BACK-CONTACTED SOLAR CELLS WITH INTEGRAL CONDUCTIVE VIAS AND METHOD OF MAKING

Application 314/CHENP/2006 published 2007-09-14, filed 2006-01-25
Methods of manufacturing back-contacted p-type semiconductor substrate solar cells (10) fabricated using a gradient-driven solute transport process, such as thermomigration or electromigration, to create n-type conductive vias (18) connecting the n-type emitter layer (14) on the front side to n-type ohmic contacts (20) located on the back side, and back-contacted solar cells with integral n-type conductive vias, such as made by a gradient-driven solute transport process.
