加州大学圣地亚哥分校（University of California San Diego）获得了一项金额为 250,000 美元的项目，项目名称是 “钙钛矿太阳能模块的 Bilithic 集成”。该项目致力于开发一种全新的薄膜光伏（PV）模块制造方法，以此简化制造流程。这种创新方法在模组的 “Bilithic” 集成环节充分利用钙钛矿的特性，与单片集成方式不同，它能够对模组的顶部和底部进行独立处理，之后再将二者夹合在一起。这一方法为钙钛矿层的排列开辟了新的途径，有助于实现更出色的整体光伏性能，同时让制造过程更加轻松便捷。
迈阿密大学（University of Miami）也获得了一个 250,000 美元的项目，名为 “通过原子层沉积为钙钛矿太阳能电池和微型模组提供无机电荷传输层”。该项目旨在运用一种新方法改进钙钛矿电池，这种方法可以精确地控制材料成分和厚度，从而缓解钙钛矿的稳定性问题。在项目结束之际，该团队将把这一方法应用于电池和微型模组，以此展现其与光伏行业的紧密相关性。
Georgia Tech Research Corp. received $250,000 for a project titled: Low-cost Metrology Advancement for Perovskite Defect Quantification due to Environmental Stressors. This project aims to develop an instrument to test for defects in perovskite thin films by degrading perovskite devices and analyzing them. If successful, the instrument could be integrated into high-performance manufacturing lines and testing protocols, resulting in more accurate, reliable, and accelerated stability protocols for metal halide-perovskite photovoltaics (PV), increasing PV system lifetimes.
National Renewable Energy Laboratory (NREL) received $250,000 for a project titled: Visualizing Local Electric Fields with 4D STEM: Accessing the Missing Link for PV Device Optimization. This project aims to use scanning transmission electron microscopy (STEM) to demonstrate how perovskite interfaces change when operated under light, and how new materials can improve performance in cadmium telluride. The primary objective of this project is to develop an advanced STEM technique that can be routinely applied within the photovoltaics (PV) research community and enable advancements in thin-film PV material cell efficiency and durability.
Purdue University received $250,000 for a project titled: ITO-Free and Rollable Perovskite Solar Cells. This project seeks to introduce an innovative material for an electrically conductive transparent front layer of a perovskite module which would be easier to manufacture than the currently used indium tin oxide (ITO). This transparent conductive layer could be used to create flexible, high-efficiency, and cost-effective perovskite solar modules. Through this strategy, a fully rollable perovskite solar cell—with a bending radius smaller than one millimeter and a power conversion efficiency of over 18%—will be demonstrated. This project could enable a shift from costly, inflexible ITO module front layers to those that are flexible, cheap, and easily processed for perovskite photovoltaics and deliver on the promise of low cost solar.
University of California San Diego received $250,000 for a project titled: Bilithic Integration of Perovskite Solar Modules. This project seeks to develop a new approach to thin-film photovoltaic (PV) module fabrication to streamline manufacturing. This approach leverages the properties of perovskites in a “bilithic” integration of the module, which in contrast to a monolithic integration, allows independent processing of the top and bottom of the module and then sandwiching the two sides together. This approach enables new possibilities for how perovskite layers are arranged for better overall PV performance and easier manufacturing.
University of Miami received $250,000 for a project titled: Inorganic Charge Transport Layers via Atomic Layer Deposition for Perovskite Solar Cells and Minimodules. This project seeks to improve perovskite cells by using a novel approach which offers precise control over material composition and thickness to mitigate issues with perovskite stability. By the end of the project, the team will apply this approach to both cells and minimodules to demonstrate relevance to the photovoltaics industry.
