Yp. Zhang et Xs. Ge, A NEW METHOD FOR DETERMINATION OF THE OPTICAL-CONSTANTS AND THERMAL-RADIATION PROPERTIES OF SEMITRANSPARENT FILMS, Solar energy materials and solar cells, 37(3-4), 1995, pp. 379-387
It is believed that the use of transparent insulation materials (TIM)
is prospective in the fields of solar energy and architecture engineer
ing. Semi-transparent films are the basic constituents of some TIM, e.
g., honeycomb structure. Two most important characteristics of semi-tr
ansparent films are their transmittance for solar radiation and emitta
nce for long wave thermal radiation. In this paper, a technique for de
termining the optical constants of these films is presented. The therm
al radiation properties of several semi-transparent films are reported
.
