Objectives of the proposed research is to develop and demonstrate a design methodology for integrating advanced holographic spectral filtering, concentrating, and light trapping properties in holographic components that increase the efficiency and energy collection properties of thin film photovoltaic systems. Another objective is to realize candidate holograms film layers on flexible substrates that can be laminated with either standard photovoltaic module components or in non-traditional conformal geometries. This approach does not add complexity to the thin film PV cell structure. Instead the hologram is used as a design option to improve the performance of thin film PV cells. Intellectual Merit consists of advancing the state of non-imaging holographic element design to realize low cost planar concentrators and light trapping techniques. Holographic element design methodologies will be integrated with thin film photovoltaic cell properties to improve thin film PV cell efficiency. Broader Impacts: The proposed work addresses one of the most important issues of our time ?reducing the cost of renewable solar energy. If successful the proposed work will impact the cost of photovoltaic energy in the near future (5-10 years) when it is most needed to mitigate global warming.The realization of low cost PV systems will also allow electrical energy to be available in rural and remote areas not served by a power grid. This will allow lighting, irrigation, and desalination in many underserved communities bringing more opportunity to third world populations. The proposed work offers students the opportunity to participate in a range of photovoltaic energy problems. This will provide them with the necessary background to transition to industry or to pursue academic careers in solar energy related fields.

拟议的研究的目标是开发和展示一种设计方法，用于集成先进的全息光谱过滤，集中和光捕获特性的全息组件，提高薄膜光伏系统的效率和能量收集性能。另一个目的是在柔性基板上实现候选全息图膜层，该柔性基板可以与标准光伏模块组件层压在一起或以非传统的保形几何形状层压。这种方法不会增加薄膜PV电池结构的复杂性。相反，全息图被用作设计选项，以提高薄膜PV电池的性能。智力上的优点包括推进非成像全息元件设计的状态，以实现低成本的平面聚光器和光捕获技术。全息元件设计方法将与薄膜光伏电池特性相结合，以提高薄膜光伏电池的效率。更广泛的影响：拟议的工作解决了我们这个时代最重要的问题之一？降低可再生太阳能的成本。如果成功的话，这项工作将在不久的将来（5-10年）影响光伏能源的成本，因为这是缓解全球变暖最需要的。低成本光伏系统的实现也将使农村和偏远地区的电网无法提供电能。这将使许多服务不足的社区能够获得照明、灌溉和海水淡化，为第三世界人口带来更多机会。拟议的工作为学生提供了参与一系列光伏能源问题的机会。这将为他们提供必要的背景，过渡到工业或追求在太阳能相关领域的学术生涯。
