由于太阳在天空中的运动，宽带和全方位的采光是光伏技术的重大发展。本文报道了在铜(In，Ga)Se-2(CIGS)太阳电池上制备柔性织构聚二甲基硅氧烷(PDMS)薄膜的方法，这是制备三维结构的最简单和最廉价的剥离工艺之一。含有织构的PDMS薄膜的电池在模拟单日照场景中将短路电流密度从22.12 mA/cm(2)提高到23.93 mA/cm(2)。还研究了含不同PDMS膜的CIGS太阳电池的全方位减反射性能。本研究使用角度分辨反射光谱仪来研究所提出的PDMS薄膜的全向和宽带光学性质。这种捕光能力的提高归功于PDMS薄膜的散射和PDMS微结构与空气之间的渐变折射率分布。这种具有柔性纹理的PDMS薄膜适合于为各种光伏设备创建减反射涂层。(C)2014年美国光学学会
Because of the Sun's movement across the sky, broadband and omnidirectional light harvesting is a major development in photovoltaic technology. This study reports the fabrication and characterization of flexible-textured polydimethylsiloxane ( PDMS) film on Cu(In,Ga)Se-2 (CIGS) solar cells, which is one of the simplest and cheapest peel-off processes for fabricating a three-dimensional structure. A cell containing a textured PDMS film enhanced the short-circuit current density from 22.12 to 23.93 mA/cm(2) in a simulated one-sun scenario. The omnidirectional antireflection of CIGS solar cells containing various PDMS films is also investigated. This study uses an angle-resolved reflectance spectroscope to investigate the omnidirectional and broadband optical properties of the proposed PDMS film. This improvement in light harvesting is attributable to the scattering of the PDMS film and the gradual refractive index profile between the PDMS microstructures and air. The flexible-textured PDMS film is suitable for creating an antireflective coating for a diverse range of photovoltaic devices. (C) 2014 Optical Society of America
