Abstract
This seminar explores how nanoscale insights into colloidal interactions and interfacial chemistry contribute to the advancement of high-performance perovskite solar cells (PSCs). Precursor solution behaviour is examined using techniques such as Dynamic Light Scattering (DLS), Zeta Potential measurements, and X-ray Absorption Near-Edge Structure (XANES), revealing how charge distribution and coordination environments influence nucleation and film stability.
Atomic Force Microscopy (AFM) provides further understanding of the resulting film morphology and crystallinity, highlighting the role of nanoscale features in defect formation and charge transport. These findings inform targeted interface engineering strategies that lead to measurable improvements in device efficiency and operational stability, including under low-light conditions.
By connecting solution-phase dynamics with solid-state structure and performance, the seminar outlines a coherent approach to interface and colloid control, demonstrating their critical role in enabling scalable and efficient PSC technologies.
