Encapsulant Film Composition and Encapsulant Film Including the Same

Resumen de: US2025197573A1

The encapsulant film composition includes an ethylene/alpha-olefin copolymer and porous silica and has excellent compatibility with a crosslinking additive. The encapsulant film composition has a ratio of an Si—O band integral value to a C—H band integral value of from 3 to 70. When an encapsulant film is produced using the encapsulant film composition, the impregnation time of an ethylene/alpha-olefin copolymer is reduced so that the economic viability of a process of producing an encapsulant film can be improved. Moreover, by delaying the transfer of the crosslinking agent, it is possible to suppress a slip phenomenon of the encapsulant film. The present disclosure also relates to a solar cell module.

SOLAR MODULE RECYLING THROUGH ARTIFICIAL INTELLIGENCE

Resumen de: US2025202425A1

Embodiments employ Artificial Intelligence (AI) techniques to collect and analyze data associated with material input to a solar module recycling system, including e.g., AI model(s) and/or the recycling and recapture of the component materials.

Analysis of module recycling using the AI techniques may consider one or more of the following: module model; module manufacturer; module type (e.g., c-Si versus CdTe); power rating; module history; module label information; predicted/actual market prices; others. An outcome of AI analysis can offer estimates of resultant effect(s) upon speed and efficiency, by which materials travel through the recycling system. One possible benefit is the ability to rapidly optimize system parameters, providing high solar module throughput in the recycling system over time.
