The broader impact/commercial potential of this Partnerships for Innovation - Technology Translation (PFI-TT) project is to enable solar cell use on water rather than just on land. The growth of solar photovoltaic energy has highlighted the increasing problem of competing land use, scarcity, and cost. Floating photovoltaics have emerged as a solution to this problem; deploying solar modules on existing bodies of water lessens the need for land-based installations. However, the high cost has inhibited growth of this renewable energy source. This project advances a new system that is lighter and cheaper. Furthermore, the modules are fabricated with non-toxic and environmentally friendly materials, mitigating the risk posed by other novel photovoltaic technologies of contaminating the bodies of water. The proposed project advances lower cost lightweight alternatives for solar photovoltaic generation. This hybrid photovoltaic technology combines innovative polymer science with silicon, the most abundant and significant photovoltaic material in use today, to provide cheaper, lighter, and more efficient flexible modules. Recent computer model simulations indicate that the proposed polymer deposition method (oxidative chemical vapor deposition) generates high conductivity and when coupled with an optimized surface treatment of silicon, the power efficiencies can exceed 20%. Furthermore, this hybrid approach allows the polymer to mechanically support the brittle silicon substrate, enabling the fabrication of flexible modules (to address wind load) encapsulated by plastic films rather than glass panels. This project validates the high efficiency, mechanical robustness, and durability under accelerated degradation conditions of the hybrid photovoltaic technology and creates a prototype for testing in a relevant environment.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这种创新合作伙伴关系的更广泛的影响/商业潜力 - 技术翻译（PFI -TT）项目是在水上而不是在陆地上实现太阳能电池的使用。太阳能光伏能源的增长强调了竞争土地使用，稀缺和成本的越来越多的问题。浮动光伏已经作为解决此问题的解决方案。在现有水域上部署太阳能模块可以减少对陆基装置的需求。但是，高成本抑制了这种可再生能源的增长。 该项目推动了一个更轻，更便宜的新系统。此外，这些模块是用无毒和环保的材料制造的，可减轻其他新型的光伏技术污染水体的风险。拟议的项目推进了太阳能光伏生成的较低成本轻巧的替代方案。这种混合光伏技术将创新的聚合物科学与硅（当今最丰富，最重要的光伏材料）结合在一起，以提供更便宜，更轻，更有效的柔性模块。最近的计算机模型模拟表明，所提出的聚合物沉积法（氧化化学蒸气沉积）会产生高电导率，并且与优化的硅表面处理相结合时，功率效率可能超过20％。此外，这种混合方法使聚合物能够机械支撑脆性硅底物，从而使柔性模块（以解决由塑料膜而不是玻璃面板封装的风负载）的制造。该项目验证了混合光伏技术的加速降解条件下的高效率，机械鲁棒性和耐用性，并创建了在相关环境中进行测试的原型。该奖项反映了NSF的法定任务，并通过使用该基金会的知识分子的优点和广泛的影响来评估NSF的法定任务，并被视为值得进行的支持。
