中文摘要：

将纳米压印技术应用到三明治结构光伏器件制作．采用具有三维微结构（平行波纹、离散孤岛）软模具，通过纳米压印将定制化微三维结构转印到电子给体层和电子受体层的异质结界面上，以增大异质结界面实际面积，提高光伏效率．通过仿真计算，模拟了通过微结构界面几何改变，提高有效面积内异质结界面实际接触面积，从而增大载流子浓度的过程，优化三维微结构几何特征．典型试验结果证明了光伏器件异质结三维微结构界面对光伏效率的良好效果．

英文摘要：

The polydimethylsiloxane （PDMS） soft mould js approached to fabricate the organic hereo-structure of the photovoltaic （PV） device, which can be easily achieved by nano-imprint lithography （NIL） technology. Parallels and discrete diamonds, which critical dimension （CD） is in sub-micron range, are transferred through micro contacting between soft mould and polymer film. Theoretical deduction and simulation about electronic transition show that the fabrication of PV devices can improve its power conversion efficiency. Experimental results certificate the theoretical results.
