Shining Light on Halide Perovskites: Teaching Analytical Chemistry Using Flexible, Inquiry-Based Experiments

Area of Science:

• Materials Science
• Analytical Chemistry
• Solid-state Chemistry

Background:

• Two-dimensional (2D) metal halide perovskites are advanced semiconducting materials with significant potential in next-generation solar cells and LEDs.
• Research in perovskite materials is rapidly expanding, necessitating effective pedagogical approaches for undergraduate education.

Purpose of the Study:

• To develop and evaluate an intermediate analytical chemistry laboratory module centered on the study of 2D metal halide perovskites.
• To integrate fundamental chemistry concepts (solubility, complexation, spectroscopy, microscopy) with contemporary materials research.

Main Methods:

• A modular, inquiry-based laboratory curriculum was designed for undergraduate students.
• Experiments covered synthesis, structural characterization, and property analysis of 2D perovskites.
• Student learning and engagement were assessed via surveys.

Main Results:

• Students successfully applied analytical chemistry techniques to study perovskite materials.
• The laboratory module facilitated a holistic understanding of perovskite synthesis, structure, and properties.
• Student surveys indicated high interest and significant learning gains.

Conclusions:

• This laboratory experience effectively bridges fundamental analytical chemistry principles with cutting-edge materials research.
• The curriculum is adaptable to various course, student, equipment, and budget constraints.
• It provides a valuable model for teaching contemporary scientific concepts in an undergraduate setting.
