Optimization of Open-Air Spray Coating Parameters for a Robust and Scalable SnO2 Electron Transport Layer in Perovskite Solar Cells
This research optimizes open-air spray-coating parameters for nanoparticle tin oxide to create a scalable, fullerene-free electron transport layer (ETL) in inverted p-i-n perovskite solar cells. Traditional organic ETLs hinder commercialization due to high costs and poor stability. Spray parameters (i.e. substrate temperature, flow rate, wt%, nozzle distance, etc.) are fine-tuned to optimize film morphology. Films are characterized via profilometry, optical microscopy, and computer vision before a hyperparameter optimization model reduces the parameter space to converge on an optimal parameter set. This foundational work enables future performance validation within full-stack cells to confirm solar cell performance and long-term device stability.
