Recycling of a defective metal insulator semiconductor solar cell …
Large quantities of defective solar cells are rejected from production lines. By this study, we explore the methods for reusing silicon wafers of defective solar cells using metal insulator semiconductor (MIS) technology. For this, the insulating layers and the electrically conductive contacts must be totally etched. Also, we have to assure the ...
