Internship | Optimisation of processing settings for encapsulants in flexible solar applications

What will you be doing?

As the energy consumption is still rising the transition to more renewable energy is becoming increasingly important. PV is a promising renewable energy generation.

To answer to the demand of renewable energy PV also needs to be implemented in more innovative ways, using surfaces not competing with agricultural areas and already available surfaces on buildings. State of the art flexible modules are still too expensive for large scale application. Due to their standard size and electrical architecture they don’t allow adaptation to specific applications.

The Integration Team of Solliance works on the development of flexible PV foils that can be used in mass-production and in any application. The final goal is to have freedom in size, shape, electrical output and lifetime for competitive costs. An important challenge for this goal is to find the suitable materials and processing of the solar cell material that allow sufficient protection, low cost and flexibility.

By testing the effect of using different materials, architectures and processes on the lifetime of a flexible solar cell, we try to reach optimal configurations. During this internship project you will study the influence of processing parameters and encapsulant choice on the final properties of the encapsulant material. For this purpose you will make prototypes using both material coupons and functional devices, and analyze their optical and mechanical properties and electrical performance after processing and different accelerated lifetime tests. This knowledge is required for the ongoing optimization towards a flexible PV foil that can be used for integration of PV foil in mass-produced products.

What do we require from you?

Independent working attitude, with hands on approach. Good communication skills to discuss/present results to colleagues and find explanations for the observed effects. Initiative to set out own further experiments and decent planning.

What can you expect of your work situation

TNO is an independent research organisation whose expertise and research make an important contribution to the competitiveness of companies and organisations, to the economy and to the quality of society as a whole. Innovation with purpose is what TNO stands for. With 3000 people we develop knowledge not for its own sake but for practical application. To create new products that make life more pleasant and valuable and help companies innovate. To find creative answers to the questions posed by society. We work for a variety of customers: governments, companies, service providers and non-governmental organisations. Working together on new knowledge, better products and clear recommendations for policy and processes. In everything we do, impact is the key. Our product and process innovations and recommendations are only worth something if our customers can use them to boost their competitiveness.

Much of the work will take place in the lab, but of course you will also need to take time in the office to process and analyze measurement results, and discuss them with your colleagues. You work in a team of about 20 people, of which about 5 are interns with topics in the same group.

What can we offer you?

You want to work on the precursor of your career; a work placement gives you an opportunity to take a good look at your prospective future employer. TNO goes a step further. It’s not just looking that interests us; you and your knowledge are essential to our innovation. That’s why we attach a great deal of value to your personal and professional development. You will, of course, be properly supervised during your work placement and be given the scope for you to get the best out of yourself. Naturally, we provide suitable work placement compensation.
