Intro

At NexWafe, we are developing a pioneering process to produce silicon wafers for PV applications with fewer process steps, leading to significant reductions in production costs, energy consumption, and CO₂ emissions.
As a Process Development Engineer (m/f/d), you will have a unique opportunity to actively contribute to the commercialization of this breakthrough technology by shaping a product strategy based on market trends, customer input, and internal goals. You will define and refine a technical and cost roadmap, exploring future applications such as LEO, HJT, Tandem, and TOPCon.
Join our global team, help shape the future of renewable energy, and explore exciting career opportunities at NexWafe!

Your Mission

• Performance analysis of epitaxially grown Epi wafers in Tandem/HJT/TOPcon assembly in terms of efficiency, Voc, Isc, FF, etc. compared to Cz-grown Si wafers
• Analyze and differentiate various failure modes of Si wafers in Soler cell configurations and trace back to the root cause related to material properties of epitaxially grown monocrystalline silicon
• Analyze and improve material defects in epitaxially grown monocrystalline silicon wafers which leads to higher cell efficiencies
• Along with colleagues, determine improvements in other process steps besides epitaxial deposition to improve material properties and cell efficiencies
• Design experiments in epitaxial deposition to engineer material properties that could be enhancements compared to Cz-grown Si wafers in the manufacture of solar cells of various architectures

Your profile

• Degree (Master preferred) in Engineering or Science, e.g. Physics, Chemistry, Materials Science
• Experience in solar cell manufacturing
• Minimum 5 years experience in relevant field (solar cell analysis)
• Experience in silicon-based solar cell/Module Failure Analysis  
• Fluent in English
