The present disclosure provides a solar module including an encapsulation layer, a plurality of solar cells embedded in the encapsulation layer with gaps between the solar cells; and a first patterned layer formed on the encapsulation layer and corresponding to locations of the gaps so as to absorb the light penetrating through the gaps, thereby shielding buildings from sunlight and thus saving energy.

Laminated (and, in some cases, additionally etched) glazing units for cooperation with solar-energy systems during architectural integration thereof include an optically-transparent substrate in contact with an incident medium, on one side, and with a non-quarter-wave thin-film-stack based interference filter on another side, followed by an exit medium. Embodiments are practically applicable to conceal physical structures disposed behind them and characterized by IR-light transmittance that is enhanced (as compared with conventional glazing units based on quarter-wave thin-film-stacks and similarly utilized) to improve efficiency of a solar-energy system carrying at least a portion of such glazing unit on its front surface. Colour of reflected light perceived as a function of angle is sufficiently stabilized for practical applications. In specific cases, a solar-energy system is integrated inside or with such a glazing unit.

The present invention relates to a lamination process for producing a multilayer laminate, preferably to a lamination process for producing a photovoltaic (PV) module, and to a PV module laminate.

A light redirecting film defining a longitudinal axis, and including a base layer, an ordered arrangement of a plurality of microstructures, and a reflective layer. The microstructures project from the base layer, and each extends across the base layer to define a corresponding primary axis. The primary axis of at least one of the microstructures is oblique with respect to the longitudinal axis. The reflective layer is disposed over the microstructures opposite the base layer. When employed, for example, to cover portions of a PV module tabbing ribbon, or areas free of PV cells, the films of the present disclosure uniquely reflect incident light.

The present invention is applied to photo voltaic module enhanced light. In particular, the present invention relates to glass-glass and back contact photo photovoltaic modules with enhanced conversion efficiency in areas that are not usually active.

A semi-transparent solar panel apparatus for allowing light to pass through solar panels onto crops to maximize solar collection areas includes a plurality of cell columns comprising a plurality of solar cells. Each cell column has a space between the adjacent cell columns to allow light to pass therethrough. A pair of encapsulant sheets is coupled together on either side of the plurality of cell columns to maintain the arrangement of the cell columns. A bottom frame is coupled to the pair of encapsulant sheets. The pair of encapsulant sheets is coupled to a bottom horizontal portion within a bottom vertical portion. A top frame is coupled to the bottom frame with a top vertical portion coupled to the bottom vertical portion of the bottom frame to seal the pair of encapsulant sheets between a top horizontal portion and the bottom horizontal portion.

A photovoltaic module for transforming an incident light into electrical energy includes plural solar cell configured to transform the incident light into the electrical energy; a first sheet that is transparent to the incident light; and a second sheet that is transparent to the incident light. The plural solar cell are sandwiched between the first sheet and the second sheet. At least one of the first and second sheets has a high transparency regarding the incident light and also a high scattering of the incident light.

The present disclosure provides a photovoltaic module, which comprises a photon absorbing material comprising a solar cell; The photovoltaic module also comprises a glass material positioned within a plane and being positioned over the photon absorbing material such that in use light is incident on the glass material and the glass material transmits light towards the photon absorbing material, the glass material having a front surface facing away from the photon absorbing material. The front surface of the glass material has a shape which is profiled such that the emittance of infrared light from the front surface of the glass material is increased compared to that of a flat front surface, the emittance of the infrared light being associated with absorbance of infrared light that is incident upon the front surface. A rear backing sheet of the photovoltaic module may have a shape that is profiled in a corresponding manner.

The present invention relates to polymer conductor sheets comprising zones featuring different degrees of polymerization and/or crosslinking within the same polymer sheet, wherein the zones differ, for example, in mechanical stability, ductility and/or (thermo)adhesiveness. The present invention also teaches devices comprising these zoned polymer conductor sheets such as solar cell strings, matrices and modules, uses thereof and methods for producing these.
