Large scale application of solar cells relies on simple, low cost (yet efficient and flexible) processing as well as the use of earth-abundant and non-toxic materials. Iron pyrite (FeS2) and antimony selenide (Sb2Se3) are earth-abundant materials that are attractive for solar cell applications due to large absorption cross sections, simple phase chemistry, and defect tolerant grain structure, respectively. However, challenges remain in performance due to polycrystallinity of the films and limiting surface defects.This experimental project will investigate how laser processing can be used to process thin films of FeS2 and Sb2Se3 colloidal nanocrystals into solar cell absorber layers and how initial materials and laser processing parameters affect the interaction with the material and the final device functional performance.

太阳能电池的大规模应用依赖于简单、低成本(但高效和灵活)的加工以及地球资源丰富和无毒材料的使用。黄铁矿(FeS_2)和Sb_2Se_3(Sb_2Se_3)分别以其较大的吸收截面、简单的相化学和允许缺陷的颗粒结构而成为太阳能电池中的富稀土材料。然而，由于薄膜的多晶性和有限的表面缺陷，在性能方面仍然存在挑战。本实验项目将研究如何使用激光处理将FeS2和Sb2Se3胶体纳米晶薄膜加工成太阳能电池吸收层，以及初始材料和激光加工参数如何影响与材料的相互作用和最终的器件功能性能。
