本文研究了一种受蝴蝶翅膀鳞片启发的新型光阳极结构，并将其应用于染料敏化太阳能电池。以蝴蝶翅膀为生物模板，在氟掺杂氧化锡涂层玻璃基底上分别合成了准蜂窝状结构（QHS）、浅凹结构（SCS）和交叉肋结构（CRS）。的光阳极，这是保持从原来的蝴蝶翅膀的形态，其特征在于通过扫描和透射电子显微镜。结果表明，煅烧后的光阳极具有蝴蝶翅膀结构，由纳米颗粒组成的排列的脊和肋，完全结晶。对可见光吸收光谱的分析表明，由于QHS光阳极的特殊微结构，其捕光效率高于不含生物模板的普通二氧化钛光阳极，从而提高了太阳能电池的整体效率。
We studied a novel photoanode structure inspired by butterfly wing scales with potential application on dye-sensitized solar cell in this paper. Quasi-honeycomb like structure (QHS), shallow concavities structure (SCS), and cross-ribbing structure (CRS) were synthesized onto a fluorine-doped tin-oxide-coated glass substrate using butterfly wings as biotemplates separately. Morphologies of the photoanodes, which were maintained from the original butterfly wings, were characterized by scanning and transmission electron microscopies. The results show that the calcined photoanodes with butterfly wings’ structures, which comprised arranged ridges and ribs consisting of nanoparticles, were fully crystallined. Analysis of absorption spectra measurements under visible light wavelength indicates that the light-harvesting efficiencies of the QHS photoanode were higher than the normal titania photoanode without biotemplates because of the special microstructures, and then the whole solar cell efficiency can be lifte...
