PHOTOVOLTAIC SYSTEM INCLUDING LIGHT TRAPPING FILTERED OPTICAL MODULE |
| 摘要 |
A photovoltaic system that converts incident light into electrical energy that includes a light trapping optical module having a light randomizing dielectric slab with a first surface and a second surface, a first cell adjacent to the first surface of the slab that has a bandgap of lower energy than the energy of absorption onset of the dielectric slab, at least one filter element in optical contact with the second surface of the dielectric slab, and a sub-cell array with a plurality of photovoltaic sub-cells, wherein at least one of the sub-cells has a first surface that is in optical contact with the at least one filter element. |
