FIG - Flux Increasing Glass to enhance photovoltaic efficiency

在过去10年中，硅光伏发电的成本已大幅下降至每峰值瓦特约0.5美元，如果要实现电网均衡，还需要进一步下降，但在此期间，最好的实验室硅电池的效率几乎没有提高，因为在26%的效率下，它们已经得到了很好的优化，接近29%的理论效率限制。该项目旨在开发一种用于太阳能组件盖玻璃的涂层，该涂层能够将高能蓝光和绿光的光子分裂为两个红外光子。这种光子通量的增加增加了发电量，使平均效率的硅模块的效率增加了4%，并降低了太阳能生产的成本。使这成为可能的新材料技术刚刚被证明在单层涂层中是可行的。在这个项目中，该联盟的目标是显著提高该技术的效率，开发一种在玻璃上涂覆该技术的工艺，并证明该技术在层压到硅太阳能电池后仍然可以运行。

The cost of silicon photovoltaics has fallen dramatically over the last 10 years to around 0.5$ per peak Watt of generating capacity and needs to fall further if grid parity is to be achieved but the efficiency of the best laboratory silicon cells has hardly increased during that period because, at 26% efficient, they are already well optimised and close to the theoretical efficiency limit of 29%. This project aims to develop a coating for solar module cover glass that is able to split photons of high-energy blue and green light into two infra-red photons. This increase in photon flux increases the amount of electricity generated, adding up to 4% to the efficiency of a silicon module of average efficiency and reducing the cost of the solar energy produced. The new materials technology that makes this possible has just been demonstrated to be feasible in a single-layer coating. In this project, the consortium aims to significantly improve the efficiency of the technology, to develop a process for coating it on glass and to show that it can remain operational after lamination to silicon solar cells.
