铝掺杂对铜铟铝硒粉末微结构及光吸收影响的研究
Effect of Al incorporation on microstructure and optical absorption properties of CuIn1-xAlxSe2powders
摘要
Abstract
Cu(In1–xAlx)Se2(CIAS)was a popular solar cell material because of its lower cost than CIGS. CIAS powders with different Al contents were prepared by solvothermal method. The effects of Al incorporation on the microstructure and optical absorption of the CIAS compounds were characterized by XRD, SEM, XPS and ultraviolet-visibleabsorption spectra.The results indicate thatAl incorporationhas a significant effect on the microstructure ofCIASand appropriateAlincorporation is beneficial to the growth ofCIAScrystals.When themoleratio of Al is 0.4, the crystal (112) preferred growth is the most obvious, and the increase of the Al content can lead to the increase of the band gap, which is conducive to the optimized design of optoelectronic devices.关键词
