Nanomaterial Applications in Solar Cell Encapsulation

Colloidal quantum dot photodetectors that achieve air stability through novel encapsulation structures. The photodetectors incorporate thin films of colloidal quantum dots on integrated circuits, with a sealing layer of controlled thickness (0.5 nm to 500 nm) between the quantum dots and the circuitry. This encapsulation enables hermetic sealing and prevents air exposure while maintaining quantum dot integrity. The sealing layer can be formed using atomic layer deposition (ALD) or other surface modification techniques, allowing precise control over thickness and properties. The photodetectors can operate across 250 nm to 2400 nm spectral ranges, including X-ray detection capabilities.

A coating-encapsulated thin-film solar cell that enables mass production of solar cells with improved durability and performance. The cell features a multilayer structure comprising a solar cell layer, a light scattering layer, and a paint encapsulation layer, all encapsulated by a thin film. The solar cell layer, light scattering layer, and paint encapsulation layer are arranged sequentially from top to bottom. The paint encapsulation layer provides enhanced weather resistance and aging resistance compared to traditional encapsulation methods. The coating-encapsulation architecture enables the use of a single production process for both the solar cell and encapsulation layers, significantly reducing production complexity and costs.

Enhanced encapsulant for photovoltaic modules that prevents degradation through controlled ion permeability. The encapsulant composition combines a conventional EVA copolymer with an enhanced anti-particle delivery copolymer (ANPC) that selectively prevents ion migration to the solar cell surface. This dual-component approach ensures the encapsulant maintains its protective properties while maintaining the solar cell's integrity.

Roll of solar cell packaging material film for photovoltaic modules that enhances adhesion through a moisture-controlled bobbin. The film, wound to 500mm to 1500mm diameter, contains a moisture level of 1000 ppm or less, specifically 750 ppm or less. This controlled moisture level prevents degradation of the film's adhesion properties, particularly when applying laminating compounds containing silane groups. The film's unique moisture profile enables improved adhesion during lamination, particularly for photovoltaic modules with encapsulated solar cells.
