摘要

采用溶胶-凝胶法在FTO/glass衬底上制备了(BiFeO_3)_(1-x)-(BaTiO_3)_x固溶薄膜。(BiFeO_3)_(1-x)-(BaTiO_3)_x固溶薄膜的退火温度为500℃,组分比例为x=0,0.05,0.10,0.20。x=0,0.05,0.10,0.20的(BiFeO_3)_(1-x)-(BaTiO3)x固溶薄膜的带隙分别为2.57 eV,2.44 eV,2.59 eV,2.74 eV。通过BaTiO_3的固溶,BiFeO3的光伏效应得到了显著增强。通过20%BaTiO3的固溶,BiFeO_3的短路电流密度由4.47 nA/cm~2增加到1.56μA/cm~2。(BiFeO_3)_(0.80)-(BaTiO_3)_(0.20)薄膜的V_(oc)通过极化也得到了极大的提高。
(BiFeOs)_(1-x)-(BaTiO_3)_x solid solution thin films were grown on FTO/glass substrates by a sol-gel method.The(BiFeO_3)_(1-x)-(BaTiO_3)_x films with x=0,0.05,0.10,0.20 were prepared by annealing at 550 ℃.X-ray diffraction patterns indicate that the(BiFeO_3)_(1-x)-(BaTiO_3)_x solid solution thin films adopt random orientation.Improved photovoltaic property at room temperature was observed in the BaTiO_3 incorporated BiFeOs films.The band gaps of the(BiFeO_3)_(1-x)-(BaTiO_3)_x film with x=0,0.05,0.10,0.20 are 2.57 eV,2.44 eV,2.59 eV and 2.74 eV,respectively.The BaTiOs incorporated BiFeOs films show substantially enhanced photovoltaic property.By solid solution of 20%BaTiO_3.the J_(oc) increased to 1.56 μA/cm~2 from 4.47 nA/cm~2 of the BiFeO_3 film.The V_(oc) of the(BiFeO_3)_(0.80)-(BaTiO_3)_(0.20) film can be substantially enhanced by polarization.
