  • Multilayer down-converting encapsulant films and electronic devices including the same
    Patent number: 10424682
    Abstract: A multilayer encapsulant film having at least two layers includes a first layer comprising an encapsulant resin, and a second layer comprising an encapsulant resin and at least one down-converter, such as a rare-earth organometallic complex. The down-converter may be present in an amount of at least 0.0001 wt % based on the total weight of the encapsulant film. Further layers of a multilayer encapsulant film may or may not include a down-converter. Preferably, a multilayer encapsulant film contains at least one layer with at least one down-converter and at least one layer without a down-converter. Such multilayer down-converting films may be used in an electronic device, such as a PV module.
