Paragraph starter
The research by Diao et al. (2015) demonstrated that employing a microstructured printing blade to control fluid flow during the solution printing of all-polymer solar cells resulted in a significant increase in donor thin film crystallinity (approximately 90%) and a reduction in domain sizes. This improved morphology directly translated to enhanced solar cell performance metrics, including higher short-circuit current, fill factor, and open-circuit voltage, alongside reduced device-to-device variation. This highlights the critical role of engineered fluid dynamics in manufacturing processes for optimizing nanoscale material structure and achieving superior functional outcomes in electronic devices.
