We are now looking for

A Postdoctoral Researcher and a Doctoral Student to conduct research on Energy- and cost-efficient production of solar energy under arctic environmental conditions

Description of the positions

The Postdoctoral Researcher is responsible for conducting the design and constructing of instrumentation and performing the measurements to predict the solar energy harvesting efficiency of photovoltaic installations in unconventional artic conditions. In addition, tasks related to simulation model development and experimental data analysis needed for optimization the efficiency of solar harvesting installations is needed.

The Doctoral Student is expected to improve the understanding of the impact of arctic environmental conditions, in particular that of snow and ice, on the operation and power output of solar panels. The specific subject areas of this position are:

Optimizing the operation of solar photovoltaics in winter conditions
Determining the polarization factor caused by the reflection from snow and ice
Consolidation of measured data with solar PV system modelling
Systems level forecasting of the role of photovoltaics in energy transition in the Arctic
The work will include simulations and empirical observations, and the candidate will be responsible for the design and development of methods for measuring the interrelation between snow and ice coverage on the solar production in an Arctic environment. The work will further include developing models based on these measurements to improve the inclusion of Arctic conditions in PV-system models. These models will be further used to improve short- and long-term forecasting of PV-system output. We are looking for a Doctoral Student with a strong knowledge of energy systems and energy technologies to conduct this research and complete their degree of Doctor of Technology. This includes post-graduate studies, independent research and writing a minimum of 3 scientific articles and publishing them in high impact peer-review journals. The selected applicant will work in a team of environmental engineers focusing on smart grid and energy transition research. The research will be conducted in Oulu, Finland, and the researcher will have access to the research facility and PV installations at the University of Oulu, Linnanmaa campus.

Description of the research groups

The Postdoctoral Researcher position is placed at the Optoelectronics and Measurement Techniques Research Unit (OPEM), Faculty of Information Technology and Electrical Engineering. OPEM holds an established position as an internationally recognized research organization in the field of optical measurement technologies and additive manufacturing of optics and electronics. In the latest international research assessment at the University of Oulu, OPEM’s scientific research was evaluated to the highest level. The education and research activities cover the topics such as optoelectronics based instrumentation and measurement and printed electronics fabrication and characterization. OPEM is multidisciplinary research group which is actively collaborating with the best international research groups around the world including the large number of industrial partners. The majority of OPEM’s research is externally funded by the Academy of Finland, EU, and Business Finland (former Tekes). The research unit is the vibrant and inspiring multicultural team of young and motivated people with an access to modern and diverse research facilities and instruments.

The Doctoral Student position is placed at the Water, Energy, and Environmental Engineering (WE3) in its research group focusing on energy technology ( at the Faculty of Technology. The Energy and Environmental Engineering (EEE) Group focuses on research and education in smart and sustainable energy systems and circular economy. Our expertise is in smart grids, critical materials, material flow analysis and sustainability assessment. A special focus of EEE is on Northern and Arctic aspects of energy technologies and resources management. The research of EEE falls under the University of Oulu's strategic research area of "Creating sustainability with materials and systems". Our research also supports the social sustainability dimension of technologies, sustainable regional development, and the energy transition process. We have substantial experience in international projects and EU funding, supported by a wide cooperation network in Europe. We are conducting several basic, applied and advanced projects in energy technologies and circular economy. We are also providing education and guidance to the students of the sustainable energy systems orientation at the Faculty of Technology.
