Research Initiation Award: Novel Perovskite Solar Cells Based on Interface Manipulation

研究启动奖为历史上黑人学院和大学的初级和中级职业教师提供支持，他们正在建立新的研究项目或重新定向和重建现有的研究项目。预计该奖项将有助于进一步提高教师的研究能力和效率，改善家庭机构的研究和教学，并使本科生参与研究经验。授予杰克逊州立大学的奖项在许多领域都有潜在的更广泛的影响。该项目的目标是通过添加三元半导体层来研究钙钛矿太阳能电池的稳定性和效率;以及加强大学本科阶段的教学和学习。这项工作的重点是通过界面操作提高钙钛矿太阳能电池（PSC）的稳定性和效率。具有疏水性基团和可控能级的三元半导体层将用作PSC中的界面层，目的是获得高稳定性和高效率。目标是：1）发展三元半导体层的合成方法，通过三种元素的比例控制三元半导体层的能级，减少器件中的电荷复合; 2）用疏水基团钝化三元半导体层，防止水分渗透器件，提高器件的水分稳定性; 3）设计和发展新型的具有界面层的PSC器件结构;以及4）使用三元半导体层优化PSC器件性能以实现高稳定性和高效率。本研究有望解决PSC的稳定性问题，促进PSC向实际应用方向发展。该项目将与南密西西比大学和埃默里大学合作进行。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Research Initiation Awards provide support for junior and mid-career faculty at Historically Black Colleges and Universities who are building new research programs or redirecting and rebuilding existing research programs. It is expected that the award helps to further the faculty member's research capability and effectiveness, improves research and teaching at the home institution, and involves undergraduate students in research experiences. The award to Jackson State University has potential broader impacts in a number of areas. The goal of this project is to study the stability and efficiency of perovskite solar cells by adding a ternary semiconductor layer; as well as to enhance teaching and learning at the university at the undergraduate level. This work focuses on improving the stability and efficiency of perovskite solar cells (PSCs) by interface manipulation. Ternary semiconductor layers with hydrophobic groups and controllable energy levels will be used as interface layers in PSCs with the aim of obtaining high stability and high efficiency. The goals are to: 1) develop the synthesis methods for ternary semiconductor layers with adjustable energy levels controlled by the three element ratios, which can decrease the charge recombination in the devices; 2) passivate the ternary semiconductor layers with hydrophobic groups to prevent moisture penetrating the devices, which can improve the moisture stability; 3) design and develop novel PSC device structures with the interface layers; and 4) optimize PSCs device performance using the ternary semiconductor layers towards high stability and high efficiency. This study has the potential to solve the stability issue of PSCs and facilitate the development of PSCs toward practical applications. This project will be conducted in collaboration with the University of Southern Mississippi and Emory University.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.
