Periodic Reporting for period 3 - CapTherPV (Integration of Capacitor, Thermoelectric and PhotoVoltaic thin films for efficient energy conversion and storage )

Teaser

Summary

This projects aims to developed a device able to convert energy from light and thermal gradients available everywhere into electricity and the corresponding storage in a single device. This will bring flexibility to power supply autonomous energy sources at a low cost.

The innovation proposed relies on ground-breaking concepts that include:
1) thermoelectric elements based on thin film (TE-TF) oxides;
2) plasmonic nanoparticles for up conversion of near infrared radiation to visible emission in solar cells;
3) development of graphene supercapacitors;
4) integration and optimization of all components in a single CapTherPV device.

Work performed

In the period covered by this report, thermoelectric thin films have been developed as well nanoparticles with specific with down conversion of radiation spectra in the UV to visible range and up conversion from NIR to visible. Super capacitors made of graphene layers have been also investigated being achieved good capacity and charge and discharge stable cycles.

Final results

New thermoelectric materials, hybrid solar cells and energy storage devices are expected to be developed during the first three years of the project. After, the holist integration of the solar and thermal energy harvesting and its storage will demonstrate a new concept of energy conversion and supply. This concept was not yet implemented and will bring integrated approaches to solve separated solutions obtained so far.
