英文摘要	将原料封装入真空石英管,在873 K进行固相反应制各了Li掺杂的Cu1-xLixInSe2(x=0-0.4)块体材料,并对该材料的结构、电学和光学特性进行了系统性的研究.Li掺杂之后,样品的晶体结构还保持黄铜矿结构,并能得到更大的晶粒.而电阻率从1.98×102 Ω·cm增大到2.73×108 Ω·cm.光学能隙也从0.90 eV提高到1.33 eV,增大了光伏开路电压.实验结果表明,Li掺杂的Cu1-xLixInSe2能有效提高光电材料的性能.; Bulk materials of Li-doped Cu1-xLixInSe2 (x = 0-0.4) were prepared by solid state reaction in evacuated and sealed quartz tubes at 873 K. To understand the physical properties of the materials, the structural, electrical and optical properties were systematically investigated. After doping with lithium, the samples crystallize in chalcopyrite structure with large grain sizes. Electrical resistivity and optical band gap of Li-doped Cu1-xLixInSe2 are greatly enhanced to 2.73x10(8) Omega.cm and 1.33 eV from original values of 1.98x10(2) Omega.cm and 0.9 eV, respectively. The large band gap improves the open circuit voltage, indicating that the Li-doping CuInSe2 could be a promising material to future photovoltaic applications.; National Natural Science Foundation of China; Science and Technology Commission of Shanghai; Key Research Program of Chinese Academy of Sciences; SCI(E); 1; 101-106; 32
