> These CdTe PV cells are not inherently semi-transparent; rather,
their transparency results from the spacing between thin strips of
opaque CdTe PV cells
...
> The wavelength-selec­
tive characteristic of these modules is achieved through the
use of a colored polyvinyl butyral (PVB) interlayer encapsulant
in the glass,36 which filters the light passing through the gaps be­
tween the PV cells.
