DuPont™ Tedlar® frontsheet offers ideal protection for lightweight photovoltaic modules
Numerous commercial buildings and auxiliary structures are designed with little to no spare structural capacity. Vehicle efficiency is directly tied to weight. Lightweight modules may address this challenge by reducing weight, enabling photovoltaic (PV) elements to be installed or retrofitted at lower cost for parking roofs, building integrated PV (BIPV), and vehicle integrated PV (VIPV).
The main challenge for lightweight PV modules is replacing glass frontsheets while maintaining mechanical stability and weatherability.
For crystalline silicon cells, polymer frontsheets have been implemented to provide protection for supporting lattices like glass fiber reinforced polymer (GFRP) structures.
For thin film technologies like copper indium gallium selenide (CIGS), flexible substrates and polymer frontsheets have been applied as durable insulation.
Tedlar® film is an ideal solution for protective frontsheet of solar modules due to its unique balance of durability, UV resistance, high level of light transmittance, lasting UV protection, mechanical toughness, abrasion resistance, chemical resistance, good adhesion to encapsulant, easy cleaning, light weight and flexibility.
Transparent Tedlar® films have been used for decades in protecting graphics and signage and photovoltaic backsheets.
Building on years of successful performance, the new transparent Tedlar® TFS15BM3 film is designed to provide the highest level of outdoor stability and protection, offering a preferred and technologically advanced alternative to traditional glass.
