采用喷雾热解技术，在钠钙玻璃衬底上成功制备了Cu2ZnSnS4(CZTS)薄膜，该薄膜是一种潜在的薄膜异质结太阳电池吸收层候选材料。研究了衬底温度对CZTS薄膜生长的影响。X射线衍射研究表明，在643-683K的衬底温度范围内，可以得到结晶度较好的多晶CZTS薄膜，其晶胞参数为a=0.542，c=1.085 nm。在不同衬底温度下沉积的薄膜的光学带隙在1.40-1.45 eV之间。测得其平均光吸收系数为10(4)cm(-1)。(C)2009爱思唯尔B.V.保留所有权利。
Thin films of Cu2ZnSnS4 (CZTS),a potential candidate for absorber layer in thin film heterojunction solar cell, have been successfully deposited by spray pyrolysis technique on soda-lime glass substrates. The effect of substrate temperature on the growth of CZTS films is investigated. X-ray diffraction studies reveal that polycrystalline CZTS films with better crystallinity could be obtained for substrate temperatures in the range 643-683 K. The lattice parameters are found to be a = 0.542 and c = 1.085 nm. The optical band gap of films deposited at various substrate temperatures is found to lie between 1.40 and 1.45 eV. The average optical absorption coefficient is found to be > 10(4) cm(-1). (C) 2009 Elsevier B.V. All rights reserved.
