ENGINEERED HIERARCHICAL NANOSTRUCTURES FOR OPTIMISED HYBRID PHOTOVOLTAIC DEVICES

该项目的总体目标是在中观和宏观尺度上生成具有定义架构的分层结构，以优化有机-无机混合太阳能电池的效率。为了使太阳能更经济可行，需要逐步改变使用太阳能电池生产的电力成本。为了实现太阳能经济性的这种突破，有必要显着提高光伏器件的性价比。在这个大挑战中，我们打算开发新的混合电池，由廉价的无机电子传输基质和容易制造的有机分子组成，既吸收光又传输空穴。通过设计纳米级材料之间的界面，电池的效率将最大化。在我们开发混合电池的过程中，一个关键的考虑因素是最大限度地减少规模和生产成本。我们提出的路线是基于太阳能电池的每个组件的顺序溶液处理;低温和低压;最小的浪费和低技术。该方法是继承可扩展的，并且容易集成到当前的制造工艺中，包括卷对卷技术。我们的大挑战是开发无机-有机-混合光伏电池，通过纳米级的界面工程，它比目前可用的设备更具成本效益。该计划将是伦敦帝国理工学院伦敦纳米技术中心和沃里克大学之间的合资企业。与新西兰McDairmid高级材料和纳米技术研究所的同事（特别是在沉积过程建模领域）和英国柯达公司（与扩大活动有关）进行了合作。该项目团队具有独特的优势，可以利用纳米结构无机物和有机半导体小分子加工的最新发展;并汇集了这样一个跨学科计划所需的一系列复杂技术。

The overall aim of this project is to generate hierarchical structures with defined architectures at both the meso and macro scale, in order to optimise the efficiency of organic-inorganic hybrid solar cells. To make solar energy more economically viable requires a step-change in the cost of electricity produced using solar cells. To achieve such a disruption in the economics of solar energy it is necessary to significantly improve the cost perfomance ratio of photovoltaic devices. In this Grand Challenge we intend to develop novel hybrid-cells consisting of cheap inorganic electron transport matrices and readily manufactured organic molecules that both absorb light and transport holes. The efficiency of the cells will be maximized by engineering the interface between the materials on the nanoscale. A key consideration throughout our development of hybrid-cells will be the minimization of scale-up and production costs. The route we propose is based on sequential solution processing of each component of the solar cell; low temperature and pressure; minimal waste and low tech. The approach is inhernetly scalable and readily intergarted into current manufacturing practises inlcuding roll-to-roll technology. Our Grand Challenge is to develop inorganic-organic-hybrid-photovoltaic cells which through interface engineering at the nanoscale are significantly more cost effective than currently available devices.The programme will be a joint venture btween the London Centre for Nanotechnology at Imperial College London and Warwick Univeristy. Collaborations are in place with Colleaugues from the McDairmid Institute for Advanced Materials and Nanotechnology in NZ (specifically in the area of modelling of deposition processes) and with Kodak, UK (with links to scale-up activity). The project team are uniquely placed to capitalise on recent developments in the processing of nanostructured inorganics and in organic semiconductor small molecules; and brings together the range of complimetnary techniques required for such an interdisciplinary programme.
