Project Description

The goal of this project is to design an experimental setup to support X-ray characterization experiments for metal halide perovskite (MHP) precursor solutions. (e.g., small angle X-ray scattering (SAXS), X-ray absorption spectroscopy (XAS)).

Fabrication of solution-processed perovskite solar cells (PSCs) involves the rapid nucleation and crystallization of MHP thin films. Limited control over MHP precursor solution chemistry makes it difficult to reproducibly fabricate stable and efficient solar cells. The selected student will contribute to the design-of-experiments for research on MHP solution chemistry. 

Learning Outcomes

  1. Learn to prepare MHP precursor solutions and understand the fabrication of solution-processed thin films.
  2. Become familiar with synchrotron-based X-ray characterization techniques and their applicability to MHP precursor solutions and thin films.
  3. Design an experimental setup to actively flow MHP precursor solutions for measurement by XAS and SAXS techniques.
  4. Learn to acquire powder X-ray diffraction (XRD) data, and perform measurements on MHP precursor solvate complexes.
