【摘要】：提高太阳电池的光电转化效率是光伏研究中最重要的问题，然而，，有10%以上的光能在太阳能电池的封装玻璃表面由于反射而损失掉。在玻璃表面制备减反射膜可以起到增透作用，针对不同种类太阳电池的不同响应波段制备减反射膜可以使电池的转换效率得到有效的提高。 本文探索性地采用成本低、设备简单、生产周期短的超声喷雾热解法和优化的超声雾化模式制备出适用于不同太阳电池的SiO_2/TiO_2减反射薄膜。 研究了喷射距离、载气流量、前驱液的选择和流量、衬底温度、热处理时间等工艺条件对薄膜结构和光学性能的影响，找到最优化的工艺条件并确定薄膜材料的光学参数。发现500℃时制备出的TiO_2薄膜呈锐钛矿，SiO_2薄膜呈非晶结构，保温热处理10min后的折射率分别为2.23和1.42。 根据所得单层薄膜的光学参数结果，结合光学薄膜理论，利用软件优化设计出适用于非晶硅太阳电池的双层减反射膜系和适用于微晶、非/微叠层及晶硅太阳电池的六层减反射膜系，理论平均剩余反射率为1.193%和0.879%。 根据膜系的优化结果，采用载玻片为衬底，制备出两种应用于太阳能电池的减反射膜，使玻璃的透过率分别提高了10.8%和10.4%。通过附着性测试和机械性能测试表明减反射膜具有较强的物理性能。
[Abstract]:Improving the photovoltaic conversion efficiency of solar cells is the most important problem in photovoltaic research. However, more than 10% of the light energy is lost in the solar cell packaging glass surface due to reflection. Antireflection film on glass surface can play an antireflection effect, and the conversion efficiency of solar cell can be improved effectively by preparing antireflection film in different response bands of different kinds of solar cells. In this paper, SiO_2/TiO_2 antireflective thin films suitable for different solar cells are prepared by ultrasonic spray pyrolysis with low cost, simple equipment and short production cycle and optimized ultrasonic atomization mode. The effects of injection distance, carrier gas flow rate, the selection and flow rate of precursor liquid, substrate temperature and heat treatment time on the structure and optical properties of the film were studied. The optimum process conditions were found and the optical parameters of the film materials were determined. It was found that the TiO_2 thin films prepared at 500 鈩
