A cost effective and highly-durable wavelength-selective photovoltaic (PV) panel is being developed that simultaneously facilitates plant growth, reduces cooling requirements and generates power at less than $1/watt incremental cost. The greenhouse uses a luminescent sheet laminated to the glass panels with narrow Si photovoltaic strips to selectively absorb the green portion of the solar spectrum that is not used by plants. Green light is then selectively downshifted to red light to match to the photosynthetically active region for plants and the efficiency maximum of Silicon-based photovoltaic cells. The color tuning associated with the conversion of green to red light has been shown to facilitate fruit production in tomatoes and increase flower production. A prototype greenhouse will be built with suitable control to test the technology under 6-months of California aging conditions and which can respond to customer needs. This proposal will create a greenhouse that can be remotely monitored via the web to provide results on both plant growth and the energy production. Creating energy-neutral greenhouses that can pay for themselves in a few years of operation will open up the ability to grow healthy food in locations where it is currently not economically viable due to the local climate of available resources. This product will target the rapidly growing-local food industry that saves natural resources by growing food close to where it is consumed. Natural resources are saved by avoiding food transportation costs, by using the same land to provide both food and electrical energy, and by more efficiently utilizing water resources. The commercialization of this power-generating greenhouse will open up a new avenue for PV deployment and potentially create U.S. based manufacturing jobs by utilizing our existing window production lines and knowledge.

一种具有成本效益且高度耐用的波长选择光伏 (PV) 面板正在开发中，该面板可同时促进植物生长、降低冷却需求并以低于 1 美元/瓦的增量成本发电。 该温室使用层压到带有窄硅光伏条的玻璃面板上的发光板来选择性地吸收太阳光谱中植物未使用的绿色部分。 然后，绿光选择性地降低为红光，以匹配植物的光合作用活跃区域和硅基光伏电池的最大效率。 与绿光到红光转换相关的颜色调节已被证明可以促进西红柿的果实生产并增加花卉产量。 将建造一个具有适当控制的原型温室，以在加州老化条件下测试该技术 6 个月，并能满足客户的需求。 该提案将创建一个可以通过网络远程监控的温室，以提供植物生长和能源生产的结果。创建可在运行几年内收回成本的能源中性温室，将使在目前由于当地气候和可用资源而在经济上不可行的地区种植健康食品成为可能。 该产品将针对快速发展的当地食品工业，通过在消费地附近种植食物来节省自然资源。 通过避免食品运输成本、使用同一块土地提供食品和电能以及更有效地利用水资源，可以节省自然资源。 这种发电温室的商业化将为光伏部署开辟一条新途径，并有可能利用我们现有的窗户生产线和知识创造美国的制造业就业机会。
