Roll-to-Roll Printing of Perovskite Solar Cells on Flexible Corning Glass

February 20, 2020 by Paul Shepard

Energy Materials Corporation (EMC) announced the signing of a joint development agreement (JDA) with Corning Incorporated. Working together, the companies are focused on bringing low-cost, high-performance perovskite solar photovoltaic panels and products to the energy industry.

The JDA focuses both companies' respective industry leading capabilities using Corning's flexible Willow® Glass as the printing substrate in EMC's proprietary (patents pending) printing process.

Dr. Stephan DeLuca, EMC's CEO, said, "Today's solar panels require high efficiencies and long life. Corning® Willow® Glass greatly expands the process window for manufacturing high- performance perovskite solar modules using high-speed, roll-to-roll printing, while providing an encapsulation barrier that improves product life. We are excited to be working on an exclusive basis with the world's leading innovator of functional glass products."

Roll-to-roll processable flexible Willow Glass is a uniquely tailored substrate for printed perovskite-based photovoltaic panels because of thermo-mechanical stability, optical clarity, surface quality, and excellent barrier property," said Dr. Dipak Q. Chowdhury, division vice president and technology executive, Corning Technology Center Korea.

"The combination of high-throughput R2R process, and the superior material properties of Corning Willow Glass enables high-speed and high-performance photovoltaic cell manufacturing," concluded Chowdhury.
