| 摘要 |
The invention relates to a photovoltaic assembly (10) comprising a support substrate (12) consisting of silicon, a solar cell (26), in particular a solar concentrator cell, said cell having a first and a second solar cell contact (28, 30) and being connected to the upper face (38) of the support substrate (12) by means of the first solar cell contact (28), a pn-junction (46) that is integrated into the support substrate (12) in order to form a protective diode (14) comprising a first protective diode contact (16) and a second protective diode contact (20), said diodes being connected in anti-parallel to the solar cell (26). In order to design the contacts of the protective diode with as large a surface area as possible and to permit a simple contacting of the solar cell, the first and second protective diode contact (16, 20) form a first and second surface area (18, 22) respectively of the upper face (38) of the support substrate (12). |
