Nanoscale Graded Nitrogen‐Doping of TiO2 via Pulsed Laser Deposition for Enhancing Charge Transfer in Perovskite Solar Cells (Small 52/2024)
Source abstract
Abstract
Perovskite Solar Cells Nitrogen doping of TiO2 thin films through pulsed laser deposition enables in-situ nanoscale graded doping across the film thickness. Precise control of the nitrogen-to-oxygen ratio within the films results in highly transparent layers with tailored electronic band alignment. The doping gradient creates a cascaded shift in the conduction band minimum, effectively bridging band offsets and enhancing electron transport. This approach offers an efficient strategy to facilitate carrier transport in perovskite thin-film solar cells, improving their overall performance.
