Lecture: Understanding and advancing perovskite materials toward stable and efficient optoelectronics by Prof. dr. Elke Debroye

ABOUT THE LECTURE 

Metal halide perovskites have emerged as a highly promising class of semiconductors for
optoelectronic applications due to their exceptional light absorption, tunable emission and efficient charge transport. These cost-effective materials have demonstrated an unprecedented rise in solar power conversion efficiency, surpassing 25% within a decade, outpacing conventional silicon photovoltaics. However, fundamental insights into their intrinsic photophysical properties remain incomplete, yet are crucial for further performance enhancements. Additionally, while the impressive efficiency of novel perovskite materials is often emphasized, their long-term stability is equally vital for practical implementation.
 
In this talk, Prof. dr. Elke Debroye will present the development of perovskite systems with diverse compositions, structures and morphologies using various synthesis strategies. By employing advanced spectroscopic techniques, they elucidate the interplay between crystalline structure and charge carrier dynamics that dictate their optoelectronic performance. Additionally, photoluminescence (PL) microscopy imaging is being exploited correlating materials’ photochemistry and intrinsic defects to optoelectronic device performance, providing direct insight into their function in real-world applications.

Prof. dr. Debroye will demonstrate how chemical micro-engineering can optimize perovskite
stability and functionality, with a focus on improving X-ray detection performance. Finally, she will
present strategies for fabricating high-quality photoactive layers, including controlled film
deposition, as critical components for next-generation stable optoelectronics.
