Flexible perovskite LED with CNT electrodes

Solarno Inc., Dallas, TX and Texas State University, San Marcos, TX will develop a novel roll-to-roll compatible, cost-effective method to manufacture high-efficiency, ultra-light-weight, flexible LED lighting panels based on hybrid organohalide lead perovskite light emitters and carbon nanotube transparent electrodes. We will fabricate the panels on aluminized polymer films using industry proven and scalable slot die coating process. CNT films will be self-laminated on top of the device stack in vacuum-free, cost-effective, and roll-to-roll compatible process. Solarno specializes in roll-to-roll manufacturing of self-supporting CNT films. In this project, we will utilize spray-coated Ag nanowires to improve CNT electrodes resistivity and reach target of 10 Ohm/sq, and optical transmission T=90%. Solarno will work closely with Texas State University to optimize the hybrid organohalide lead perovskite LED devices and characterize perovskite films deposited on various aluminized plastic substrates. During 6 month option period Solarno and TXST will measure lifetime of devices fabricated and investigate scalability and producibility of the fabricated prototype devices.
