  • Abstract
    Spheral solar technology consists of silicon spheres embedded in aluminum foil. Sphere processing consists of obtaining metallurgical-grade silicon feedstock in the form of irregular shaped particles, melting them into spheres, upgrading them in purity, and diffusion. Cell processing consists of bonding the spheres to a perforated foil, exposing the core, and applying an insulator and a backfoil to complete the cell. Flexible 10 cm2 solar cells of 10 cm2 are repeatably produced with average and peak efficiencies of 10% and 11%, respectively
