Job Description

In this job scope we’re looking for a motivated candidate who could build technologies beyond limit of silicon based single-junction cell and look forward towards tandem cell & module development. 

  • Fabrication of >30% “industrially-viable” and “stable” large-area (>6”) high-efficiency tandem cell.
  • A team player towards integration of the ~30% cell to a commercially relevant module. 
  • Research focusing on the following:
    • Conceptualization, design, development and fabrication of low-cost methods for tandem solar cells & modules with a specific focus on commercialisation. 
    • Developing commercially relevant intellectual property (IP) portfolio in the above topic. 
    • Drive analysis and characterisation for complex industrial processes especially at an early stage of the commercialisation.   
    • Perform design-of-experiments (DOE) and advanced characterization to obtain optimised unit layers. 
    • Designing advanced patterning methods and/or masked/selective deposition. 
    • Effectively contribute in the project team(s) for solar cell & module efficiency improvements.
    • Assist in developing new processes and improving existing processes.
    • Regularly present loss (and gain) analysis of tandem cells 
    • Be involved in roadmap discussions and contribute to the design and development of new tools and processes 
  • Carry out processes for high-efficiency solar cells involving operation of tools such as: wet-chemical tools, tube furnaces, APCVD, PECVD(s), ALD, evaporation, sputter, versatile laser tool, metalisation tools and annealing furnaces.
  • Assist the research group with processing and characterisation services for various company-funded and public-funded projects.


  • PhD or Master’s Degree in Electrical Engineering or Materials Sciences with specialization in Silicon Photovoltaics or Microelectronics.
  • 3-5 years of experience in silicon wafer solar cell fabrication, thin-film solar cells, tandem cells and characterization, or other relevant experience.
  • Researchers with prior experience on development of tandem cells will be preferred.
  • Able to work in highly confidential projects. 
  • Required to work in semiconductor clean room and characterisation lab.
  • Expertise in relevant software for: DOE, data analysis, AutoCAD, grid design, layer/solar cell modelling. 
  • Excellent written and verbal communication (in English) skills required. 
  • Excellent customer service skills required.
  • Must be target/KPI-driven and well organized
  • Regular, reliable and predictable attendance and reporting required. 
  • Must be able to independently plan, initiate/execute and report on research activities. Project management experience is a plus, including managing a team of process and equipment engineers supporting the R&D activities 
  • Must be able to work well with others in a collaborative team environment.
  • Effective communication of ideas and results to the team and/or other stakeholders is crucial
