Operando Perovskite Characterization
What Optical Microscopy Can Reveal in Working Devices
Webinar about Solar Cell Performance
In this webinar, Dr. Sudipta Seth will talk about advanced optical microscopy and spectroscopy that interrogate halide perovskite materials and corresponding optoelectronic devices under relevant in-situ and operando conditions. This approach uncovers the local fields, transport bottlenecks, and defect chemistry that set solar cell performance. He will show how these local optical signatures translate into a mechanistic understanding of device operation, and how that understanding feeds back into the design of better probes, interfaces, defects, and devices.

From Local Material Dynamics to Device Performance
The performance of optoelectronic materials and devices relies on carrier transport, recombination, ion migration and phase segregation. They unfold on length scales from nanometers to micrometers and timescales from picoseconds to hours. Conventional characterization averages over this heterogeneity and rarely captures these events in operational devices.
Optical microscopy and spectroscopy can recover this hidden picture. They convert local material function directly into optical contrast, and that contrast can be resolved across the length and time scales where the function actually happens.
For Materials Scientists
The talk is aimed equally at materials scientists curious about what happens inside their samples and at microscopists and spectroscopists looking for new problems suited to their tools.
