Available in PDF, EPUB and Kindle. Book excerpt: Selected plastic films which had possible application as encapsulants for thin-film cadmium sulfide solar cells were irradiated in vacuum by ultraviolet light below 3000 angstroms for various lengths of time up to 5266 hours. The light intensity was between 0.67 and 1 times the integrated solar intensity below 3000 angstroms at 1 astronomical unit. The change in optical trans-mission with irradiation time was measured from 0.35 to 2.7 microns, and changes in percent elongation and breaking strength were measured at room temperature. Of the films tested, the most resistant to damage was H-film, a polyimide, and weather-durable Mylar was the next most resistant.

This book was released on 1974 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past several years, the President of the United States has made the utilization of solar energy a national goal. The National Science Foundation was given the task to coordinate Federal activities in solar energy research and technology. One of the general objectives of this program is "to provide the research and technology base required for the economic terrestrial application of solar energy; and, to foster "the implementation of practical systems to the state required for commercial utilization." The National Oceanic and Atmospheric Administration, in cooperation with the National Science Foundation, held a Solar Energy Workshop on November 29-30, 1973. The objective of the workshop was to identify the requirements of the solar energy community by means of discussions among specialists in solar radiation technology. A first draft of its recommendations to Working Group 1 appears in Attachment #1.

Book Synopsis Influence of Uv Radiation and Vacuum on Strength and Destruction of Polymer Films by : L. M. Polyakov
Download or read book Influence of Uv Radiation and Vacuum on Strength and Destruction of Polymer Films written by L. M. Polyakov and published by . This book was released on 1967 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of UV radiation on the mechanical properties of poly(ethylene terephthalate) (PETP) films was studied. The changes were noted in tensile strength and deformation, and the formation of defects, i.e., cracking. The samples used were strips of PETP film, 6 mm wide, 20 mm long and 10 microns thick. The irradiated samples were subjected to tensile strength tests on a special machine. It was found that open cracks developed on the irradiated side of the samples if the irradiation took place in air. Vacuum-irradiated samples developed cracks only on deformation during the tensile test. A weakening of molecular bonds during the irradiation was assumed. Cracking began at definite stresses and deformation which decreased with an increase in the radiation dose. The tensile strength and plasticity of the irradiated films decrease with an increase in the duration of irradiation. The air-irradiated samples display a higher loss in tensile strength than the vacuum-irradiated samples, which suffer a higher loss in plasticity. Vacuum-irradiated samples form no visible defects on the surface: their surface remains smooth even after rupture of the sample. (Author).

This book was released on 1962 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analytical studies and experimental results are presented to show the gross effect of extreme uv radiation (1100 to 1850 angstroms) on materials in ultrahigh vacuum. Experimental results on the irradiation of selected metals, plastics, and paints, indica ed that the effec s of 1100 to 1850 angstrom radi tion upon materials are small and are similar to effects caused by uv radiation of longer wavel gths. Only the high quantum yields for photo-emission are unique for the extreme ultraviolet range. (Author).
