| 摘 要： | 通过单晶硅表面制绒可以降低太阳能电池面板对光的反射率进而提高电池的转化效率。利用Na2CO3、NaHCO3和Na2CO3/NaHCO3溶液进行了单晶硅表面制绒,并利用扫描电子显微镜和紫外/可见光光度计对所得绒面的形貌及反色率分别进行了分析。研究了溶液浓度、溶液组成及反应时间等因素对所制单晶硅绒面反射率的影响。结果表明:在Na2CO3:NaHCO3质量比为10:1,反应温度为85℃,反应时间为10 min时,可获得反射率为15.22%的绒面。 |

| Abstract: | The conversion efficiency of solar cell could be improved by reducing the reflectivity of solar panel by texturing the panel surface.In this study,the surfaces of monocrystalline silicon chips,a common type of solar panel,were texturized with Na2CO3,NaHCO3 and Na2CO3/NaHCO3 solution.The morphology and reflectivity of the texturized surfaces were characterized with scanning electron microscope(SEM) and UV-Vis spectrophotometer,respectively,and the effects of solution concentration,solution composition and reaction time on the reflectivity of the texturized surfaces were studied.The results show that a texturized surface with a reflectivity of 15.22% can be prepared by immersing the silicon chip in the Na2CO3/NaHCO3solution containing 12wt% Na2CO3and 1.2wt% for 10 minutes at 85 ℃. |
