Scholarship : PhD student in Computer and System Sciences

Mid Sweden University has in the Industrial IT and digital services, an extensive research in the field of ubiquitous media over networks as well as distributed sensor and user information. Research in the group for realistic 3D visualization is mainly focused on capturing, coding and quality evaluation of stereoscopic and multi-view 3D images and video. We are now looking for a graduate student that shall study algorithms for compression (encoding) of visual 3D video, and to some extent capture methods for such media. More information is available at www.miun.se/sr/3d.

Duties: As a PhD student, your main task is to pursue research and graduate studies. An interest in mathematical formulation and analysis, and programming is required. The work is of theoretical nature with elements of computer simulations and some experimental work. The work will also involve close cooperation with industrial partners and international contacts.

Jurisdiction: Qualified for application is student who before 1st of June 2007 has completed basic education of at least 120 credits and advanced courses of at least 60 credits, or alternatively, who after 1st of June 2007 have passed an examination at advanced level or have completed course requirements of at least 240 ECTS credits, including at least 60 credits at advanced level. In addition, the applicant shall have at least 90 ECTS credits in relevant research discipline or corresponding knowledge. Good knowledge of English, both orally and in writing, is a requirement. Master of Science degree in electrical engineering, computer science or engineering physics is an appropriate background for employment.

Selection: In addition to the formal qualifications, selection is also based on other works (e.g. thesis), and advanced level courses, and through interviews of applicants. Besides good subject knowledge, emphasis will be on creative thinking, co ability, initiative to work independently and personal suitability for research training. Previous experience of coding practices and / or 3D visualization is meritorious.

Employment: This PhD student post is primarily a 2,5-year employment and is expected to lead to a licentiate degree. Employment may be extended up to the doctorate, provided that additional financing is obtained. Location: Sundsvall.

Duties commencement: 1 January 2011, or by appointment.

Salary: According to Mid Sweden University regulations for graduate students.

Contact: Information concerning the employment is provided by Associate Professor Mårten Sjöström, e-mail marten.sjostrom [at] miun.se, phone +46-60-14 88 36.

Union representatives are Anders Nyström, SACO, phone +46-611-862 45, Lollo Ljuslin, ST, phone +46-63-16 57 14.

PhD scholarship in Nano-structure of Organic-based photovoltaic cells phd sociology

The exploitation of organic materials for converting sunlight into electricity is believed to convey several advantages such as light weight, flexibility, environmental friendliness, a low thermal budget, low cost and most notably very fast modes of production by printing techniques. Issues related to scaling to large area plastic solar cells are slowly starting to be resolved and production of very large modules up 1000 square centimetres have been reported. Some challenges remain to be addressed before organic solar cells can fulfil their potential as a pervasive, low-cost source of renewable energy, notably improving their efficiency and their long term stability.

The Solar Energy Programme at Risø DTU is among the world’s research leaders in organic solar cells – a cost-efficient alternative to silicon-based solar cells. The solar cell group is expanding in various scientific directions covering all possible aspects of organic solar cells. The Solar Energy Programme consists of a dynamical and versatile group of people with a positive team spirit.

A PhD scholarship in characterization of degradation and stability of new materials and compositions are available in the project “Organic-based photovoltaic cells with morphology control” supported by the Danish National Research Foundation (Grundforskningsfonden).

The performance of polymer solar cells is correlated with the nanostructure of the photoactive layer. To develop methods for optimizing performance, the first and foremost prerequisite is therefore knowledge of the desired nanostructure. The optimum active layer morphology of the organic solar cell is thought to consist of a bi-continuous network with an average electron donor/acceptor separation matching the diffusion length of the photo-generated electron-hole pair, usually taken as 10 nm. This nanostructure is referred to as a bulk heterojunction and is presently optimized by empirical methods.
The PhD student will be a part of the physics team focusing on methods for characterizing, modeling and predicting the nano-structure of polymer and hybrid solar cells.

Project description
The aim of the PhD project is to contribute to the necessary understanding of the correlation between photophysics and nanostructure of the bulk heterojunction. This will be achieved by using a combination of state of the art X-ray tomography at large scale facilities around the world, and more conventional scattering techniques at the X-ray facility of the Solar Energy Programme to derive quantitative, defining parameters for ideal bulk heterojunctions. Methods for applying the relevant X-ray techniques to both model devices and roll to roll coated devices on flexible substrates should be developed during the project.

Qualifications

• Master’s degree in physics, materials science, chemistry, engineering or a similar degree with an academic level equivalent to the master’s degree in engineering
• Experience with experimental techniques
• Good skills in mathematics, programming and data analysis
• Ability to work independently, to plan and carry out complicated tasks, and to be a part of a large, dynamical group
• Good communication skills in English, both written and spoken

We offer
We offer an exciting and challenging job in an international environment. Good possibilities for professional and personal growth. A family friendly organization with flexible working hours.

Approval and Enrolment
The scholarships for the PhD degree are subject to academic approval and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide.

Salary and appointment terms
The salary and appointment terms are consistent with the current rules for PhD degree students. The period of employment is 3 years. Employment will be as soon as possible. The place of work is Risø DTU in Roskilde.

Application
We must have your online application in English by 6 August 2010. Please open the link “apply online” and fill in the application form and attach your application, CV and information about academic grades.
