项目摘要

The harvesting of sunlight has the potential to revolutionize the way mankind generates electricity. At present however, only a small fraction (0.02% in 2008) of the world's total electrical power is generated using sunlight. Photovoltaic (PV) installations based on crystalline silicon are an increasingly popular way of generating electricity from solar-radiation, however such installations suffer from a relatively long pay-back time resulting from their high cost of manufacture. There is thus growing interest in the development photovoltaics based on organic (polymeric) materials (OPV) that can in principle be produced at low-cost, over very large areas utilizing solution-based processes that do not require a large energy input. At present however, even the best lab-based OPVs have an efficiency that is significantly lower than that of standard crystalline silicon (~8% compared with ~18%), coupled with a relatively short operational lifetime - attributes that have partly precluded their commercialization. There is nevertheless great interest in exploring the scale-up of OPVs, despite the fact that no common consensus has been reached on the best route to deposit multilayer architectures at high-speed. This problem is compounded by the fact that many of the materials that have the highest efficiency in OPV devices often have rather low solubility; properties that limit their application in high-speed manufacture processes. Addressing these issues lies at the heart of our proposed research. Firstly, we will engineer the chemical structure of state-of-the-art low energy-gap donor polymers to significantly improve their solubility and processability. We will then explore the deposition of such materials into OPVs using spray-based techniques. The thin-films formed will be characterized using high-resolution electron microscopy together with X-ray and neutron-scattering. The project team we have assembled for this task have leading expertise in organic-electronics, polymer-synthesis, polymer-physics and practical manufacturing processes. Our project is significantly strengthened by funds from the European Regional Development Fund (Project Mercury) to purchase an automated aerosol deposition system and fund postdoctoral and postgraduate researchers. We have ready route for commercialization via our (unfunded) links with a TSB-funded project that intends to develop OPVs for transparent window-glass applications. We anticipate the outcome of our work will be a materials set and a scalable process for high speed OPV manufacture.We will gain impact for our work through showcasing scaled-up OPV devices at the Sheffield Solar Farm and by interacting with artists and designers who wish to use organic photovoltaics in their work. We will also gain valuable support and publicity for our work through 'Project Sunshine'; a flagship project at Sheffield that promotes research into the utilization of solar energy to solve problems related to mankind's growing energy-needs and food-production in a time of growing climate uncertainty.

太阳光的收集有可能彻底改变人类发电的方式。然而，目前世界总电力中只有一小部分（2008年为0.02%）是利用太阳能发电的。基于晶体硅的光伏（PV）装置是从太阳辐射发电的日益流行的方式，然而，由于其高制造成本，这种装置遭受相对长的投资回收时间。因此，人们对基于有机（聚合）材料（OPV）的光致发光材料的开发越来越感兴趣，该光致发光材料原则上可以利用不需要大量能量输入的基于溶液的方法在非常大的区域上以低成本生产。然而，目前，即使是最好的实验室OPV的效率也明显低于标准晶体硅的效率（约8%与约18%），加上相对较短的使用寿命-这些属性部分阻碍了其商业化。尽管事实上在高速存款多层结构的最佳途径上还没有达成共识，但人们对探索OPV的规模化有很大的兴趣。这个问题由于以下事实而变得复杂：在OPV器件中具有最高效率的许多材料通常具有相当低的溶解度;限制它们在高速制造过程中的应用的特性。解决这些问题是我们拟议研究的核心。首先，我们将设计最先进的低能隙供体聚合物的化学结构，以显着改善其溶解性和加工性。然后，我们将探索使用喷雾技术将这些材料沉积到OPV中。将使用高分辨率电子显微镜以及X射线和中子散射来表征形成的薄膜。我们为这项任务组建的项目团队在有机电子、聚合物合成、聚合物物理和实际制造工艺方面拥有领先的专业知识。我们的项目得到了欧洲区域发展基金（Project Mercury）的资助，用于购买自动气溶胶沉积系统并资助博士后和研究生研究人员。我们已经准备好了商业化的路线，通过我们的（无资金）与TSB资助的项目，旨在开发透明窗玻璃应用的OPV的联系。我们预计我们的工作成果将是一套材料和一个可扩展的工艺，用于高速OPV制造。我们将通过在谢菲尔德太阳能农场展示按比例放大的OPV设备，并通过与希望在工作中使用有机光致发光材料的艺术家和设计师互动，为我们的工作带来影响。我们还将通过“阳光项目”为我们的工作获得宝贵的支持和宣传;这是谢菲尔德的一个旗舰项目，旨在促进对太阳能利用的研究，以解决与人类在气候日益不确定的时期日益增长的能源需求和粮食生产有关的问题。
