PROCESS FOR THE PRODUCTION OF SOLAR CELLS HAVING A LOCAL BACK SURFACE FIELD (LBSF) |
| 摘要 |
The present invention relates to a method for producing solar cells with local back surface field (LBSF) using an alkaline etching paste which allows the back surface to be polished and the back surface edges to be insulated in a single process step. |
