RESHAPE · Revolutionizing Sustainable Architecture with High-Efficiency Geopolymer Thermoelectric Modules for Energy Harvesting

Thermoelectric (TE) technology, which can convert thermal energy into electrical power, represents a crucial clean energy innovation. When integrated into the field of architecture, it holds the potential to transform buildings from passive energy consumers into active energy generators. Furthermore, it can serve as an effective strategy to mitigate the rising urban heat island effect and soaring summer temperatures, which are increasingly prevalent in the European Union (EU). In recent years, TE cement composites have garnered significant attention due to their robustness and cost-effectiveness compared to commercial TE modules. However, the thermoelectric performance of TE cement composites typically falls significantly below the requirements for practical applications. This project aims to lead the development of high-efficiency geopolymer TE modules for energy harvesting, thereby advancing the EU's progress towards achieving nearly zero-energy buildings. The proposed high-efficiency geopolymer TE module represents an innovative building material that can fulfill both structural (mechanical) and TE (energy harvesting) roles. The mechanical and thermoelectric properties of these geopolymer modules will be enhanced through the addition of various additives. Subsequently, the project will analyze the reversibility/cyclability aging and mechanical durability of geopolymer TE modules to further enhance their functionality and applicability. Additionally, a comprehensive thermo-electro-chemo numerical model will be employed and validated using data obtained from microstructural assessments of aging geopolymer TE modules.
