通过膜层设计软件(TFCalcTM )设计了在400~1100 nm波长范围内具有高透过率的单层增透膜.以正硅酸乙酯(TEOS)和甲基三乙氧基硅烷(MTES)为共混前驱体、盐酸为催化剂、十六烷基三甲基溴化铵(CTAB)为模板剂制得甲基修饰的二氧化硅溶胶，通过浸渍提拉法结合溶剂挥发自组装技术成功制备了所设计的多功能单层增透膜.结果表明，(1)增透膜在650 nm的最大透过率可达到99．9％，在400~1100 nm 波长范围内的光伏透过率(TPV )高达98．7％，与软件设计结果一致；(2)TEOS 与 MTES 共聚后，显著提高增透膜的疏水性，其对水的接触角从24°提高至85°；(3)单层二氧化硅增透膜具有较好的耐磨擦性.这种兼具高透过率、耐磨擦性和一定疏水性的多功能增透膜在太阳能电池领域具有应用价值.

Single-layer antireflective (AR)coatings with high transmittance have been designed by the thin film design software (TFCalcTM).The silica sols were prepared by using tetraethylorthosilicate (TEOS)and methyl-triethoxysilane (MTES)as co-precursors,HCl as catalyst,and cetyltrimethylammonium bromide (CTAB)as template.The single-layer AR coatings with multi-functions were prepared by the dip-coating process combined with evaporation-induced self-assembly.It was found that the transmittance of AR coatings at 650 nm was 99. 9%,and the photovoltaic transmittance (TPV)at 400-1 100 nm reached to 98.7%.The introduction of methyl groups increased the water contact angle of AR coatings from 24°to 85°.In addition,this AR coating also had good abrasion-resistance.This multi-functional silica AR coating with high transmittance,good abrasion-resist-ance and improved hydrophobicity will find important application in the field of solar cells.
