Abstract
A solar cell has a substrate made of a textile planar structure. The textile planar structure is assembled from light transparent glass-fiber threads and electrically conductive, but non-transparent carbon-fiber threads. The glass-fiber threads serve as spacers and fillers for the carbon-fiber threads, so that sufficiently light transparent, closed interstices are created between the carbon-fiber threads, whereby the light can pass through the substrate. Semiconductor layers, which form a blocking layer in-between, are located on both sides of the thus-formed substrate. One electrode is generated by the carbon-fiber threads of the substrate.

1-14. (canceled)
A solar panel (1) comprising:
- a substrate (2) having first and second major sides and side edges and being transparent and electrically conductive,
- a first doped semiconductor layer (5) arranged on the first major side of the substrate (2),
- a second doped semiconductor layer (7) arranged on the first doped semiconductor layer (5) and forming a pn-junction with the first doped semiconductor layer (5),
- a third doped semiconductor layer (6) arranged on the second major side of the substrate (2) and being of a same conductivity type as the first doped semiconductor layer (5), and
- a fourth doped semiconductor layer (8) arranged on the third doped semiconductor layer (6) and forming a pn-junction with the third doped semiconductor layer (6),
- wherein the substrate (2) comprises a woven fabric, a knitted fabric or a knotted fabric.
