Everlight Chemical Partners with Taiwan Perovskite Technology to Develop UV Encapsulation Solutions for Perovskite Modules

Industry Insights & News

Everlight Chemical and Taiwan Perovskite Technology Corp. (TPSC) have partnered to integrate Eversolar® series of UV-curable encapsulation materials into perovskite module development. Combining their strengths in materials R&D, cell processing, and module validation, the two companies are conducting encapsulation testing on small-area cells via the Perovskite Hub / Tinderbox rapid material validation platform. This serves as the foundation for subsequent module design and product application evaluations. Co-developed demonstration samples will be exhibited at Energy Taiwan 2026 to showcase encapsulation progress to industry partners.

Joint Validation of Materials and Processes to Address Product Development Needs

As perovskite solar cells transition from laboratory components to commercial applications, encapsulation represents a crucial development phase. Beyond shielding cells from moisture and oxygen, encapsulation materials must be fully compatible with cell structures and processing conditions. Verifying smooth coating, lamination, curing, and post-encapsulation electrical stability requires rigorous testing on actual physical samples.

This collaboration combines Everlight Chemical’s material development expertise with TPSC’s cell processing and module validation capabilities, establishing a continuous feedback loop within a unified development workflow. Everlight Chemical supplies encapsulation materials and processing options, while TPSC provides feedback based on actual cell production, encapsulation integration, and testing—laying a solid foundation for future product development.

Fabrication of Showcase Samples Completed; Ongoing Reliability Evaluations

The partners have successfully integrated Eversolar® AB-302c UV-curable sealant with PET substrate for small-area perovskite cell encapsulation testing, producing physical demonstration samples. They have established a complete validation workflow covering dispensing/coating, PET lamination, UV curing, and electrical testing. Through continuous feedback across material trials, sample fabrication, and testing, both parties are analyzing the interplay between materials, encapsulation structures, and process parameters to refine future designs.

UV curing offers process flexibility for diverse and customized module designs by adapting seamlessly to dispensing, lamination, and exposure procedures. Both companies will continue evaluating performance metrics—including encapsulation integrity, interfacial adhesion, and electrical stability—alongside module-level testing to confirm moisture/oxygen barrier properties and long-term environmental reliability.

Data accumulated from small-scale samples will also serve as the baseline for evaluating automated integration across dispensing, coating, lamination, curing, and inspection. As module dimensions scale up toward pilot production, the partners will further validate large-area coating, illumination uniformity, and encapsulation stress to build robust manufacturing and reliability benchmarks.

Exploring IoT and Electronics Applications; Open Exchanges at Energy Taiwan

Driven by market demand, the partnership will explore applications in self-powered IoT devices, sensors, and consumer electronics, helping downstream application partners evaluate the integration feasibility of these encapsulation solutions through comprehensive material and module testing.

TPSC and Everlight Chemical will continue sharing progress in material development and module validation. Leveraging the Perovskite Hub platform, they aim to connect material suppliers, equipment vendors, system integrators, and brand partners to jointly accelerate the commercialization of perovskite technology.

The co-developed perovskite encapsulation samples will be showcased at Energy Taiwan. Industry partners are cordially invited to visit TPSC’s booth (J0717, Hall 1, Taipei Nangang Exhibition Center) from October 14 to 16, 2026, to explore UV encapsulation advances and discuss potential collaborations in material matching, customized modules, encapsulation processes, automation integration, and application testing.
