Abstract

Solar energy is indispensable and needs to be developed to meet the future energy demands of the world. One of the impediments to this technology is the low efficiency of the solar module, the glass shield being one of the reasons. At present, solar modules suffer from 4% transmission loss at the air/glass interface (at normal incidence) which increases with an increase in the accumulation of dust particles. Hence, in this paper techniques have been presented to reduce the transmission loss in solar modules as well as to keep them clean. Nanopatterning of the glass shield surface exhibited an increase of ~3% in optical transmission as well as an improvement in omnidirectional antireflective behaviour. A solar module was also fabricated which exhibited an improvement of ~6% in the efficiency with the nanopatterning of packaging glass cover. Perfluorodecyltriethoxysilane (PFTS) and Titanium dioxide (TiO2) coatings have been employed for self-cleaning applications. Setup and performance of a 10 kW photovoltaic system has also been discussed.

太阳能电池封装用纳米图案和自清洁玻璃基板
太阳能是不可或缺的,需要发展,以满足未来世界的能源需求。这项技术的障碍之一是太阳能组件的低效率,玻璃屏蔽是原因之一。目前,太阳能组件在空气/玻璃界面(在正常入射下)遭受4%的透射损失,随着尘埃颗粒积累的增加而增加。因此,本文提出了减少太阳能组件传输损耗并保持其清洁的技术。玻璃屏蔽表面的纳米图案显示出光透射率提高了约3%,并且改善了全向抗反射性能。采用封装玻璃盖的纳米图案,可使太阳能组件的效率提高约6%。全氟癸基三乙氧基硅烷(PFTS)和二氧化钛(TiO2)涂层已被用于自清洁应用。本文还讨论了10kw光伏系统的设置和性能。
