Nontechnical:Solar cells convert light directly into electricity via the photovoltaic effect. Their ability to efficiently and economically harness solar energy makes them a promising source of power. Silicon has proved to be the best material for making solar cells. A new class of materials, hybrid perovskites made from organic and inorganic components, have been used as the light-harvesting active layer in solar cells. Perovskite solar cells have attracted great attention as their performance approaches that of silicon and they are compatible with low-cost processing and flexible electronics. So far, the most efficient state-of-the-art perovskite solar cells were observed from the lead-based hybrid perovskites. Tuning the optical and electronic properties of hybrid perovskites by replacing lead or tin with other metal ions is relatively unexplored. Studies have also shown that unbalanced charge carrier diffusion within perovskite thin films limits the performance of perovskite solar cells. This project will address above issues by developing perovskite solar cells with a bulk heterojunction (mixed) device structure made from novel hybrid perovskites. The success of this project is expected to significantly advance the field of perovskite solar cells. The project will also provide cutting edge research opportunities to undergraduate and graduate students.Technical:This project aims to develop efficient perovskite solar cells with a bulk heterojunction device structure by novel hybrid perovskite materials. The first objective is to develop novel hybrid perovskite materials, where lead (or tin) is substituted by different metal cations. The second objective is to investigate molecular and crystal structures, film morphologies, optoelectronic properties, and photovoltaic properties of these novel hybrid perovskite materials. The third objective is to investigate perovskite solar cells with a bulk heterojunction device structure by novel hybrid perovskite materials. The fourth objective is to correlate the device performance of bulk heterojunction perovskite solar cells with molecular and crystal structures, film morphologies and optoelectronic properties of bulk heterojunction composite photoactive layers. This project will advance the fundamental understanding about the interplay of molecular and crystal structures, the optoelectronic properties of novel hybrid perovskite materials, device physics and engineering, and the enhancement of device performance of perovskite solar cells. Insights gained from this work will elucidate materials design and device physics rules through comparison of device performance with materials properties. The participation of students in science, technology, engineering and mathematics disciplines will be increased by engaging high school and undergraduate students using inquiry-based methods and hands-on learning activities.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.

非技术性：太阳能电池通过光伏效应直接转化为电能。他们有效和经济利用太阳能的能力使它们成为有前途的力量来源。事实证明，硅是制造太阳能电池的最佳材料。一类新的材料，由有机和无机成分制成的杂化钙化物已被用作太阳能电池中的轻度收获活性层。当钙钛矿太阳能电池吸引了极大的关注，因为它们的性能接近硅的性能，并且与低成本加工和柔性电子兼容。到目前为止，从铅基杂种钙钛矿中观察到了最有效的钙钛矿太阳能电池。通过使用其他金属离子代替铅或锡来调整混合钙壶的光学和电子性能是相对尚未探索的。研究还表明，钙钛矿薄膜内不平衡的荷载体扩散限制了钙钛矿太阳能电池的性能。该项目将通过开发由新型杂种钙钛矿制成的大量异质结（混合）设备结构来解决上述问题。预计该项目的成功将显着推动钙钛矿太阳能电池的领域。该项目还将为本科和研究生提供尖端的研究机会。技术：该项目旨在通过新型的混合钙钛矿材料来开发具有散装异质结构结构的高效钙钛矿太阳能电池。第一个目标是开发新型的杂化钙钛矿材料，其中铅（或锡）被不同的金属阳离子取代。第二个目标是研究这些新型杂交钙钛矿材料的分子和晶体结构，膜形态，光电特性以及光伏特性。第三个目标是通过新型杂种钙钛矿材料研究钙钛矿太阳能电池，并用大量的异质结构结构进行研究。第四个目标是将散装异晶孔孔太阳能电池的装置性能与分子和晶体结构，膜形态和散装异质结合复合光活性层的光电特性相关联。该项目将提高人们对分子和晶体结构相互作用的基本了解，新型混合钙钛矿材料的光电特性，设备物理和工程以及钙钛矿太阳能电池的设备性能的增强。从这项工作中获得的见解将通过将设备性能与材料属性进行比较，从而阐明材料设计和设备物理规则。通过使用基于询问的方法和动手学习活动来吸引高中和本科生，学生参与科学，技术，工程和数学学科将增加。这项奖项反映了NSF的法定任务，并被认为值得通过基金会的知识分子优点和更广泛的影响来通过评估来获得支持。
