Project description

In agrivoltaics, land is co-utilized for crop growth and electricity production using solar cells. In this context, it is desirable to share the sunlight between the crop and solar cells such that the highest possible value is generated overall. With this in mind, the project aims to develop and investigate new concepts within agrivoltaics, where the interaction between light, solar cells and cultivated crops is controlled using nanostructured layers adjacent to the solar cells. The challenges and research questions lie within theoretical development, understanding and evaluation of new optical structures, experimental fabrication of desired structures, possibilities to scale up the technology, and experimental studies and evaluation of promising concepts in model and pilot systems of relevance for agrivoltaic systems at different scales.

For scaling up and possible commercialization of the technology, the project will be carried out in close collaboration with Mycronic AB, a global leader in the development and manufacture of high-precision equipment for photolithography, which is mainly used in the semiconductor and display industries. Mycronic's expertise in high-resolution patterning offers exciting opportunities to test structures on a larger scale and to transfer concepts into practical application within the next generation of solar cell technology.

Duties

The main duty for a doctoral student is to devote themselves to their doctoral studies which includes participating in research projects and PhD courses. The work duties can also include teaching and other departmental duties (no more than 20%).

Being a PhD student means independently running projects within a specific doctoral research subject. You collaborate on an ongoing basis with other doctoral students and researchers to create results within various projects and have one or more supervisors for support during your doctoral studies. However, you work independently to a large extent, e.g. by working in a laboratory environment and writing articles for scientific journals and contributing to your doctoral thesis. Usually some form of half-time seminar is included after about half of the doctoral studies.

When you are admitted to doctoral studies, you are offered employment as a doctoral student. A position as a doctoral student at Uppsala University corresponds to full-time PhD education for four years.

In the project, you will use theoretical models to develop and evaluate optical structures, and to analyze and understand optical measurements. A large part of your time will be devoted to experimental development of lithographic techniques for producing desired nanostructures, to various characterization methods for determining structural and optical properties, and to measurements of performance in relation to the agrivoltaics application.

Typical work tasks include:

Experimental process development in a cleanroom environment
Experimental measurements and analysis
Computer-based modelling of nano-optics
Summarizing and interpreting results Scientific writing (in English)
Presentation in writing and speech (in English)
Working in an interdisciplinary team with expertise in solar cell technology, agrivoltaics and nanotechnology.

Eligibility requirements

To meet the general entry requirements for doctoral studies, the applicant must have completed a degree at second-cycle level, completed at least 240 credits of higher education studies, of which at least 60 credits are at second-cycle level including an independent project of at least 15 credits, or otherwise acquired substantially equivalent knowledge.

Rules governing PhD students are set out in the Higher Education Ordinance (1993:100) chapter 5, §§ 1-7 and in Uppsala University's rules and guidelines.

Requirements

A Master’s degree or a Master of Science in Engineering degree in physics, engineering physics, materials science, or a related field, or other education considered equivalent to these qualifications.

Documented knowledge in optics and electromagnetism
Documented knowledge and experience of experimental work
Good knowledge of programming in, for example, Matlab or Python.
Good oral and written proficiency in English.

Additional qualifications

It is advantageous to have documented knowledge and experience in one or more of the following areas:

Work in a cleanroom environment
Work with electron and photolithography, thin-film technology, optical characterization, and electron microscopy
Optical modeling and simulation
Solar cell physics and technology, sustainable energy and related technology

Great emphasis is put on personal qualities such as the ability to independently plan and carry out work. You switch effectively between practical work in the laboratory and theoretical analysis at the computer. You have a strong ability to work with focus toward set goals, while maintaining a mindset open to new information and discoveries. You proactively address difficulties, and you are resilient and not deterred by setbacks. You have good communication skills, and you cooperate well with others. You also have a good ability to write academic text.

Your application must include

A short cover letter in which you describe yourself, why you want to do a PhD and why you are suitable for this position.
CV (max 2 pages)
A certified copy of your master's degree and your course grades.
Copies (or drafts) of your master's thesis and other documents, such as publications, that you wish to refer to.
Names and contact details of at least two contact persons who have agreed to be references for you, with any additional letters of recommendation. It must also be stated what relationship you have had with the respective referent.

The application should be written in English. We will continuously read applications and call for interviews.
