Schueco has launched an up-rated version of its ProSol TF module, claiming a 30% increase in electrical output over its standard offering. The new thin-film module, ProSol TF+, is a tandem junction module capable of being customized for a range of BIPV applications.
BIPV applications demand flexibility in the PV module having both an aesthetic and functional role. However, increasingly there is a need to demonstrate higher conversion efficiencies for ROI requirements.
The ProSol TF+ is a tandem junction silicon thin-film cell design. As a result the surface is of deep anthracite colour, meeting many aesthetic requirements in BIPV applications. However, in addition to a standard rectangle form factor, the modules can, for the first time, be specified in a variety of alternative shapes including triangles, parallelograms and rhomboids. This greatly extends the system's design possibilities for architects. While the modules are supplied opaque for maximum power output, they can be customized by laser-cutting to present varying degrees of transparency ranging from 5% to 25%. This makes them particularly versatile not only from a user point of view, but also from an architectural design perspective.
ProSol TF+ modules are available either as single glass panes for use in Schueco rainscreen façade systems or as part of double- or triple-glazed units incorporated into Schueco insulated façade systems such as FW 50+.SI.
The ProSol TF+ is typically 80Wp/m2, employing a tandem cell structure that incorporates dual layers of microcrystalline and amorphous silicon, together with a special laminate foil (PVB). As well as generating electricity, ProSol TF+ can act both as insulation and as solar shading, resulting in a significant reduction in the need for heating and air-conditioning. Sizes range from 200mm x 300mm up to 2300mm x 2600mm with even larger sizes being possible using a 'patchwork' technique.
