DuPont, Oerlikon Develop New Solar Encapsulant PV5223

DuPont and Oerlikon Solar have collaboratedon the DuPont PV5223 – a new, ultra-thin white reflective solarphotovoltaic encapsulant sheet that is part of the DuPont PV5200 series.

According to the companies, the PV5223 white reflective polyvinyl butyral (PVB)encapsulant enables easier manufacturing of next-generation thin-filmphotovoltaic modules that reflect more sunlight back through the module, thus delivering more power.

Designed for use with OerlikonSolar’s Micromorph technology, the DuPont PV5223 white reflective PVBencapsulant sheet increases light reflectivity by more than 50% versuspaint, to an almost perfect 94% reflectivity, the companies state. Thenew ultra-thin (0.45 mm) encapsulant also is more than 40% lighter inweight than traditional 0.76 mm PVB encapsulants.
