Abstract

Background Multi-crystalline silicon remains crucial for cost-effective photovoltaic manufacturing. Directional solidification furnaces enable large-volume ingot casting with control. Objective This study investigates furnace-controlled growth mechanisms for multi-crystalline silicon. It focuses on heat transfer, impurity transport, and stress formation. Methods A simulation-led furnace workflow is outlined for interface stabilization. Thermal fields are interpreted using design–stress relationships from literature. Impurity and SiC behaviour are mapped to process configuration choices. Results Reported studies show crucible properties reshape melt interface geometry. Optimized heat transfer improves crystal quality under vacuum systems. Furnace design changes reduce thermal stress and defect susceptibility. Comparison with Literature Impurity reduction strategies align with crucible cover optimization reports. Carbon–oxygen transport modelling supports contamination control approaches. SiC formation and engulfment mechanisms support cleanliness-focused redesign. Conclusion Directional solidification performance depends on coupled thermal–chemical control. Furnace optimization can improve quality, stability, and manufacturability outcomes.
