CINE Conference 2021: "Light Energy Conversion with Semiconductor Nanostructures: From Quantum Dots to Perovskites", by Dr. Prashant Kamat, University of Notre Dame

Semiconductor nanostructures with tunable photoresponse can capture the visible and near IR photons quite effectively. By controlling the size and composition one can tune the photoresponse of semiconductor nanostructures in the entire visible region. The key advantage of semiconductor nanostructures lies in designing thin film solar cells with low temperature processing. These advantages significantly decrease the energy payback time since less energy is consumed (and hence a lower carbon footprint) during their manufacture. The early studies which focused on the synthesis of semiconductor quantum dots and elucidation of charge carrier dynamics have led to the evolution of high efficiency metal halide perovskite solar cells. In the present talk light induced charge carrier generation and transport across interfaces which are important in the operation of solar cells will be discussed. Recent developments in utilizing semiconductor quantum dots in light energy conversion will be discussed.
