CELLULE SOLAIRE COMPORTANT DU SILICIUM MULTICRISTALLIN ET PROCEDE DE TEXTURISATION DE LA SURFACE DU SILICIUM MULTICRISTALLIN DE TYPE P |
摘要 |
<p>A solar cell of polycrystalline silicon (alloy) has a light-receiving surface containing pit-like holes of 0.1-10 mu m depth and 0.1-10 mu m diameter with a depth to diameter ratio of greater than 1, the surface area of the holes occupying more than half the surface area of the silicon. Also claimed is a process for texturing a surface of p-type polycrystalline silicon (alloy) by partial chemical oxidation of the surface with a fluorine ion-containing oxidising solution to form a porous surface layer which is then dissolved to obtain the textured surface.</p> |
