Title: Carrier dynamics and transport in colloidal quantum dot arrays

Abstract: Colloidal quantum dots are an emerging type of solution-processed semiconductors that offer a powerful platform for the scalable manufacturing of optoelectronic devices. Understanding carrier dynamics and transport in nanocrystal is crucial for unlocking their full potential for optoelectronic applications. In this talk, I will discuss the impact of energetic polydispersity on carrier dynamics, and the influence of imbalanced carrier transport on solar cell performance. I will present the direct visualization of non-equilibrium carrier propagation in PbS quntum dot arrays, and how this can be controlled and optimized through novel materials processing and heterostructuring. These findings offer promising strategies to harness transport phenomena for more efficient optoelectronic devices.
