The Scientific Division Renewable Energy, Institute Silicon Photovoltaics, is looking for a PhD Student (f/m), M.Sc./Dipl.-Ing. in Electrical Engineering or M.Sc./Diplom in Physics, Materials Sciences or Renewable Energies

The appointment is limited to 3 years.
The salary is based on the German Collective Agreement of the Public Service (TVöD).

Topic of the doctoral thesis:
“Development of device designs for silicon high efficiency rear contact solar cells”

Responsibilities:

• Design, fabrication and characterization of rear contact heterojunction (RCC-HET) solar cell architectures with structured a-Si and contact layers on silicon wafers and polycrystalline silicon on glass
• 1D-3D modeling of these cells using the available software packages such as HZB’s numerical simulation tool AFORS-HE and the commercial Sentaurus TCAD package
• Optimization of the cell designs based on these simulations
• Experimental realization of optimized device designs
• Obtaining a realistic estimate based on calibrated simulations of ultimate efficiency limits in the cells and understanding the physical reasons for these limitations

Informal inquiries: Dr. Lars Korte, phone: 030/8062-41351

Application deadline: February 9, 2015

As HZB endeavors to increase the number of women working in the scientific field, women are especially encouraged to apply.

Applicants with severe disabilities will be given preference to others of equal qualification.

Applicants should send their application, quoting reference number EE 2015/1, to Helmholtz-Zentrum Berlin für Materialien und Energie GmbH, Abteilung Personal und Soziales, Hahn-Meitner-Platz 1, 14109 Berlin via the "APPLY" button.

Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) operates two large scale research infrastructures, the neutron source BER II and the photon source BESSY II. These facilities serve an international user community from many scientific disciplines, hosting more than 3000 external users per year. HZB staff performs accelerator research, develops science-driven designs of new instruments and develops novel methods using synchrotron radiation in the VUV and soft-X-ray regime primarily for materials and energy research. Materials and energy research at HZB focuses on photovoltaics and solar fuel generation, as well as on fundamental aspects of energy storage and energy efficiency and new material systems for information technologies.
