lavori da Naturwissenschaftler in località Germania

At Helmholtz-Zentrum Berlin, we research materials and processes for next-generation solar cells. To this end, we are developing technologies with the highest stable efficiency combined with cost-effective and resource-efficient production. One of the most promising candidates are monolithic perovskite/silicon tandem solar cells. With such a tandem cell, we have already achieved world record efficiency of over 30% in the laboratory. At the same time, we are developing scalable processes to produce industry-relevant tandem solar cells and modules with high efficiency and long-term stability, partly with industry participation.

In the project DaTA, data for technology assessment, we collect information to enable researchers to assess the sustainability of future energy system integration. For the purpose of being a first user of the data bank under development and for intensifying our research on life cycle assessments (LCAs) and techno-economic assessments, we are looking for a doctoral student. You will be co-supervised by TU Munich and can look forward to enganging challenges in a rapidly evolving field, working in a state-of-the-art facility as part of a highly motivated team.Your position is embedded in theInnoPool project DaTA, in which you will collaborate with research groups of several Helmholtz centres.

• Based on a techno-economic data base of PV technologies you develop methods for semi-automated generation of Life Cycle Inventory data, e.g. with machine learning.
• You develop test cases for validating the semi-automated generated data.
• You develop methods and tools for the validation of the models.
• The PhD thesis builds on an existing student work on techno-economic assessment of AgriPV. You systematically review the existing state-of-the art, develop research questions and conduct deep studies in consultation with your supervisors and collaborators.
• You evaluate others and your own studies and present results in project meetings.
• You publish results in oral and written form at conferences and in international peer-reviewed scientific journals.

• Master's degree in information systems, chemistry, physics, engineering, computer science, mathematics or a similar field
• Experience in (multi-) energy systems or LCA/TEA studies
• Experience with programming, preferably in Python
• High level of intercultural competence and ability to work as part of a team

• Opportunity to contribute to the development of innovative materials and technological solutions for a climate-neutral future in cooperation with leading international researchers
• Commitment to diversity and sustainability through an inclusive working environment, promotion of diversity sensitivity and implementation of sustainable and climate-neutral methods
• Career-enhancing networking opportunities and individual mentoring and support from the HZB Graduate Centre and HZB Postdoc Office
• Attractive remuneration through payment according to Public Service Wage Agreement (TVöD Bund)
• 30 days holiday/year
• Extensive additional benefits, such as company pension plan (VBL), subsidy for public transport (Deutschlandticket Job) and company sports programmes
• Good work-life balance through counselling services on family and career and flexible working time models: Flexitime, part-time, hybrid working
• And a team that is looking forward to meeting you!

Fixed term contract for 48 months.The salary is based on the Collective Agreement for the German Public Service (TVöD-Bund).We look forward to receiving your application via our application management system by 20.07.2025. For reasons of data protection regulations,we are unfortunately unable to consider applications that reach us by any other means (such as email or mail) in the application process.
