- Abstract
- This study examined the flame-retardant properties of several encapsulant types that could replace existing ethylene vinyl acetate to improve the fire safety of Building Integrated Photovoltaic modules when used as exterior building material. For the study, six types of films (flame-retardant polyethylene terephthalate, polyether ether ketone, flame-retardant polyethylene naphthalate, polyimide, polyethylene, and thermoplastic polyurethane) were prepared, and various analyses were performed to determine the fire stability of each film. Thermogravimetric Analyzer results showed that polyimide and polyether ether ketone films had the best thermal stability. Upon measuring the light transmittance, polyimide and polyethylene demonstrated >90% light transmittance. The water vapor transmission rate value for the 50 μm-thick polyimide was 270 g/m2/day. Polyimide film did not ignite during the cone calorimeter measurement; instead, only film shrinkage was observed. Collectively, polyimide showed the best thermal stability and module application characteristics among all six types of films.
