Title: High-efficiency Thin-film Fe 2SiS 4 and Fe 2GeS 4-based Solar Cells Prepared from Low-Cost Solution Precursors. Final Report

Abstract

The project aimed to provide solar energy education to students from underrepresented groups and to develop a novel, nano-scale approach, in utilizing Fe 2SiS 4 and Fe 2GeS 4 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%) Fe 2SiS 4 and Fe 2GeS 4-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 Fe 2GeS 4 with high purity and in large quantities. The project did not meet the efficiency objective, however, a functional solar device was demonstrated.
