METHOD OF MANUFACTURING A SOLAR CELL AND SOLAR CELL THUS OBTAINED. |
摘要 |
<p>The manufacturing of the solar cell comprises the etching of a via hole (2) with a tapered shape such that the diameter (A) at a first side (1a) of the substrate (1), intended as a main side for capturing incident light, is larger than the diameter (B) at the second side (1b) of the substrate (1). The first doped region (3) extends to a first surface (11) in the via hole (2). The second doped region (5) is present at the second side (1b) of the substrate (1) and is suitably formed by ion implantation. The resulting solar cell has an appropriate isolation between first doped region (3) and second doped region (5) over a second surface (12) in the via hole (2) and is suitably provided with a deep junction between the first doped region (3) and dopant in the substrate (1).</p> |
