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.

收集阳光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%）是利用阳光发电的。基于晶体硅的光伏（PV）装置是一种越来越流行的利用太阳辐射发电的方式，但由于制造成本较高，此类装置的投资回收期相对较长。因此，人们对开发基于有机（聚合）材料（OPV）的光伏发电越来越感兴趣，这种光伏发电原则上可以利用基于溶液的工艺在非常大的面积上以低成本生产，不需要大量的能量输入。然而，目前，即使是最好的基于实验室的 OPV 的效率也明显低于标准晶体硅的效率（~8% 与~18%），而且使用寿命相对较短，这些属性在一定程度上阻碍了其商业化。尽管对于高速沉积多层结构的最佳途径尚未达成共识，但人们对探索 OPV 的规模化仍抱有极大的兴趣。由于许多在 OPV 器件中具有最高效率的材料通常具有相当低的溶解度，这一事实使这个问题变得更加复杂。这些特性限制了它们在高速制造过程中的应用。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，以显着提高其溶解度和加工性能。然后，我们将探索使用喷雾技术将此类材料沉积到 OPV 中。所形成的薄膜将使用高分辨率电子显微镜以及 X 射线和中子散射进行表征。我们为此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（水星计划）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，从而大大加强了我们的项目。通过与 TSB 资助的项目（旨在开发用于透明窗玻璃应用的 OPV）的（无资金）联系，我们已准备好商业化路线。我们预计我们的工作成果将是用于高速 OPV 制造的材料集和可扩展流程。我们将通过在谢菲尔德太阳能发电厂展示按比例放大的 OPV 设备以及与希望的艺术家和设计师互动，为我们的工作带来影响。在他们的工作中使用有机光伏发电。我们还将通过“阳光工程”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，以解决在气候不确定性日益增加的情况下与人类不断增长的能源需求和粮食生产相关的问题。
