We demonstrate the effectiveness of optimizing the shape (nanodisk, sphere, and hemisphere), aspect ratio, diameter, lattice constant, and thickness of the nanostructure. These modifications significantly improved the performance of silicon solar cells, resulting in a PCE increase by 15.27%. The optimal PCE was obtained from modifying anti-reflection using a nanodisk structure with a diameter of 300 nm, a lattice constant of 600 nm, and a thickness of 187.5 nm.

Examination of the optical microstructure of the SiC composite revealed a clustering of reinforcements within the matrix, potentially resulting from additional barriers formed during the stirring process that impede the movement of SiC particles.

Under excess Fe, Si stimulated cell wall POD activity and declined phenolics in monocot roots. The corresponding responses were much weaker in dicot roots.

Si is more efficient to substitute for lignin metabolism in monocots than in dicots under excess Fe.
