<b><span style="color:#1F497D">Abstract</span></b><span style="font-size:11.0pt; font-family:"Calibri","sans-serif"; color:#1F497D">:</span><span style="color:#1F497D"> Halide (hybrid) perovskites (HaP) have emerged as a new class of semiconductors that truly
encompass all the desired physical properties for building optoelectronic and quantum devices such as large tunable band-gaps, large absorption coefficients, long diffusion lengths, low effective mass, good mobility and long radiative lifetimes. In addition,
HaPs are solution processed or low-temperature vapor grown semiconductors and are made from earth abundant materials thus making them technologically relevant in terms of cost/performance. As a result, proof-of-concept high efficiency optoelectronic devices
such as photovoltaics and LEDs have been fabricated. In fact, photovoltaic efficiencies have sky rocketed to 24% merely in the past five years and are nearly on-par with mono-crystalline Si based solar cells. Such unprecedented progress has attracted tremendous
interest among researchers to investigate the structure-function relationship and understand as to what makes Halide hybrid perovskites special?</span></p>

<span style="color:#1F497D">In my talk, I will attempt to answer some of the key questions and in doing so share the results from our work on HaPs over the past four years in understanding structure induced properties of HaPs. I will also highlight fundamental
bottlenecks that exist going forward which present opportunities to create platforms to understand the interplay between light, fields and structure on the properties of perovskite-based materials. </span></p>

properties in materials with the aim of controlling charge and energy flow across. His research philosophy is applying creative and “out-of-the-box” approaches to solve fundamental scientific bottlenecks and they utilize the knowledge to demonstrate technologically
relevant performance in devices that is on par or exceeds the current state-of-the-art devices. He has published more than 130 peer reviewed papers in journals such as Science, Nature, Nature Materials, Nature Nanotechnology, Nano Letters, ACS Nano, Chemical
Society Reviews, Applied Physics Letters and Advanced Materials amongst others. He has also delivered more than 85 invited talks.
