Based onb the preceding works for two years, we first selected cadmium telluride (CdTe) as a photo-voltaic material, because we could expect it to have the lattice adjustment with the oriented tin oxide (SnO_2) thin film as a substrate which we had successfully prepared. This compound was, however, judged not to become a hopeful material because of a included harmful element of cadmium. Secondiy we investigated the deposition of cuprous oxide (Cu_2O) thin film in consideration of safety and supply of raw material. We could determine the deposition conditions of Cu_2O thin film by the spray pyrolysis decomposition technique, but it was difficult to have the film oriented. It has proved that the further emphasis of the preferred orientation of SnO_2 thin film as a substrate should be required. From the same standpoints the deposition of tin sufide (SnS) thin film has also been attempted. Hence, a solar cell of SnO_2/SnS was fabricated and then the working of it was also confirmed.Furthermore? the enlargement of the surface area and the reduction of the resistivity of the oriented SnO_2 thin Film both was possible : from 50mm*50mm to 100mm*100mm in surface area ; from 2.8*10OMEGA cm to 5.2*10^<-4>OMEGA cm in resistivity. Consequently, we have been applying these promising results to novel solar cells composed of compound-semiconductive films, transparent conductive film, and so on.

基于前两年的工作，我们首先选择了碲化镉（CdTe）作为光伏材料，因为我们可以期望它能够与我们成功制备的取向氧化锡（SnO_2）薄膜作为衬底进行晶格调整。然而，由于含有有害元素镉，该化合物被认为不会成为一种有希望的材料。其次，考虑到安全性和原料供应，我们研究了氧化亚铜（Cu_2O）薄膜的沉积。利用喷雾热解技术可以确定Cu_2O薄膜的沉积条件，但薄膜的取向比较困难。事实证明，需要进一步强调SnO_2薄膜作为基底的择优取向。从相同的观点出发，还尝试了硫化锡（SnS）薄膜的沉积。由此，制备了SnO_2/SnS太阳能电池，并证实了其工作性能。此外？取向SnO_2薄膜的表面积增大，电阻率降低：表面积从50mm*50mm增大到100mm*100mm；电阻率从2.8*10Ωcm到5.2*10^-4Ωcm。因此，我们一直将这些有希望的结果应用于由化合物半导体薄膜、透明导电薄膜等组成的新型太阳能电池。
