Biogenic Solar Thermoelectric Conversion – BiSTeC

Project description

Optimising properties of composite phase change materials for solar thermoelectric conversion

Capable of harnessing both light and heat, solar thermo-electric generators (STEGs) are a promising technology for renewable energy generation. Biogenic polymers like cellulose-based composite phase change materials (PCMs) can improve energy storage and heat transfer. However, limitations such as low absorption, thermal conductivity and stability inhibit wider use. Supported by the Marie Skłodowska-Curie Actions programme, the BiSTeC project aims to design novel cellulose-based PCMs with enhanced absorption and thermal conductivity. To do so, PCMs will be integrated with fluorescent proteins, to increase both solar energy absorption and photo-induced heat generation, and nanocarbon additives, to improve heat transfer. The synergic effect of cellulose, fluorescent proteins and nanocarbons is expected to improve the stability and performance of PCM-based STEGs.

Objective

Advances in green energy materials and technologies are mandated by low-carbon energy policies. Clean energy harvesting, conversion, and storage from the sun and waste heat is viewed as a major player to tackle environmental issues and energy shortages. A solar thermoelectric generator (STEG) collects solar energy & converts it into electricity using the principles of the Seebeck effect. Among the biogenic polymers applied to STEG, cellulose-based composite phase change materials (PCM) stand out since the 3Ddirectional cellulose-based composite structure provides ideal energy storage and improves heat transfer pathways. However, they still feature issues related to the low absorption coefficient, limited thermal conductivity, and low self-stability (storage and mechanical stress). Design of BiSTeC promises enhanced cellulose-based PCMs merging i) fluorescent proteins (FPs) to simultaneously enhance solar energy absorption and photo-induced heat generation, ii) nano-carbon additives to enhance heat transport, and iii) Synergic effect of cellulose, FPs and nanocarbon boost output stable performance of PCM based STEG.
My expertise in the synthesis and enhancement of thermal properties of nanocomposite PCM and the host supervisor's expertise (Prof. Costa at the Technical University of Munich – TUM) on fluorescent protein (FP)-polymer coatings for photon-manipulation could provide an innovative twist in the field (design of efficient biogenic PCM based BiSTeC devices).
