A modification to the conventional anti-reflection coating (ARC) is proposed to improve the performance of the amorphous silicon solar cells. The performance is improved by replacing the conventional anti-reflection coating (ARC) by a modified ARC. The modified ARC has an embedded array of silver Yagi–Uda nanoantenna. Due to the highly directive and broadband characteristics of Yagi–Uda nanoantenna, the modified ARC minimizes the reflection over large range wavelengths and guides the incoming solar radiation towards absorber layer effectively which results in increased absorption and subsequent increase in the short-circuit current density. Solar cell with proposed ARC exhibits 1.66 times improved short-circuit current density and 1.43 times increased conversion efficiency. To the best of our knowledge, this is the first report on a Yagi–Uda nanoantenna incorporated in a solar cell to improve its performance.

使用嵌入抗反射涂层内的八木-宇田纳米天线阵列增强薄膜太阳能电池的性能

建议对传统的抗反射涂层 (ARC) 进行修改,以提高非晶硅太阳能电池的性能。通过用改进的 ARC 代替传统的抗反射涂层 (ARC) 来提高性能。改进后的 ARC 具有嵌入的银 Yagi-Uda 纳米天线阵列。由于 Yagi-Uda 纳米天线的高指向性和宽带特性,改进的 ARC 最大限度地减少了大范围波长的反射,并将入射的太阳辐射有效地引导到吸收层,导致吸收增加,随后短路电流密度增加。提出的 ARC 太阳能电池的短路电流密度提高了 1.66 倍,转换效率提高了 1.43 倍。据我们所知,
