Abstract
Quasi-mono silicon (Mono-like) (ML-Si) offers improved crystal quality over multicrystalline silicon (mc-Si) while maintaining lower production costs. Manufactured via directional solidification with seeded growth, ML-Si achieves a crystallographic structure comparable to Czochralski-grown monocrystalline silicon (Cz-Si). This study compares the physical and chemical properties of ML-Si, Cz-Si, and mc-Si using scanning electron microscopy (SEM), X-ray diffraction (XRD) and EDX analysis performed with SEM analysis. Results show that ML-Si closely matches Cz-Si in surface morphology and crystal orientation. The EDX spectra indicate that Silicon is the dominant element. After alkaline texturing, the reflectivity of ML-Si is approximately 5% higher (absolute) than that of Cz-Si across the 300–1200 nm range, but significantly lower than that of mc-Si. This reduced reflectivity compared to mc-Si, combined with its lower dislocation density and fewer grain boundaries lead to improved structural uniformity and superior optical performance. Consequently, ML-Si combines the economic benefits of high performance of Cz-Si and the cost advantages of mc-Si production, making it as promising material for high-efficiency, low-cost photovoltaic applications.
