Dr. İlker Doğan received his M.S. degree in physics from the Middle East Technical University, Ankara, Turkey, in 2008, and Ph.D. degree in applied physics from Eindhoven University of Technology, Eindhoven, The Netherlands, in 2014. During his Ph.D. he focused on the plasma physics and materials processing in plasmas, particularly for silicon nanocrystals for photovoltaic and energy storage applications. He is working in TNO, part of the Solliance consortium as a researcher, and leading the flexible perovskite photovoltaics activities. His perspective is to promote the perovskite thin film technology to large scales, using relevant upscaling technologies, such as sheet-to-sheet (S2S) and roll-to-roll (R2R) coating routes. His main research interests related to perovskite PV is the development of uniform large area absorber and transport layers, investigation of upscalable materials and environmentally benign solvents, and module characterization.

Slot-die processing of large area perovskite modules for hybrid tandem applications

Mixed metal-halide perovskite solar cells (PSC) are advancing in power conversion efficiency (PCE) faster than any other photovoltaic technologies, reaching up to 25.5% [1]. However, the reported record efficiencies are obtained with lab-scale devices. Promoting this technology to the market level with efficient and stable devices manufactured with cost-effective, industrially scalable processes is the persisting challenge. In this talk, we will demonstrate the activities within TNO-Solliance towards large scale, stable rigid and flexible perovskite modules. A specific attention will be given to the semitransparent perovskite modules, and their application in bifacial tandem technologies.
