Efficient adoption of sustainable energy and realization of better environments are listed as major global challenges. Solar energy conversion to electricity is the most feasible approach to meet the ever increasing, urgent energy demand of humanity without adverse environmental impacts. On the other hand, effective removal of pollutants from waste water via solar photocatalysis is of significant environmental importance. Nonetheless, achieving low-cost, high-efficiency photovoltaic (PV) devices (which will allow their large scale implementation worldwide) and efficiently harvesting solar energy for photocatalysis remain very challenging. Nanomaterials (size scale: 1-100 nm) with their novel properties unique to matter of such dimensions are offering new ways to address pressing energy and environment issues. In particular, quantum dots (QDs) and catalytic nanostructures, hold high potential for PV and photocatalysis applications, respectively. On the other hand, plasmonic nanostructures (e.g. Au and 2) rationally design plasmonic nanostructures and realize plasmon/semiconductor-catalyst architectures in order to develop broadband (UV-to-NIR), high-efficiency photocatalysis systems and understand exact mechanism(s).The proposed research will lead to the development of new nanohybrids with excellent performance in PVs and photocatalysis and increase our knowledge on multiple aspects of plasmon enhanced PVs and photocatalysis. Not only can it pave the way to technological breakthroughs, it will also promote the training of highly qualified personnel to respond to the scientific and technological challenges of our modern society.

有效采用可持续能源和实现更好的环境被列为主要的全球挑战。太阳能转换为电能是满足人类日益增长、紧迫的能源需求且不对环境造成不利影响的最可行方法。另一方面，通过太阳能光催化有效去除废水中的污染物具有重要的环境重要性。尽管如此，实现低成本、高效率的光伏（PV）装置（这将使其能够在全球范围内大规模实施）并有效收集太阳能用于光催化仍然非常具有挑战性。纳米材料（尺寸范围：1-100 nm）具有此类尺寸物质特有的新颖特性，为解决紧迫的能源和环境问题提供了新的方法。特别是，量子点（QD）和催化纳米结构分别在光伏和光催化应用中具有很高的潜力。另一方面，等离激元纳米结构（例如Au和2）合理设计等离激元纳米结构并实现等离激元/半导体催化剂结构，以开发宽带（UV-NIR）、高效光催化系统并了解确切的机制。所提出的研究将导致开发在光伏和光催化方面具有优异性能的新型纳米杂化物，并增加 我们在等离子体增强光伏和光催化等多个方面的知识。它不仅可以为技术突破铺平道路，还将促进高素质人才的培养，以应对现代社会的科技挑战。
