PhD scholarships in Photovoltaic Systems Research – DTU Electro
Roskilde, Denmark
Job Description

The Solar Photovoltaic Systems group at DTU Electro (Risø campus) is at the forefront of advancing research within a broad spectrum of applied photovoltaics (PV), encompassing building-integrated photovoltaics (BIPV), potential induced degradation (PID) in high-voltage PV modules, and the challenges of spatial and temporal irradiance variability on large PV plants. 
Our team is dedicated to pioneering solutions that enhance the efficiency, reliability, and integration of PV systems in urban and utility-scale environments. Collaborating with industry leaders, other academic institutions, and utilizing state-of-the-art experimental setups, we are investigating innovative materials, technologies, and methodologies to address current challenges in the field. 
Our work extends from developing structural coloured foils for BIPV products, mitigating PID effects in next-generation PV modules, to modelling the impact of environmental factors on PV performance. 
Through our comprehensive research endeavours, we aim to contribute significantly to the global transition towards sustainable energy.
Responsibilities and qualifications
Position 1:
This position is embedded in a larger project developing structural colored foils for BIPV products together with industry partners and other leading universities. The specific tasks include the establishment and operation of accelerated stress tests of coupon-sized colored PV modules, i.e. UV degradation and thermocycling, as well as pre- and post-test characterization and material analysis.  The tasks will include:

• Investigate polymeric material compatibility of structural colored foils within the PV laminate
• Establish a test stand for accelerated UV degradation of coupon-sized PV modules
• Conduct accelerated stress testing according to relevant standards (mostly IEC 61215)
• Contribute with measurement results to the product development of structural colored foils

Position 2: 
PhD candidate sought for research on potential induced degradation (PID) in high-voltage PV modules, part of a strategic initiative with TotalEnergies to enhance PV module reliability. This role focuses on the evaluation and mitigation of PID effects in new and existing solar cell technologies under varied environmental conditions. Key tasks include:

• Assessing PID sensitivity and recovery kinetics in high-power, high-voltage PV modules against different materials and increased soiling rates.
• Establishing a high voltage field stress setup as per IEC 62804-2-2022 for in-situ degradation monitoring, aimed at quantifying PID sensitivity and recovery under realistic environmental conditions.
• Determining acceleration factors and developing models for PID degradation and recovery, to accurately predict module performance in utility-scale PV environments.
• Evaluating the efficacy of PID prevention and recovery solutions from various manufacturers, integrated into inverters or as standalone units.

The successful candidate will contribute to setting industry benchmarks for PID resistance and recovery, ensuring the longevity and efficiency of next-generation PV installations.
Position 3:
PhD candidate needed for a pioneering study on the effects of spatial and temporal irradiance variability on PV plant performance. This research aims to enhance monitoring and stability of large PV installations under dynamic weather conditions. Responsibilities include:

• Quantifying and modeling the impact of spatial and temporal irradiance fluctuations on PV string and plant output, particularly for plants with fixed tilt and horizontal axis trackers (HSAT).
• Deploying and integrating fast sensors at pilot and R&D sites including bifacial, high-performance, and floating PV plants to collect high-resolution irradiance and power output data.
• Developing and validating models to estimate the spatial irradiance averaging effect and the temporal fluctuation averaging effect, improving the predictability and reliability of PV plant performance.

The role involves hands-on experimental setup, data analysis, and model development, contributing crucial insights for optimizing PV plant design and grid integration strategies.
