Enhanced solar energy harvesting in dye sensitized solar cells using nanophosphors and nano-structured optics (CONVERTED)

在过去的20年里，用于发电的光伏太阳能电池（PV）已经催生了一个行业，该行业专注于不断改进材料，以更有效地利用可用的太阳能。随着效率接近12%，由于多层材料、异形表面、薄膜技术等对碳经济产生了巨大的积极影响，人们一直在努力提高效率。在最近完成的TSB项目中，CONVERT (TSB ref. AE100D)，目前联盟的两个合作伙伴（布鲁内尔大学的沃尔夫森中心和intrinq材料有限公司）开发了长寿命的下转换荧光粉，一旦在示范中得到验证，将在全球范围内用于涂料和电池，以将更多的太阳能量转移到首选的光伏频率。在这个项目中，我们将扩大可持续能源服务的规模，以展示增加可用自然能源的效果，从而提高能源产出。此外，我们将从G24i当前电池表面浪费的三分之一收集光，并将光重新定向到电池的活跃区域，从而旨在实现约25%的性能增益。

Over the last 20 years, photovoltaic solar cells (PV) for power generation have spawned an industry that focuses on continuously improving materials to use the solar energy that is available more efficiently. With efficiencies approaching 12%, huge effort has been focused onto improving efficiency by using multi-layer materials, profiled surfaces, thin film technologies etc due to the huge positive impact they have on the carbon economy. On a recently completed TSB programme, CONVERT (TSB ref. AE100D), two of the partners of the present consortium (the Wolfson Centre at Brunel University and Intrinsiq Materials Ltd) developed long-life down-converting phosphors that, once proven by scaling up in demonstrators, will be used worldwide in coatings and on cells to transfer more of the sun's energy into preferred PV frequencies. In this project we will scale up DSSCs to show the effect of augmenting the natural energy available and hence enhance energy output. In addition, we will harvest the light from a third of G24i's current cell's surface that is wasted and redirect the light to the active regions of the cell, thereby aiming to achieve performance gains of ca. 25%.
