This Small Business Technology Transfer (STTR) Phase I project involves the development of a new method for fabrication of nanostructured photovoltaics with ultra-high efficiency. Solar energy conversion using photovoltaics (PVs) is an important energy technology. However, to fully realize solar energy's promise, a significant advance in the current state-of-the-art must still be obtained, such as increasing efficiency and lowering cost per kWh. Synkera will address this need by proposing a new class of fully inorganic photovoltaics. These materials feature innovative 3-D architecture, which combine high surface area arrays of nanojunctions with continuous grading of the band gap to match the solar spectrum. Based on lightweight and low-cost substrates and using scalable processes, this architecture has the potential to achieve conversion efficiencies up to 60%, provide high power density, and enable long-term radiation and temperature stability. The proposed approach will be implemented by combining core expertise and capabilities of Synkera Technologies and the University of Colorado at Boulder. The goal of the Phase I work is to demonstrate that the proposed architecture can enable better performance in comparison with conventional photovoltaic materials.Commercially, the expected result of the proposed work is a manufacturing technology for commercially viable production of low-cost photovoltaics with advanced performance, including ultra-high efficiency and high energy density. Inorganic photovoltaic materials encapsulated in a robust ceramic host will assure greater radiation stability, as well as superb thermal and mechanical reliability. Enabling these benefits will provide significant advantages in the marketplace and an opportunity to serve terrestrial solar energy markets in commercial, governmental and military markets, with the residential energy generation dominating the market share. Furthermore, robustness of proposedmaterials makes them also attractive for use in growing satellite market. This new manufacturing technology will contribute to strengthening the US economy by helping to create a robust and globally competitive domestic solar cell industry. It will also contribute to the Nation's security by reducing our dependence on non-renewable energy supplies.

这项小型企业技术转让（STTR）第一阶段项目涉及开发一种制造超高效率纳米结构光伏电池的新方法。利用光伏进行太阳能转换是一项重要的能源技术。然而，要充分实现太阳能的前景，必须在当前最先进的技术上取得重大进展，例如提高效率和降低每千瓦时成本。Synkera将通过提出一种新型的全无机光伏电池来满足这一需求。这些材料具有创新的三维结构，结合了高表面积的纳米结阵列和连续分级的带隙，以匹配太阳光谱。基于轻量化和低成本的基板，并使用可扩展的工艺，该架构有可能实现高达60%的转换效率，提供高功率密度，并实现长期辐射和温度稳定性。拟议的方法将通过结合Synkera Technologies和科罗拉多大学博尔德分校的核心专业知识和能力来实施。第一阶段工作的目标是证明与传统光伏材料相比，所提出的架构可以实现更好的性能。在商业上，这项工作的预期结果是一种商业上可行的低成本光伏电池生产技术，具有先进的性能，包括超高效率和高能量密度。无机光伏材料封装在坚固的陶瓷主机中，将确保更高的辐射稳定性，以及出色的热学和机械可靠性。实现这些好处将在市场上提供重大优势，并有机会为商业、政府和军事市场的地面太阳能市场提供服务，其中住宅能源发电占市场份额的主导地位。此外，拟议材料的坚固性使它们在不断增长的卫星市场中也具有吸引力。这种新的制造技术将有助于建立一个强大的、具有全球竞争力的国内太阳能电池产业，从而加强美国经济。它还将通过减少我们对不可再生能源供应的依赖，为国家安全做出贡献。
