Project Description
Tin perovskites are interesting for several optoelectronic applications. They have complementary absorption to Lead ones for photovoltaic applications, and they offer a more environmentally friendly materials aspect. However, there are significant challenges with Tin based perovskites and their stability issues are not yet fully understood. This project aims to understand the degradation pathways for Tin based perovskties for the use of photovoltaic applications. The project will explore several tin-lead compositions and their corresponding films via optical, electrical and physical characterization tools exist under KAUST umbrella.

Research Interests
a€‹Professor Baran's research interests lie in the area of solution processable organic/hybrid soft materials for electronic devices. Such soft semiconductor materials possess a viable platform for printed, large area, stretchable and wearable electronics that can be used as solar cells, smart windows, OFETs, thermoelectrics, sensors and bio-electronics. a€‹Professor Baran is particularly interested in interface engineering for organic/hybrid solar cells, transparent solar cells for building integrated photovoltaics and stability/degradation studies for long lifetime organic solar cells. She has led projects on i) conjugated polymers for electrochromic devices; ii) non-fullerene acceptors for organic solar cells; iii) multi-component and multi-layered solar cell devices; and iv) understanding the correlation between recombination and nano-morphology in solution processed solar cells. Professor Baran aims to expand the applications of solution processable organic/hybrid semiconductors and to explore their limits in organic/hybrid thermoelectric devices and bio-electronics in the future.Selected Publications
