Everlight Chemical is a materials supplier known for its Eversolar® encapsulant portfolio, used by research groups and manufacturers working on perovskite and other emerging thin-film solar technologies. We interviewed Yun-Chang (Gordon) Chao, Photovoltaic Materials Manager in the Sales Department at Everlight Europe B.V., who walked us through the company's encapsulation materials, its academic collaborations, its take on where the perovskite industry stands today, and its plans for the future! Perovskite Connect 2026. Everlight Chemical will also be speaking at Perovskite Connect 2026.

Please start by describing Everlight's current activities and focus areas within the perovskite field
Everlight Chemical has been developing encapsulation materials for emerging photovoltaic technologies since the dye-sensitized solar cell, or DSSC, era. Today, our main focus includes practical encapsulation solutions for perovskite solar cells, perovskite-silicon tandems, all-perovskite tandems, organic photovoltaics, and other sensitive thin-film devices.
Our work goes beyond supplying materials. We support academic and industrial partners with material selection, encapsulation structure design, coating method evaluation and long-term reliability testing.
We adapt our materials to different device structures and production methods, including dispensing, slot-die coating, screen printing and others. Our goal is to help partners close the gap between high-performing laboratory cells and reliable, manufacturable products.
We believe encapsulation should be considered from the beginning of device and process development, rather than treated only as the final packaging step.
