摘 要: 应用直流反应磁控溅射设备在硅基底上制备TiO2薄膜,利用n&k仪对薄膜的反射率进行检测,结果表明TiO2薄膜可以作为太阳电池减反射薄膜应用,并且通过改变工艺条件可以调控薄膜的反射低谷。当总压强为2×10-1Pa、O2流量为15 sccm、靶基距为190 mm、温度为60℃的条件下制备的TiO2薄膜的减反射效果最好。 The reflectance of the TiO2 films, grown by D C reactive magnetron sputtering on silicon substrates, was studied. The results show that TiO2 films can be good anti-reflectance materials in solar cells and that judicious choice of the film growth conditions may improve its anti-reflectance. The optimized growth conditions are as follows:total gas pressure 2 ×10^-1 Pa,oxygen flow rate, 15 sccm,substrate temperature,60℃ and substrate-target separation, 190 mm.
