<p>Ceylan Zafer is a Professor in Department of Energy Technologies in Solar Energy Institute, Ege University, Türkiye. His research interests lie in the area of solution processable organic/hybrid materials for opto-electronic devices. These semiconductor materials possess a viable platform for printed, large area, flexible and wearable electronics that can be used as solar cells, smart windows, OLEDs, OFETs, sensors and bio-electronics, photo-catalysts. Professor Zafer is particularly interested in interface engineering for organic/hybrid solar cells, perovskite solar cells, dye sensitized solar cells, transparent solar cells for building integrated photovoltaics and stability/degradation studies for long lifetime perovskite and organic solar cells. He has led projects on i) Donor-Acceptor Low Band gap conjugated polymers for organic solar; ii) non-fullerene acceptors as ETL for perovskite solar cells; iii) upscaling and module fabrication of perovskite solar cells; and iv) Quantum Dot/conjugate polymer composites for opto-electronic devices. He spent nearly 25 years on the synthesis, characterization and utilization of organic and organometallic semiconductors for solar energy harvesting and optoelectronic applications. He has co-authored 70 SCI papers and 3 European Patents and more than 100 conference proceedings related to next generation photovoltaics.</p>
