Abstract
An optoelectronic device assembly can include: a coated element and an electroactive cell on the coated element, wherein the electroactive cell is selected from the group consisting of a light emitting diode and a photovoltaic cell. The coated element can include: transparent thermoplastic substrate and a protective weathering layer. The transparent thermoplastic substrate can include a material selected from the group consisting of aromatic polycarbonate and polyester, and combinations including at least one of the foregoing materials. The protective weathering layer can have a UV absorbance loss rate at 330 nm of less than or equal to 0.15 A/year as estimated from filtered xenon arc exposure and/or having a rate of erosion of less than or equal to 5 μm per year as estimated from filtered xenon arc exposure.
