Project Summary: This master’s thesis investigates the mechanical reliability of perovskite–silicon tandem solar cells
under vibration loads representative of aerospace and satellite launches (e.g., Falcon 9 profiles). The goal is to reveal
vibration-induced failure mechanisms and develop more robust device and packaging designs for Low Earth Orbit
(LEO) applications.

Project Description:
You will develop and test encapsulation strategies, perform vibration experiments using an electrodynamic shaker,
and characterize device performance before and after testing. Mechanical weak points will be identified through
adhesion/delamination tests and advanced diagnostics such as laser vibrometry and high-speed imaging. Measured
material properties will be used to build finite element (FE) models, and ANSYS simulations will help analyze stress,
delamination origins, and critical failure points.

Key Responsibilities
• Develop and evaluate encapsulation and packaging strategies
• Perform vibration tests with a computer-controlled shaker
• Characterize device performance (IV, EQE) pre- and post-vibration
• Conduct adhesion and delamination tests
• Use laser vibrometry & high-speed imaging to capture mechanical response
• Measure mechanical properties of key materials
• Build FE models and run ANSYS simulations
• Compare experiments with simulation results

Outcome & Impact:
This project will identify dominant vibration-induced failure pathways in tandem solar cells and guide the design of
mechanically robust devices for future satellite and space-PV systems.
