The theory of DASC was first presented by
Minardi and Chuang (1975). In the DASC, the heat transfer
fluid flows between the bottom wall and the glass cover
at the top, as shown in Fig. 2. The focus of this article is
limited to reviewing research papers in the field of FPSCs.
The major fraction of the incident solar radiation passing
through the FPSC’s transparent cover is absorbed by
the absorber plate. The bottom and sides of the collector’s
absorber plate are fully insulated to minimize heat losses by
conduction. The collector’s glass cover diminishes heat losses by convection via containment of an air layer and by
radiation in that it is transparent to the sun’s shortwave
solar radiation but practically non-transparent to the
long-wave thermal radiation emitted by the absorber plate
(greenhouse effect)
