TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The photovoltaic material comprises: crystalline silica; amorphous silica; cadmium telluride; cadmium sulfide; or copper indium gallium diselenium.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The adhesive layer is adjacent the front panel or adjacent to the back panel. The panel comprises at least two adhesive layers. The adhesive layer is continuous over the surface of the back panel or over the surface of the front panel. The front panel and the backing panel is glass. The front panel and the backing panel are flexible. The adhesive layer has a melt viscosity of greater than 500000 cP at 15 degrees C.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The composition comprises: a catalyst and an additional resin. The low crystalline poly- alpha -olefin is non-chlorinated. The low crystalline poly- alpha -olefin has: melting point of greater than 20 degrees C; and density of greater than 0.85, according to ASTM D 792. The alkoxysilane functional poly- alpha -olefin has a tensile strength of less than 100, preferably less than 10 MPa. The low crystalline poly- alpha -olefin resin has a water vapor transmission rate (WVTR) of greater than 5, preferably greater than 15 g/m2/day at a film thickness of 18 mils at 50 degrees C and 100% relative humidity. The alkoxysilane functional poly- alpha -olefin resin has a WVTR of greater than 0.1, preferably greater than 5 g/m2/day at a film thickness of 18 mils at 50 degrees C and 100% relative humidity. The composition is greater than 35 or at least 70 wt.% of the low crystalline polyolefin resin. The additional resin has a WVTR of greater than 0.1, preferably greater than 5 g/m2/day at a film thickness of 18 mils at 50 degrees C and 100% relative humidity. In the panel, the alkoxysilane functional poly- alpha -olefin has a tensile strength of less than 500 MPa. The elastomer is low crystalline poly- alpha -olefin. EXAMPLE - Di-n-butyl tin dilaurate (95%, 0.5 g) was mixed with ENGAGE 8842 (RTM: Ultra-low density ethylene-octene copolymer) pellets (49.5 g) in a plastic bag until the liquid was evenly spread over the surface of the pellets. The pellet mixture (3.5 g) was added to ENGAGE 8842 (RTM: Ultra-low density ethylene-octene copolymer) pellets (21 g) and mixed before charging the mixture into homogenizer for 2-5 minutes at 190 degrees C and 75 RPM. Then strips of VESTOPLAST 206 (RTM: Silane modified poly-alpha-olefin) (10.5 g) were added and mixed to obtain a film.
