High-efficiency Thin-film Fe2SiS4 and Fe2GeS4-based Solar Cells Prepared from Low-Cost Solution Precursors. Final Report
The project aimed to provide solar energy education to students from underrepresented groups and to develop a novel, nano-scale approach, in utilizing Fe2SiS4 and Fe2GeS4 materials as precursors to the absorber layer in photovoltaic thin-film devices. The objectives of the project were as follows: 1. Develop and implement one solar-related course at Delaware State University and train two graduate students in solar research. 2. Fabricate and characterize high-efficiency (larger than 7%) Fe2SiS4 and Fe2GeS4-based solar devices. The project has been successful in both the educational components, implementing the solar course at DSU as well as in developing multiple routes to prepare the Fe2GeS4 with high purity and in large quantities. The project did not meet the efficiency objective, however, a functional solar device was demonstrated.
