Novel passivated polysilicon contacts using printable dopants (PhD project)

People

Collaborators

Crystalline silicon (c-Si) solar cells have a market share of < 90% and represent the most mature and promising photovoltaic technology to replace fossil fuels and nuclear energy sources. In industrial solar cells, the direct metal/silicon interface leads to high recombination losses. This limitation can be overcome by so-called polySi passivating contacts which separate the metal from the wafer while simultaneously passivate the wafer surface. These passivating contacts have led to several world-record devices over the last few years and are currently being implemented in industrial R&D lines. In collaboration with world-leading manufacturers, this project will develop alternative doping methods for this polySi passivating contacts using printable liquids and laser processes . Thanks to our state-of-the-art laboratories and advanced fabrication and characterisation facilities, this project is researching at the cutting edge of high-efficiency silicon solar cells.

This project will be largely experimental, with numerical and analytical modelling to support the findings. The project will be supervised by Prof. Daniel Macdonald and Dr. Josua Stuckelberger.

Key Task & Responsibilities:

  • Conduct research on the development of novel passivated polysilicon contacts, experimental work and associated theoretical analysis in relation to crystalline silicon solar cells
  • Contribute to the writing of scientific papers and reports
  • Participation in international conferences and/or workshops relevant to the projec

Requirement:

  • Outstanding degree in electrical engineering, physics or a related field of study
  • Independent, structured working method, and ability to think analytically
  • High level communication skills, strong interpersonal skills and ability to work with peers and superiors
  • Knowledge of photovoltaics or solid-state physics is helpful
