Development of Prototype High Efficiency Multi-Junction Organic Solar Cells

有机光电池（OPV）是新兴的第三代太阳能电池技术，其提供了非常低的成本制造和利用环境可持续材料和工艺生产轻质模块的前景。OPV提供了真正的中长期前景，可将光化学品（PV）的成本降低到远低于每瓦1美元（峰值）的商业重要阈值。此外，OPV与各种基材（包括塑料和金属）的兼容性意味着可以解决现有第一代和第二代PV技术难以满足的新电源应用。因此，OPV将加速光伏技术的市场渗透，并在英国创造新的制造和商业机会。在这个合作研发项目中，一个由工业和大学团体组成的联盟将使用我们的专利多结电池技术开发原型OPV电池。纳米结构的有机和无机材料将被纳入多结电池，然后将被优化，以展示高性能特性（效率和稳定性）以及与低成本，大面积制造的兼容性。该项目的一个关键目标是将新的透明导电电极纳入多结电池技术，从而消除对氧化铟锡（ITO）的需求，并使新技术能够克服低成本制造的关键障碍之一。原型电池将被开发，证明认证的功率转换效率为8%，加速寿命相当于3年的领域，和10厘米× 10厘米的有效电池面积。这些原型将展示与后续产品制造和商业化兼容的性能特征。我们联盟中的工业专业知识将集中于我们在汽车行业和建筑一体化方面的长期产品开发战略。

Organic photovoltaics (OPVs) are an emerging third generation solar cell technology which offer the prospect of very low cost manufacture and the production of lightweight modules that utilise environmentally sustainable materials and processes. OPVs offer genuine medium to long term prospects for reducing the cost of photovoltaics (PVs) well below the commercially important threshold of $1 per watt (peak). In addition, the compatibility of OPVs with a wide range of substrates, including plastics and metals, means that new power applications can be addressed which are not easily met by existing first and second generation PV technologies. OPVs will therefore accelerate market penetration of PV technology as well as enabling new manfacturing and business opportunities within the UK. In this collaborative R@D project a consortia of industry and university groups will develop prototype OPV cells using our patented multi-junction cell technology. Nanostructured organic and inorganic materials will be incorporated into multi-junction cells which will then be optimised to demonstrate high performance characteristics (efficiency and stability) as well as compatibility with low cost, large area fabrication. A key objective of this project will be to incoporate new transparent conducting electrodes into the multi-junction cell technology, thus eliminating the requirement for indium tin oxide (ITO) and enabling the new technology to overcome one of the key obstacles to low cost manufacture. Prototype cells will be developed that demonstrate certified power conversion efficiencies of 8%, accelerated lifetimes equivalent to 3 years in the field, and active cell areas of 10 cm x 10 cm. These prototypes will demonstrate performance characteristics compatible with subsequent product manufacture and commercialisation. The industrial expertise in our consortia will focus our strategy for longer term product development in the automotive sector and building integration.
