Project description
Powering the future of light-based tech
Laser diodes are at the core of future technologies such as 6G communications and the Internet of Things, but creating efficient, high-power devices is challenging. With support from the Marie Skłodowska-Curie Actions programme, the HePeQul project aims to develop perovskite nanocrystal LEDs (PeLEDs), a solution-processable, tunable laser solution. The project endeavours to address major challenges, such as Auger recombination, heat build-up, and high-current operation, by engineering high-quality nanocrystals, optimising device architecture, and introducing state-of-the-art thermal management. Breakthroughs by HePeQul would enable PeLEDs to unlock unrivalled power and efficiency, opening the way for future lasers, displays, and lighting. This would help consolidate Europe's leadership in optoelectronics while fuelling economic growth through new materials and devices.
Objective
Laser diodes are pivotal for the Internet of Things (IoT), and forthcoming 6G communication by enabling efficient data transmission, low power consumption, and integration into photonic circuits. Perovskite nanocrystals-based LEDs (PeLEDs) offer a promising platform for solution-processable laser diodes with their tunable emission properties and high gain coefficients. The most critical step toward achieving Perovskite laser diodes is the development of high-power efficient PeLEDs capable of operating at the high current densities (j) required for lasing threshold. Despite recent advancements in PeLED efficiency, the key challenge remains: engineering high-power PeLEDs that must overcome the severe Auger recombination and excessive heat generation.
In this HePeQul project, I aim to develop high-power efficient PeLEDs by focusing on three main objectives: (1) developing high-quality PeQDs with suppressed Auger recombination and enhanced photoluminescence (PLQY>90%) by controlling nanocrystal nucleation growth processes and implementing surface modification strategies, (2) optimizing device architectures and transport layers to achieve efficient and balanced charge injection (EQE > 20%), and (3) Integrating advanced thermal management techniques, incorporating current-focusing patterns with pulse-mode driving, to enable PeLEDs to sustain high current densities (j>100 A cm⁻²). HePeQul will not only push the boundaries of current PeLED technology but also provide a foundation for next-generation high-performance optoelectronic devices, with potential applications in displays, lighting, and laser technologies. The project will also equip the fellow with interdisciplinary knowledge and skills. Successful implementation of HePeQul will promote the host organization's international competitiveness in PeLED and laser filed. Additionally, the commercialization of newly developed QD materials and PeLED products will contribute to economic growth and job creation in Europe.
