If you are excited about understanding complex system interactions and solving challenging performance issues, we would love to hear from you.

Your Role: Driving Integration and Deep-Dive Analysis

As a key member of our dynamic and international R&D team, you will play a crucial role in advancing our perovskite-silicon tandem solar cell technology by understanding and optimizing process interactions, material interfaces, and device performance.

Your Key Responsibilities:

• Analyse and develop a deep understanding of interactions between process steps and functional layers, including perovskite-based absorber stacks, in tandem solar cells
• Evaluate the impact of process variations on device performance, yield, and reliability
• Identify and implement integrated optimization strategies across the full process chain

Failure Analysis & Root Cause Identification:

• Perform deep-dive failure analyses when efficiency, stability, or yield targets are not met
• Combine and interpret process data, inline monitoring results, and imaging techniques such as PL/EL
• Identify root causes and systematically build failure catalogues and knowledge databases

Data-Driven Problem Solving:

• Apply statistical methods to correlate process parameters with device performance
• Design and execute experiments to validate hypotheses and eliminate failure modes
• Collaborate closely with material, process, and production teams
• Translate analytical insights into process and technology improvements
• Support global production sites in implementing solutions
• Contribute to the continuous improvement of manufacturing robustness

Technology Leadership:

• Drive innovative approaches to enhance efficiency, yield, and long-term reliability
• Actively contribute to technology roadmaps and future concepts

Your Profile: Expertise Meets Analytical Mindset

We are looking for a highly motivated scientist or engineer with a strong analytical mindset and a passion for understanding complex systems.

Your Qualifications:

• Degree in science or engineering (PhD preferred)
• Experience in photovoltaics, semiconductor technology, or related high-tech industries
• Strong understanding of process integration and/or failure analysis
• Experience with data analysis, statistics, and ideally Design of Experiments (DoE)
• Knowledge of imaging techniques such as PL/EL is a plus
• Experience with perovskite solar cells or perovskite-silicon tandem technologies is highly desirable (not mandatory)
• Structured, analytical, and solution-oriented working style
• Ability to interpret complex datasets and communicate findings clearly
• Strong teamwork and communication skills in an international environment
• Very good written and spoken English (German is a plus)
• Willingness to travel internationally

Why Qcells?
