PHOTO-VOLTAIC CELL AND METHOD OF MANUFACTURING SUCH A CELL |
| 摘要 |
A photo-voltaic cell, comprising a semi-conductor substrate, having a front surface and a back surface. Back surface field regions and emitter regions for collecting photo-current are provided, located alternatingly at the back surface of the substrate, at least one of the back surface field regions having a width of more than six hundred micrometer. A front floating emitter layer is provided at the front surface at least above said one of the back surface field regions, wherein the front floating emitter layer has an average electrical conductivity selected dependent on the width of said one of the back surface field regions. |
