Masterarbeit - Laserprozessoptimierung für die Realisierung einer plastikfreien Verkapselungsmethode

Master Thesis - Laser process optimization for the realization of a plastic-free encapsulation method

At Institute of Energy Materials and Devices - Photovoltaics (IMD-3), among other research topics we are working on innovative module concepts for the future of photovoltaic modules. These module concepts need to fit the requirements of a circular economy, where the recycling at the end of life of a photovoltaic module is essential (D4R, Design for Recycling). As part of this master’s thesis, a laser process will be optimized to contribute to the development of a “plastic-free” encapsulation method. In this process, glass and metal are welded together using a fs-laser. The goal is to encapsulate a single Si wafer respectively a single Si solar cell between two glass substrates using this welding process. The quality of the encapsulation in terms of moisture ingress prevention will be assessed through Damp-Heat tests and qualitative lifetime measurements.

Your Job:

• Literature research on /Familiarization with the topic of laser welding of glass and metal
• Familiarization with the laser system
• Qualitative measurement of the lifetime of charge carriers in processed Si wafers/solar cells
• Optimization of the laser process for joining glass with metal
• Glass-to-glass encapsulation of a wafer/solar cell using the glass-metal joining process
• Verification of the encapsulation quality using Damp-Heat tests (moisture ingress) and lifetime measurements
• Analysis and documentation of the results

Your Profile:

• Excellent academic performance in a master’s program in electrical engineering, materials science, mechanical engineering, physics, or a related field
• Basic knowledge of laser technology
• Initial experience in optimizing laser processes and with an object-oriented programming language (e.g., Python, Matlab) is beneficial
• Analytical and structured thinking
• Fluent written and spoken English or German
