gòu)、表面形貌和光學(xué)性能的影響。p-Si/n-ZnO納米棒陣列HSCs的最佳短路電流密度和總能量轉(zhuǎn)換效率分別為11.475 mA·cm-2和2.0%。相比p-Si/n-ZnO薄膜HSCs，p-Si/n-ZnO納米棒陣列HSCs的光伏性能得到了有效提高。

    Abstract:

    Heterojunction solar cells (HSCs) with the structure of p-Si/n-ZnO nanorod (NR) arrays were prepared by synthesizing a ZnO NR array film on patterned p-type silicon substrate through a low temperature hydrothermal method. ITO and Al films as the front and back contact electrode layers were deposited by DC-magnetron sputtering, respectively. The influences of various factors, such as annealing temperature for seed layer and hydrothermal synthesis time for ZnO NR arrays, on the crystal structure, surface morphology, and optical property of the ZnO NR array film were investigated. Results show that the optimized short-circuit current density and allover energy conversion efficiency of the p-Si/n-ZnO nanorod array HSCs are 11.475 mA·cm-2 and 2.0%, respectively. Compared with those of p-Si/n-thin film ZnO solar cell, the photovoltaic properties of the p-Si/n-ZnO nanorod array HSCs are improved significantly.
