Enhancing photon absorption by light trapping is an important way to improve efficiency of photovoltaic devices. In this work, we discuss one such method called aluminium induced texturization (AIT) which can help textured glass act as a scattering element in solar cells and introduce a sustainable fabrication method by understanding the different parameters that can control the texturization. The optical properties of AIT glass were studied using UV–VIS-NIR spectrophotometer which shows the haze of these textured glass is directly related to the surface roughness which can be tuned by thickness of Aluminium deposited. We have done a comparative study of acidic and alkaline etching techniques optimized for lower thermal budget and lesser operational hazard by eliminating concentrated (49%) hydrofluoric acid in the process. Investigation of the surface topography using atomic force microscopy and scanning electron microscopy corroborates the change in haze that comes from the change in rms roughness due to differences in surface morphology from different etch conditions. The AIT glass we developed has a high transmittance (~93%), peak haze value between (70%-25%) and rms roughness between 40 and 190 nm which can be tuned by changing the aluminium thickness and etch conditions. A proof of concept of forming superpositioned texture in combination with transparent conducting oxides to use the AIT glass as an active component of the device has also been elucidated.

碱性和酸性蚀刻在铝诱导的太阳能电池用玻璃玻璃中的功效研究

通过光捕获来增强光子吸收是提高光伏器件效率的重要途径。在这项工作中,我们讨论了一种称为铝诱导织构化(AIT)的方法,该方法可以帮助纹理化玻璃充当太阳能电池中的散射元素,并通过了解可以控制织构化的不同参数来介绍一种可持续的制造方法。使用UV-VIS-NIR分光光度计研究了AIT玻璃的光学性能,结果表明这些纹理玻璃的雾度与表面粗糙度直接相关,可以通过沉积铝的厚度来调节其粗糙度。我们已经对酸性和碱性蚀刻技术进行了比较研究,该技术通过消除工艺中的浓(49%)氢氟酸而优化了热预算,降低了操作风险。使用原子力显微镜和扫描电子显微镜对表面形貌的研究证实了雾度的变化,该雾度的变化是由于不同蚀刻条件下表面形态的差异而导致的均方根粗糙度的变化。我们开发的AIT玻璃具有很高的透射率(〜93%),雾度峰值介于(70%-25%)之间,均方根粗糙度介于40至190 nm之间,可以通过改变铝的厚度和蚀刻条件来进行调整。还已经阐明了形成透明纹理并与透明导电氧化物结合使用AIT玻璃作为设备活性成分的概念证明。
