I am originally from Ethiopia and completed my Bachelor and Master degrees at Adama Science and Technology University (ASTU) in Materials Science and Engineering.

Currently, Metal-halide perovskites are rapidly emerging as the next-generation space photovoltaic (PV) technology with radiation tolerance significantly higher than the Si and III-V technologies and powering space solar panels. However, Space environment poses a very different set of extremes such as radiation, ultraviolet photons, extreme temperatures and temperature cycles and atomic oxygen causing performance degradation of the solar cell devices in space. To solve these problems, my research focuses on the development and optimization of halide Perovskite based single and multijunction-photovoltaics which is followed by advanced characterization of their stability and degradation in extreme conditions.

I am a Ph.D. student in the (Radiation-) Tolerant Electronics with Soft Semiconductors (ROSI) Group within the Soft Matter Physics Group at the University of Potsdam.  I earned both my bachelor's and master’s degrees in Chemistry at İzmir Institute of Technology. My research was focused on the design, synthesis, and characterization of colloidal carbon quantum dots and their applications during my master’s study. In addition, my research activities involved the synthesis and characterization of different shapes of colloidal plexcitonic nanocrystals with tunable optical properties in the visible region of the electromagnetic spectrum by using metal nanocrystals and different exciton sources. Currently, I am working on the Perovskite Single Crystal (PSC) based Radiation Detectors.

I am always fascinated by the light-matter interaction and physical phenomena behind it. I have studied on understanding and tune the structural, electronic, and optical properties of perovskites using both experimental methods and ab-initio simulations. Also, I studied graphene-based flexible photodetectors. Now, as a Ph.D. student, I am excited to move one step further and work on perovskite solar cells on ROSI Group and contribute to the development of renewable energy.

Thee has a background in embedded systems with experience in both industry and academia, having worked at Siemens and TU Berlin. He holds a Bachelor of Engineering from the Berliner Hochschule für Technik (BHT) and is nearing completion of his M.Sc. at TU Berlin in computer engineering. With expertise in satellite software and communication, his current focus is on testing perovskite solar cells on nanosatellites.
