HeteroPlates project addresses a critical issue in the materials science domain: the quest for an ideal material that can redefine light-matter interaction for energy conversion technologies. Despite the promising high efficiency and processing ease of metal halide perovskites, their vulnerability lies in their stability, particularly when forming interfaces with other materials. This instability is a significant barrier, hindering the realization of their full potential in photovoltaic and electro-optic applications.
Importance: In a world with an escalating demand for energy, society stands to benefit immensely from breakthroughs in energy conversion and storage. Materials that can heal themselves and maintain stability over time are not just a scientific curiosity—they represent the next leap in extending the lifespan of electronics, reducing electronic waste, and enabling more sustainable energy sources. Self-repairing capabilities within electronic materials could revolutionize industries, leading to longer-lasting devices and more resilient systems, mitigating the environmental impact of our growing energy needs.
Objectives:
To pioneer the development of next-generation heterostructures, "HeteroPlates" is designed to address the urgent need for innovative materials that can meet the global demand for energy. To transcend current technological capabilities with perovskite heterostructures, we outline the project objectives:
Exploit the high conversion efficiency and ease of processing of metal halide perovskites while overcoming their stability challenges to improve long-term device performance; this is based on observation of enhanced stability and efficiency in perovskite plates.
Develop colloidal synthesis and processes to make perovskite heterostructures. We will select interfaces significantly influencing the electronic structure, device functionality, efficiency, and stability.
Employ Bottom-up Synthesis for colloidal perovskites. We will utilize the self-organizing properties of colloidal 2D nanoplates to assemble them into controlled heterostructures, enhancing collective effects.
Develop and apply novel characterization methods to achieve unprecedented imaging resolution and insight into the heterostructures at the nanoscale. Aiming for ultra-high spatial resolution with the ability to acquire spectral information.
Translate the findings from the study of colloidal heterostructures into practical applications by creating devices that showcase new functionalities and pave the way for future technology.
Through these objectives, HeteroPlates seeks to lead a paradigm shift in material science, offering sustainable solutions to the energy sector and setting a precedent for future innovations in the field of low dimensional materials.
