Job description:

The rapid increase of the conversion efficiency of perovskite solar cells due to their enormous potential provides a very promising possibility to improve the efficiency of various solar modules significantly to potentially over 35%. For an efficient extraction of the charge carriers, interconnection lines of thin-film solar modules are necessary. However, they reduce the active area of the solar modules and thus lower their overall efficiency.

Laser-scribing of interconnection lines of Perovskite thin-film solar modules has already been demonstrated to be a promising technique for high accuracy low-cost interconnection fabrication. Nevertheless, it raises new challenges regarding ablation mechanism, debris redeposition and degradation due to heat. Therefore, a laser beam induced current (LBIC) measurement setup is envisaged to provide detailed information about the local current generation of laser-scribed perovskite solar modules.

The scope of work includes the installation of necessary LBIC setup components, creation of a setup control program (LabVIEW) including a clear UI and the validation of the setup’s functionality. The work concludes with a subsequent experimental study of dead areas on self-made laser-scribed perovskite modules.

The facilities of the Institute of Microstructure Technology will provide a perfect environment for insights in interdisciplinary work between physics, mechanical and electrical engineering. The candidate will get the opportunity to work in a young and highly motivated international team and will get precious experience.

We are looking for a candidate with a strong affinity for development and experimental work. In addition, a fundamental understanding of refractive optics is indispensable. The ideal candidate should have a strong drive to engage with research activity that often implies addressing novel challenges. Prior experience with LabVIEW as well as lab experience will be advantageous. This is a multidisciplinary project, so a will to broaden horizons and strengthen a diverse set of skills is also desirable.
