Research
My research focuses on next generation solar devices that could prepared using easy manufacturing methods and cheap materials. Besides development of novel materials for flexible solar cells and upscaling the technology, I study the lifetime issues of these technologies and sustainability of the approaches. Regarding the latter topic, my research lies in utilizing abundant and renewable materials such as wood-derivatives. Overall, I am interested in how increase of renewable energy production changes the future energy systems.
Teaching
I am the responsible professor for the bachelor and master programs in materials engineering. My personal focus area in teaching is energy materials. I have full formal qualifications in higher education pedagogics.
