A preparation method of copper-indium-tellurium thin film material prepared by nitrate system belongs to the technical field of photoelectric thin film preparation. The invention is obtained by the following steps: firstly, the glass substrate is cleaned, then TeO2, Cu (NO3) 2 and In (NO3) 3 are put into the solvent to prepare a clear and transparent solution, and the precursor thin is obtained on the glass sheet by spin coating method. The film is dried naturally and placed in a sealed container with hydrazine so that the precursor film sample does not contact with hydrazine. The sealed container containing the precursor film sample is heated and then the sample is taken out for drying. The film quality can be improved by increasing the reaction times and heat treatment process. The invention does not need high temperature and high vacuum conditions, requires low instrument and equipment, has low production cost, high production efficiency and is easy to operate. The obtained Cu-in-tellurium photoelectric thin films have good continuity and uniformity. This new process provides a low cost and industrialized production method for preparing high performance Cu-in-tellurium photoelectric thin films.

,尤其涉及一种硝酸盐体系制备铜铟碲薄膜的方法。
技术介绍
铜铟碲基薄膜太阳电池目前可以认为是最有发展前景的薄膜电池,这是因为其吸收层材料CuInTe2具有较高的光电转化率等一系列优点。特别是以铜铟碲光电薄膜的制备研究已经取得了较大的进展。目前铜铟碲薄膜的制备方法主要有溶剂热法、喷射热解法、离子烧结法、化学沉积法、反应溅射法、真空蒸发法等。由于原料成本低,因此是一种非常有发展前途的光电薄膜材料,但现有工艺路线复杂、制备成本高,因而需要探索低成本的制备工艺。如前面所述方法一样,其它方法也有不同的缺陷。与本专利技术相关的还有如下文献:[1]I.T.Zedana,E.M.El-Menyawy,Illumination-inducedchangesontheopticalfunctionsandvalencebandsplittingparametersofflashevaporatedCuInTe2films.Optik-InternationalJournalforLightandElec ...
