i+k] = output value at time i+k Greek symbols [alpha] = short-wave absorptance of the PV surface [[DELTA]U.
The method requires bidirectional optical measurements of nonspecular layers such as shades or blinds, use of optical data for specular glass layers, and matrix layer calculations to combine these individual layer properties to produce overall window system transmittances and layer absorptances from which solar gains can be computed as a function of incident direction.
[FIGURE 4 OMITTED] This transfer-matrix method has been used to analyze reflectance, transmittance, and absorptance of optical multilayer accurately.
Thus spectral issues related to cavity absorptance are probably very small to begin with (at least for pre-flight cavities) and have already been corrected.
Absorptance of the visible light (400 - 700 nm) was the highest during May followed by April.
The solar absorptance coefficients have been set to 0.
They consist of a composite cover film with high emissivity and low visible absorptance, and a low-emissivity surface adhered to the S/C.
