以均苯四甲酸酐、尿素和氯化铜等为原料,结合冷冻干燥技术,制备溶解性较强的染料敏化剂八羧基酞菁铜(CuOCPc),并采用浸渍提拉法在ITO玻璃上制备CuOCPc薄膜。通过傅里叶红外光谱和原子力显微镜对其基团和成膜性能进行表征,并利用紫外分光光度计和光电综合测定仪研究其光电性能。结果表明,经真空冷冻干燥后的多孔的CuOCPc溶解性能得到明显提升,多次提拉后制得的薄膜表面粗糙度为26.4,CuOCPc薄膜在整个可见光谱内吸收较强,其能带隙为1.60eV,是一种性能良好的光伏材料。
With pyromellitic dianhydride, urea and copper chloride as raw materials, combined with freeze-drying technology, preparation of highly soluble dye sensitizer copper octacarboxyphthalocyanine (CuOCPc), and by dip-lift method in the ITO glass Preparation of CuOCPc film. Its groups and film-forming properties were characterized by Fourier transform infrared spectroscopy and atomic force microscopy, and their optoelectronic properties were studied by UV spectrophotometer and optoelectronic comprehensive analyzer. The results showed that the solubility of porous CuOCPc after vacuum freeze-drying was significantly improved. The surface roughness of the CuOCPc film was 26.4 after several times of pulling. The CuOCPc film absorbed strongly in the whole visible spectrum with a band gap of 1.60 eV, is a good performance of photovoltaic materials.
