Researcher in nanowire solar cell development for space applications

Lund University was founded in 1666 and is repeatedly ranked as one of the world's leading universities. It has approximately 46,000 students and 8,500 employees in Lund, Helsingborg, and Malmö. We are united in our endeavor to understand, explain, and improve our world and human conditions. Lund University welcomes applicants with different backgrounds and experiences. Equality, equal opportunities, and diversity are fundamental principles for all parts of our operations. Description of the workplace The position is linked to the Department of Solid State Physics at the Department of Physics, a department with approximately 100 employees where extensive research is conducted, centered around various aspects of nano- and semiconductor physics, ranging from materials science to bio- and quantum physics with various applications. The department is a central part of NanoLund, which is Lund University's large interdisciplinary research center for nanoscience and nanotechnology. Also part of the operations is Lund Nano Lab, a central and shared facility for the fabrication of materials and components at the nanoscale. The department also has a strong commitment to undergraduate education, not least within the engineering program “Teknisk Nanovetenskap” at LTH. Tasks In this position, you will be responsible for the development of nanowire solar cells for space applications. The ZEUS project focuses on promoting the development of innovative and radiation-resistant nanowire solar cells with high efficiency. While current space-tested nanowire solar cells offer approximately 15% efficiency with single-bandgap cells, ZEUS aims to significantly improve this efficiency, potentially up to 47%, by using triple-junction nanowire cells using III-V semiconductor materials. The project aims to achieve scalability by transferring nanowire solar cells to lightweight, flexible substrates. The main goals include: Increasing the efficiency of radiation-resistant nanowire solar cells. Scaling up the substrate size to 100 mm^2 and developing modules with a size of 1x1 cm2. Reducing weight and material use through nanowire scaling and substrate reuse.

The project is an EIC Pathfinder-challenge project, which may require travel for project meetings and collaboration with the other partners within the project. The tasks include: In the tasks as a researcher, the primary component is to conduct research. The purpose of the employment is to develop one's independence as a researcher and to create conditions for further meritation. You will work with the synthesis of nanowires, surface passivation, and processing these into solar cells for space applications. Characterization of the nanowires and evaluation of these with respect to external quantum efficiency (EQE) and current-voltage characterization (IV), also inside a scanning electron microscope, will be part of the project. Qualifications Those who have obtained a doctoral degree are eligible to be employed as a researcher. Proof that the eligibility requirement is met must have been submitted no later than when the employment decision is made. Requirements for the employment are: obtained a doctoral degree in physics or chemistry very good knowledge of English, both oral and written experience of epitaxy, MOVPE, and nanowire growth of III-V materials experience of cleanroom and processing of semiconductor samples, such as wet etching, photolithography, metal evaporation, etc. good ability to work independently very good collaborative skills

Merit for the employment is: characterization of nanowire-based structures (I-V, EQE, PL, EBIC, photocurrent measurements) material characterization with EDX, SEM, TEM. fabrication of components at the nanoscale. previous meritorious post doc position, experience of continued research in a laboratory environment after graduation.
