项目摘要
AbstractNontechnical DescriptionSolar cells, which harvest energy from the sun and generate electricity, are diversifying our energy portfolio and will be an important part of reducing our dependence on fossil fuels and preventing undesirable climate change. It is important to make solar panels as efficient as possible so that the number of panels needed to obtain a certain amount of power can be reduced in order to save on installation costs. Tandem cells, comprised of a top cell that harvests the visible portion of the spectrum and a bottom cell that harvests the infrared portion, are the most promising way to achieve higher efficiencies. Silicon, which is used in approximately 92% of the solar panels that are manufactured each year, is ideal for the bottom cell and typically has 16-21 % efficiency by itself. Perovskite semiconductors are highly attractive for the top cell because they can be tuned to have the right bandgap and have efficiency as high as 22%. The objective of this project is to demonstrate the first 30%-efficient perovskite/silicon tandem solar cell. Technical DescriptionThis project describes plans for a perovskite expert, Professor Michael McGehee, to partner with a silicon expert, Professor Zachary Holman, to make perovskites/silicon tandem solar cells. This team has made a prototype two-terminal monolithic device with a power conversion efficiency of 25.3 %. They hold the world record for this type of device and are in a very strong position to increase the efficiency to 30% over the next two years. This development is especially exciting because their packaged perovskite solar cells have already passed the PV industry standard damp heat and temperature cycling tests and it is likely that panels with these cells could be manufactured at a cost of $100/m2. The bandgap of perovskites can be tuned from 1.2 eV to 2.3 eV using the materials set ABX3, where A is a mixture of methylammonium, formamidinium or cesium, B is a mixture of tin and lead, and X is a mixture of bromine or iodine. The most important research goal of this project is to find the optimal combination of these components for making a stable and high-quality semiconductor with a bandgap of 1.8 eV. The team will thoroughly characterize the semiconductors it makes to guide the process of optimizing the properties. Additional research goals of this project are to develop high-mobility TCO layers for the front of the tandem solar cells, improve the infrared response of the silicon bottom cell while decreasing its cost via a porous dielectric/metal rear reflector, and fabricate PDMS layers with scattering textures to be used at the front of the tandem to reduce reflectance.This project has the potential to change our future energy landscape through the development of efficient yet inexpensive PV technologies. The project will also train a diverse pool of students and the results will be disseminated broadly. Holman is the PI of an NSF REU site into which the proposed project will be integrated. Approximately once every 18 months McGehee gives a lecture that is intended to be easy to understand even for people who are not yet scientists and posts it on YouTube. These lectures are typically viewed more than 20,000 times by a wide variety of people.
摘要非技术描述太阳能电池从太阳获取能量并发电,使我们的能源组合多样化,并将成为减少我们对化石燃料的依赖和防止不良气候变化的重要组成部分。重要的是尽可能提高太阳能电池板的效率,这样才能减少获得一定功率所需的电池板数量,从而节省安装成本。串联电池是实现更高效率的最有希望的方法,它由一个获取可见光谱部分的顶部电池和一个获取红外部分的底部电池组成。每年生产的太阳能电池板中约有92%使用硅,它是底层电池的理想选择,通常本身就有16%-21%的效率。钙钛矿半导体对顶级电池非常有吸引力,因为它们可以调节到具有合适的带隙,效率高达22%。该项目的目标是展示第一个30%效率的钙钛矿/硅串联太阳能电池。本项目描述了钙钛矿专家Michael McGehee教授与硅专家Zachary Holman教授合作制造钙钛矿/硅串联太阳能电池的计划。该团队制作了一台双端单片器件样机,功率转换效率为25.3%。他们保持着这类设备的世界纪录,并处于非常有利的地位,将在未来两年内将效率提高到30%。这一进展尤其令人兴奋,因为他们的封装钙钛矿型太阳能电池已经通过了光伏行业标准的湿热和温度循环测试,使用这些电池的电池板很可能以每平方米100美元的成本制造。使用ABX3材料组,钙钛矿的带隙可以从1.2 eV调节到2.3 eV,其中A是甲铵、甲胺或铯的混合物,B是锡和铅的混合物,X是溴或碘的混合物。本项目最重要的研究目标是找到这些元件的最佳组合,以制造出稳定的、高质量的带隙为1.8 eV的半导体。该团队将对其制造的半导体进行彻底的表征,以指导优化性能的过程。该项目的其他研究目标是开发用于串联太阳能电池正面的高迁移率TCO层,改善硅底电池的红外响应,同时通过多孔介质/金属后反射器降低其成本,并制造具有散射织构的PDMS层,用于串联太阳能电池的前端以降低反射率。该项目有可能通过开发高效而廉价的光伏技术来改变我们未来的能源格局。该项目还将培训一批不同的学生,其成果将广泛传播。霍尔曼是NSF REU网站的PI,拟议的项目将整合到该网站中。McGehee大约每18个月做一次演讲,目的是让那些还不是科学家的人也能理解,并将其发布在YouTube上。这些讲座通常被各种各样的人观看了20,000多次。
