Thin-film Photovoltaic Glazing for BIPV solutions

Polysolar uses thin-film PV technology to manufacture our BIPV solar glass. The material is ideal for building integrated solutions, enabling us to produce transparent or opaque solar PV panels, ideal for façades, canopies, skylights or curtain walls. Designed specifically for BIPV applications, thin-film technology offers performance advantages through:



Thin-film can operate to a high efficiency at non-optimal angles therefore offering greater potential for installation locations such as the vertical side of a building.

Thin-film operates down to 10% of sunlight, extending the number of hours over the year in which to produce electricity providing a more consistent energy yield. Additionally thin-film alignment makes panels less affected by shading.

Panels are less affected by high temperatures so don't require ventilation for optimal operation. Furthermore thin-film works at a higher efficiency over a greater temperature range meaning maximum potential energy production.

Initial installation costs similar to conventional building materials but additional multi-functionality makes thin-film photovoltaic glass economically superior.

Tough and rigid panels with laminated glass increase the panel's functionality and potential for installation applications.




With thin-film the active material is deposited as a thin, naturally translucent layer on a conductive glass substrate. We manufacture our BIPV panels by vacuum depositing an ultra-thin film of the PV absorber on a conductive transparent conductive oxide (TCO) glass surface and then laminating another glass sheet on top.
