In this research, chalcopyrite Cu(In,Ga)(S,Se)_2 thin films were prepared by the new process applicable to the large scale production, which was the sequential evaporation from ternary compounds. Moreover, their solar cells were manufactured by way of trial and their properties were investigated.(1)The new process to prepare Cu(In,Ga)Se_2 thin films was examined. In the first step, Cu-In-Ga-Se layer was evaporated from CuInSe_2 and CuGaSe_2 ternary compounds onto the Mo/soda-lime glass substrate. In the second step, In-Se layer was deposited from In_2Se_3 compound at a substrate temperature of 490℃. Finally, only Se was effused at the same substrate temperature. The surface composition of Cu(In,Ga)Se_2 thin film could be controlled in the optimum range by adjusting the amount of In_2Se_3.(2)Cu(In,Ga)(S,Se)_2 thin films were prepared by simultaneously evaporating In_2Se_3 and In_2S_3 compounds in the second step of the above process. The S content in Cu(In,Ga)(S,Se)_2 thin films was inc … More reased with increasing the amount of In_2S_3 in the second step.(3)Cu(In,Ga)(S,Se)_2 thin films were prepared by thermal crystallization from CuInGaSe/CuGaSe stacked precursor in S and Se atmosphere. The precursors were prepared by evaporating consecutively from the CuGaSe_2 and Cu(In,Ga)Se_2 compounds. The grain sizes in Cu(In,Ga)(S,Se)_2 thin films were increased with increasing the crystallization temperature.(4)The best solar cell using Cu(In,Ga)Se_2 thin film prepared by the new process demonstrated Voc=330mV, Isc=28.3mA/cm^2, FF=0.461 and Eff=4.31% without AR-coating. The open circuit voltage in Cu(In,Ga)(S,Se)_2 thin film solar cell was improved by using In_2S_3 compound as a S source.As a result, the method to produce Cu(In,Ga)(S,Se)_2 thin films from ternary compounds was clarified for application to fabricate an advanced thin film solar cell with low cost and high efficiency. Moreover, the trial production of their solar cells suggested the future direction of research for improvement in solar cell performance. Less

本研究采用适用于大规模生产的新工艺，即三元化合物的顺序蒸发法制备了Cu(In,Ga)(S,Se)_2黄铜矿薄膜。此外，还通过试验制作了它们的太阳能电池，并对其性能进行了研究。(1)研究了制备Cu(In,Ga)Se_2薄膜的新工艺。第一步，将CuInSe_2和CuGaSe_2三元化合物中的Cu-In-Ga-Se层蒸发到Mo/钠石灰玻璃衬底上。第二步，在490℃的衬底温度下，由In_2Se_3化合物沉积In- se层。最后，在相同的衬底温度下，只有Se析出。通过调节In_2Se_3的用量，可以将Cu(In,Ga)Se_2薄膜的表面组成控制在最佳范围内。(2)第二步将In_2Se_3和In_2S_3化合物同时蒸发制备Cu(In,Ga)(S,Se)_2薄膜。Cu(in,Ga)(S,Se)_2薄膜中的S含量随着第二步In_2S_3用量的增加而增加。(3)以CuInGaSe/CuGaSe为前驱体，在S - Se气氛下热结晶制备Cu(In,Ga)(S,Se)_2薄膜。由CuGaSe_2和Cu(In,Ga)Se_2化合物连续蒸发制备前驱体。Cu(in,Ga)(S,Se)_2薄膜的晶粒尺寸随着结晶温度的升高而增大。(4)采用新工艺制备的Cu(In,Ga)Se_2薄膜制备的最佳太阳能电池，无ar涂层时，Voc=330mV, Isc=28.3mA/cm^2， FF=0.461, Eff=4.31%。采用In_2S_3化合物作为S源，提高了Cu(in,Ga)(S,Se)_2薄膜太阳能电池的开路电压。研究结果阐明了用三元化合物制备Cu(In,Ga)(S,Se)_2薄膜的方法，为低成本、高效率地制备先进的薄膜太阳能电池奠定了基础。此外，他们的太阳能电池的试制表明了未来的研究方向，以提高太阳能电池的性能。少
