Improving long-term performance of adhesives on solar panels
We have an opening in a two-year post-doctoral project to study the long-term behaviour of adhesives of solar panels when subjected to an outside environment. The adhesives are used in small panel constructions and encounter harsh environmental conditions such as water, temperature, and UV light fluctuations. This may lead to detoriation and/or delamination of the adhesive bond, at worst leading to failure of the construction. The aim of this research project is to optimise the adhesive bond by improving the adhesion to the polymer solar panel frame, and to understand which physical phenomena are relevant for the overall degradation in order to predict a lifetime for the adhesive bond of 20 years. This may help the industry to develop panels with a long-term life expectancy. The research comprises literature research, physical surface treatments and mechanical/physical testing. The accelerated aging will take place in climate rooms. The physical phenomena have to be modelled theoretically, and the results will be verified experimentally in the DASML lab of the TU Delft.
We are looking for an enthusiastic and creative researcher motivated to push the limits of durability in adhesive bonds. Applicants should have the following qualifications:
• PhD in material engineering, mechanical engineering, aerospace engineering, applied physics, or another relevant discipline.
• Extensive experience with material testing, polymer science, analysis, and modelling.
• Knowledge of modelling degradation mechanisms in polymer materials.
• Excellent English, communication, and reporting skills.
• Comfort working both independently and in a team.
• A pro-active, independent, problem-solving, and result-oriented work attitude.
Applicants will be expected to publish and participate in international conferences.
