Накратко на български

Метално-халидни перовскити без олово се анализират за превръщане на отпадната топлина в електричество. Това помага за създаването на по-екологични технологии за събиране на енергия и подобрява стабилността на материалите.

Thermoelectricity in metal-organic perovskites: recycling waste energy heat as electricity

The project focuses on metal halide perovskites, with particular attention to lead-free compounds: a promising eco-friendly alternative for energy harvesting technologies, particularly in solar cells. Metal halide perovskites exhibit polymorphism with different phases coexisting at room temperature. The research delves into the thermodynamic stability between different structures, utilizing first-principles thermodynamics and exploring phase transitions. This research addresses the broader issue of sustainable and efficient energy solutions, emphasizing the importance of metal halide perovskites in achieving these goals. The overall objective is to understand and improve these materials' mechanical stability and practical deployment, contributing to the advancement of eco-friendly energy technologies, analyzing their thermal properties for potential application as thermoelectric devices.

Цел на проекта

Thermoelectric materials convert thermal and electrical energy, and performant thermoelectric devices could be used to recover waste heat in manufacturing, cogeneration, and heavy transportation - reducing both energy requirements and greenhouse gases' footprint.Solid-state cooldown would also change refrigeration technologies, in both efficiency and maintenance. Broadly speaking, a materials' breakthrough in thermoelectrics would have an impact on energy efficiency similar to nitride LEDs for lightning technologies.Optimal thermoelectrics need to balance the contrasting requirements of good electrical conductivity and low thermal conductivity; nowadays the best bulk thermoelectric approaching the desired efficiency is SnSe. However, large-scale production is too expensive, and applications remain limited to niche markets.The goal of this project is to find efficient thermoelectrics in the class of metal-organic single and double halide perovskites.These are intensely studied for their photovoltaic efficiency, thanks also to their good electrical properties; they can be manufactured inexpensively at scale; and their lattice vibrations are very anharmonic and tunable, allowing to engineer low thermal conductivity.Since the overall number of possible compounds is above 500, there is wide chemical tunability of their properties. However, due to both theoretical and experimental difficulties, thermoelectric efficiency has been investigated only in very few compounds. Thanks to the unique capabilities I have developed during my PhD to study from first-principles materials with very large anharmonic distortions, I will investigate the full chemical space of these perovskites in the quest for the most efficient thermoelectric. Success in the project would bring major advantages to the industrial and economic EU ecosystem, but will also cement my leadership in characterizing and designing electrical and thermal properties of far from equilibrium materials.
