On the other hand present thin-film silicon solar cells and modules are not suited for higher light intensities—i.e., for applications with sunlight concentration. As for the angle of incidence of the incoming light, it evidently also has, for optical reasons, an influence on the efficiency of the solar module.
Sketch (not drawn to scale) showing basic structure of a single-junction thin-film silicon solar cell in the “superstrate configuration.” The thickness of the glass–TCO combination is basically determined by the glass thickness, ranging from 0.5 to 4 mm, whereas the TCO layer thickness is typically around 1 µm.
Deposition of thin-film silicon solar cells on stainless steel has the advantage of being relatively straightforward. Increasingly one attempts to use polymers as substrates. Here solar cell deposition is more difficult, because it is impaired by outgassing from the polymer and by temperature limitations of the latter.
5.1. General principles In thin-film silicon solar cells, one so far almost exclusively uses two-terminal tandem solar cells. These devices stack two subcells, one on top of the other as indicated in Fig. 25.
For all types of p–i–n- and n–i–p-type thin-film silicon solar cells, it is of paramount importance to have a strong internal electric field and to avoid substantial reduction of this field by any of the effects listed earlier.
