The UK is committed to achieve net zero carbon emissions by 2050. This will require a massive shift in the way electricity is generated, away from burning fossil fuels and towards the use of renewable sources such as wind and solar. The cost of solar modules has reduced dramatically over the past few years and subsidy-free deployment is expanding rapidly, especially at utility scale. It is forecast that more than 40GW will be in use in the UK by 2030. Solar assets are financed by professional managers who are concerned by the ongoing operational costs of maintenance that affect power output and the return on investment. In particular, attention is being drawn to the problem of cover glass soiling that attenuates the light into the module. Soiling can reduce power output by up to 5% in the UK and is a far more serious problem (up to 50%) in arid sunbelt regions such as occur in India and the Middle East. Polymer-based hydrophobic anti-soiling coatings have been shown to work in principle, but their durability is not sufficient to withstand 24/7 exposure to environmental stresses or to abrasion damage caused by regular cleaning. The objective of this research is to develop and test a thin inorganic rare-earth oxide coating for application to solar cover glass. The hydrophobic coating will be low surface energy to reduce the adhesion to soiling. Its application will reduce the frequency of costly cleaning cycles. The coating will be capable of being applied at industrial scale using an Atmospheric Chemical Vapour Deposition process that is compatible with glass manufacturing. Use of the coating will significantly improve the practical power output of solar modules and will have worldwide impact.

英国承诺到2050年实现净零碳排放。这将需要发电方式的巨大转变，从燃烧化石燃料转向使用风能和太阳能等可再生能源。太阳能组件的成本在过去几年中大幅下降，无补贴部署正在迅速扩大，特别是在公用事业规模。预计到2030年，英国的使用量将超过40 GW。太阳能资产由专业管理人员提供资金，他们关心影响电力输出和投资回报的持续运营维护成本。特别是，注意力被吸引到盖板玻璃污染的问题，衰减进入模块的光。在英国，土壤污染会使发电量减少5%，在印度和中东等干旱的阳光地带，土壤污染是一个更为严重的问题（高达50%）。基于聚合物的疏水防污涂料已被证明在原则上起作用，但它们的耐久性不足以承受24/7暴露于环境应力或由定期清洁引起的磨损损坏。本研究的目的是开发和测试一种薄的无机稀土氧化物涂层应用于太阳能盖板玻璃。疏水涂层将是低表面能的，以减少对污物的粘附。它的应用将减少昂贵的清洁周期的频率。该涂层将能够使用与玻璃制造兼容的大气化学气相沉积工艺以工业规模应用。该涂层的使用将显著提高太阳能电池组件的实际功率输出，并将产生全球影响。
