Photovoltaic Films

Thin-film photovoltaic(PV) modules are manufactured by depositing ultra-thin layers of semiconductor material onto a low-cost backing such as glass, stainless steel or plastic.

Photovoltaic systems are exposed to extremes of weather including cold, heat, moisture and UV radiation.

Economics can’t be ignored and all new solutions must be cost-effective following the recent industry re-structuring and the highly competitive nature of the solar panel markets. Any new component should ideally be a drop-in solution that can be used on existing equipment.

The polymer components of photovoltaics are critical in terms of durability, weathering, light transmission and protection of the silicon component as backsheets, frontsheets.

These materials can offer direct benefits in terms of performance and overall economics including assembly and mounting, as well as increased flexibility for applications such as building integrated photovoltaics and portable solar cells for charging electrical devices.

Barrier layers that protect thin-film solar cells from oxygen and water vapor and thus increase their useful life are an essential component.

The advantages of  polymer-based plastic films

"The films are considerably lighter -- and flexible. They make new production processes possible that enable significant reductions in the cost of manufacturing a photovoltaic module." Instead of working with individual glass plates, the solar cells could be printed onto a plastic film and then encapsulated with the barrier film: photovoltaic modules on a roll.

Second generation thin film photovoltaics incorporate backsheet material, typically a film product to replace the traditional glass module backing. These thin film photovoltaic backsheets can be engineered with properties to increase cell efficiencies, like reflectance and dielectric strength, as well as act as a barrier to ensure a long life of the module.

Regardless of the thin film technology, thin film photovoltaic backsheets are designed to aid in the production of lowest cost-per-watt modules, conform to non flat surfaces promoting module flexibility and create a high vapor barrier to protect the thin film PV chemistry.

Photovoltaic Front sheets are used as a protective barrier for the interior components of the PV module. Critical film requirements include low water vapor permeation and excellent UV resistance, a high degree of visible light transmission.

We offer both backsheet laminates and front sheet films for second generation thin film photovoltaic module applications which are available with a robust construction in a range of thicknesses, widths, and surface textures to meet virtually any design configuration and production requirement.
