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

在过去的20年里，用于发电的光伏太阳能电池（PV）已经发展成为一个专注于获得更好的材料以更有效地利用可用太阳能的行业。随着效率接近10%，人们一直在努力通过使用多层材料和薄膜技术（如DSSC）来提高效率，以提高性能，因为它们对碳经济及其下游可扩展性产生了巨大的积极影响。之前的一个项目（CONVERT）开发了长寿命的下转换荧光粉，可用于电池和涂层，将更多的太阳能转换为首选的光伏频率-在TSB DSSC大挑战项目中，我们将致力于采用这些创新材料并开发优化的DSSC方法。我们的目标是将联合收割机与增强的光处理技术相结合，以使用更多的太阳能，这些太阳能会击中DSSC的非转换部分，该部分可以达到总面积的30%。通过结合这两种适用于所有电池的技术，我们的目标是增强Grand Challenge光伏系统，并将供应链的第一部分准备就绪，以便在英国生产和扩大规模。

Over the last 20 years, photo voltaic solar cells (PV) for power generation has grown an industry that focuses on getting better materials to more efficiently use the solar energy that is available. With efficiencies approaching 10%, huge effort has been focused onto improving efficiency by using multi layer materials & thin film technologies such as DSSC to improve performance due to the huge positive impact they have on the carbon economy and on their downstream scalability. A previous programme (CONVERT) developed long life down converting phosphors that could be used in cells and coatings to transfer more of the suns energy into preferred PV frequencies - in this TSB DSSC Grand Challenges programme, we will aim to take these innovative materials and develop an optimised DSSC approach. We aim to combine this with enhanced light handling technology to use more of the suns energy that hits the non converting part of the DSSC which can be up to 30% of the total area. By combining these two techniques, applicable to all cells, we aim to enhance the Grand Challenge PV systems and put a the first part of a supply chain in place ready for production and scale up in the UK.
