非对称聚光跟踪光伏系统——光伏组件功率倍增器的研究及应用

"聚光光伏"是完全可进一步降低光伏电力成本的技术路线,但必须解决3个问题:应以质好价廉的光伏组件为聚光对象;充分利用价廉物美的聚光镜进行均匀聚光;发明一种可靠、廉价且免维护的二维精确对日跟踪系统。研制了一种非对称聚光跟踪光伏系统解决了以上问题,称为"光伏组件功率倍增器";本文详细介绍该系统具备的核心技术,从总增益和产业化成本分析可知,随着光伏组件效率的提高,该系统的降本优势会越来越大。

Multiple Plasmonic Resonances and Cascade Effect in Asymmetrical Ag Nanowire Homotrimer

Plasmonic Ag nanowire homotrimer with asymmetrical radii and separations, which exhibits characteristics of multiple plamonic resonances and different electric field distributions, is systematically investigated by means of 2D finite element method. It was found that the dark and bright modes appear in asymmetrical nanowire homotrimer. In addition, when the dark modes appear between the smaller radii of the nanowires, the cascade effect results in enhanced electric field between the smaller radii nanowires. As a result of the appearance of the bright modes between the smaller radii of the nanowires, the restriction of the cascade effect generates enhanced electric field between the bigger nanowires.
