TECHNOLOGY FOCUS - POLYMERS - Preferred Polymer: In the polymer, the micro-domains and clusters formed in the volume of the polymer material have a size from 5 to 150 micron. The nano domain and clusters formed in the volume of the polymer material have a size from 20 to 100 nm. The polymeric encapsulating layer is made of a compound of derivatives of polyurethanes that are based on polyurethane oligomers. The polymeric encapsulating layer is made of a compound of derivatives of polyurethanes that are based on epoxy-urethane oligomers. The composition is includes metal dopants, where the metal dopants are made from materials which include the ions of at least one of lead (Pb), cobalt (Co), zinc (Zn), copper (Cu) or made from metal powder. The encapsulating layer is formed as a result of the flowing the composition onto the front face surface of the optical device. The encapsulating layer is formed as a result of the dispersion of the composition onto on the front-face surface of the optical device. The optical devices where the forming an encapsulating layer are include the photovoltaic modules, optical devices with a complex configuration, concentrated systems for photovoltaic modules including plastic lenses, the Fresnel lens's, in microreplication, an interlayer between glass and bullet-proof windows. Preferred Module: In the photovoltaic module, each of the photovoltaic cells is made of at least one of mono-crystalline silicon, multi-crystalline silicon, amorphous silicon, nano-crystalline silicon or non-silicon materials, including dye-sensitized solar cell and organic solar cells. Each in this module of the photovoltaic cells is based on copper indium gallium selenide (CIGS) and at standard conditions (illumination: 40000 Lx; lambda max=550...650 nm) open circuit voltage of the photovoltaic module is higher as 9-14% and more as compared with Photovoltaic modules that are based on CIGS and does not laminated with any materials. Each of the photovoltaic module is based on CIGS and at conditions illumination less then 1200 Lx, lambda max=380...450 nm the open circuit voltage of the photovoltaic module is higher as 55-75% and more as compared with Photovoltaic modules that are based on CIGS and does not laminated with any materials. The substrate includes a metal sheet covered by an electrically insulating layer and aluminum foil is used as a metal, and an anodized layer of the aluminum serves as an insulator. The substrate includes a polymeric sheet coated by metallic layers for providing electrical contact. The transparent film of conductive oxide metal is affixed between the flexible optically transparent cover and front-face surface of the photovoltaic cell module. The encapsulating layer is further defined by a film presenting a flat coat surface morphology or relief/crinkle coat surface morphology presenting a random rounded ridge and valley structure where the radii of curvature of the concave and convex features of the structure are between approximately 0.3 mm and 2.5.mm.
