New horizons of photovoltaics: Preparation, characterization, and limitations of thin-film halide perovskites
The Institute of Materials Chemistry invites you to a lecture from Advanced Materials Seminar series, which will take place in lecture hall P8 at the Faculty of Chemistry on Monday, April 28, 2025, at 12:00 PM. The lecture will be given by RNDr. Zdeňka Hájková, Ph.D., from the Institute of Physics of the Czech Academy of Sciences in Prague.
Organic-inorganic. Halide. Thin-film. Efficient. Cheap. Unstable. Such are the perovskites that will be discussed. Over the past decade, halide perovskites have become true photovoltaic superstars. With efficiencies exceeding 26%, they are quickly catching up with silicon solar cells and pointing the way toward cheaper and more accessible solar energy. This overview lecture will explore what makes perovskites so exceptional. You will get to know them from the A-site in their structure to their near-ideal band gap for photovoltaics. We will also look at methods of preparing perovskite thin films, particularly the easy deposition from solutions. Then we will compare which microscopic methods are best suited for characterizing the prepared layers. Attention will also be paid to key scientific challenges, especially those related to the instability of perovskites and their content of toxic lead. The talk will be accompanied by material samples – that is, if they don’t degrade on the way from Prague...
