在这项研究中，我们研究了使用聚苯乙烯-聚二甲基硅氧烷（PS-PDMS）在硅衬底上自组装大面积纳米点制造，以应用于量子点太阳能电池。通过优化PS-PDMS浓度为2%和PS-PDMS溶液的体积为20 μL/cm 2滴到硅衬底上，获得了间距尺寸为33 nm，直径为23 nm，分子量为30，000 - 7，500的纳米点。研究发现，PS-PDMS溶液的滴加量与PS-PDMS旋涂层的厚度相关，对图形的尺寸和形貌有很大的影响。
In this study, we investigate self-assembled large-area nanodot fabrication on a silicon substrate using poly(styrene)-poly(dimethyl-siloxane) (PS-PDMS) for the application to quantum dot solar cell. By optimizing the PS-PDMS concentration by 2% and the volume of PS-PDMS solutions by 20 μL/cm2 dropped to silicon substrate, nanodots with a pitch size of 33 nm and a diameter of 23 nm are achieved with the molecular weight of 30,000-7,500. It is found that the dropped volume of PS-PDMS solution correlated to the thickness of spin-coated PS-PDMS layer has a great effect on the size and the pattern morphology.
