High-efficiency Hybrid Solar Cells for Micro-generation

为了满足不断变化的能源需求，光伏发电的广泛应用需要光伏发电成本的逐步变化。该提案汇集了来自曼彻斯特大学和伦敦帝国理工学院伦敦的化学家，物理学家，材料科学家和电气工程师的联盟，通过开发新的低成本，高效率，示范太阳能电池的微型generation.We提出了新的设计混合有机/无机器件集成的灵活性和稳定性与廉价的材料和解决方案为基础的处理，以满足这一需求。在一种设计中，半导体量子点（QD）被用作高迁移率有机空穴传输体和定向金属氧化物纳米棒阵列之间的界面处的光吸收体，所述定向金属氧化物纳米棒充当电子传输体。光学和电子特性的独立优化将导致最大化功率转换效率的设计规则。在第二种设计中，将优化具有新型金属氧化物电极的混合聚合物/QD共混物太阳能电池。该提案首次在同一设备概念中结合了超高效率和超低成本的新方法。我们的目标是构建负担得起的示范混合太阳能电池，可以大规模生产，长期潜力，以实现10%的能源转换效率。

Widespread implementation of photovoltaic electricity to meet changing energy demands requires a step-change in the cost of photovoltaic power. This proposal assembles a consortium of chemists, physicists, materials scientists and electrical engineers from The University of Manchester and Imperial College London to address this need through the development of new low-cost, high-efficiency, demonstration solar cells for micro-generation.We propose new designs for hybrid organic/inorganic devices which integrate flexibility and stability with inexpensive materials and solution based processing. In one design, semiconductor quantum dots (QDs) are used as the light absorber at the interface between a high mobility organic hole transporter and an array of directed metal oxide nano-rods, which act as the electron transporter. Independent optimisation of the optical and electronic properties will lead to design rules for maximising power conversion efficiency. In a second design, hybrid polymer/QD blend solar cells with novel metal oxide electrodes will be optimised. This proposal combines new approaches for ultra high efficiency with ultra low cost in the same device concept for the first time. Our aim is to construct affordable demonstration hybrid solar cells that could be mass-produced with long-term potential to achieve energy conversion efficiency of 10%.
