If you are driven by innovation and want to work at the forefront of laser-based manufacturing processes, this is your opportunity to make a global impact.

Your Role: Advancing Laser Processes for Tandem Solar Cells

As a key member of our dynamic and international R&D team, you will take ownership of laser-based processes in perovskite development. You will play a critical role in developing, optimizing, and scaling laser technologies to enable high-efficiency tandem solar cells.

Your Key Responsibilities

• Laser Process Development:
  Develop, optimize, and implement laser processes for perovskite tandem solar cells, including cell separation (scribing/dicing) and edge isolation.
• Technology Ownership:
  Take full responsibility for all laser-related process steps across the perovskite device flow, ensuring performance, stability, and scalability.
• Process Integration:
  Collaborate closely with coating, materials, and device teams to integrate laser steps seamlessly into the overall cell architecture and process flow.
• Experimental Excellence:
  Plan and execute experiments, analyze data, and continuously improve processes, equipment, and device performance.
• Technology Transfer:
  Support the transfer of laser processes from R&D to pilot lines and production environments, ensuring robustness and reproducibility.
• Equipment & Supplier Management:
  Work with equipment manufacturers and internal stakeholders to define specifications, qualify tools, and drive technological advancements.

Your Qualifications

• Degree in Physics, Engineering, Materials Science, or a related field.
• Strong experience in laser-material processing, ideally in photovoltaics, semiconductors, or thin-film technologies.
• Hands-on expertise in processes such as laser scribing, ablation, structuring, dicing, or edge isolation.
• Knowledge of perovskite or tandem solar cell technology is a strong advantage.
• Structured, analytical, and solution-oriented working style.
• Strong communication skills and ability to work in interdisciplinary teams.
• Experience with data analysis and statistical tools.
• Fluency in English.
• Willingness to travel internationally.
