ZnO nanocrystals with a particle size of 20-30 nm have been synthesised for the first time using a template-free method. Chalcopyrite Cu0.28In1.72Se2.72 nanocrystals (5-10 nm) were directly anchored on ZnO nanocrystals by a vacuum one-pot-nanocasting process without any long ligands. We further investigated Cu0.28In1.72Se2.72 quantum dots and dye bilayer-sensitized solar cells, which exhibited power conversion efficiency of 57.4% higher than the single-dye-sensitized solar cells.
首次采用无模板法合成了粒径为20 - 30 nm的氧化锌纳米晶体。通过真空一锅纳米铸造工艺，在没有任何长配体的情况下，将黄铜矿型Cu0.28In1.72Se2.72纳米晶体（5 - 10 nm）直接锚定在氧化锌纳米晶体上。我们进一步研究了Cu0.28In1.72Se2.72量子点和染料双层敏化太阳能电池，其功率转换效率比单染料敏化太阳能电池高57.4%。
