The aim of this project consists in gathering, in a single substrate, solar cells with up-conversion nanoparticles, thermoelectrics and graphene super-capacitor, all made of thin films. These three main components will be developed separately and integrated sequentially. The innovation proposed is not limited to the integration of components, but rely in ground-breaking concepts:

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. graphene super-capacitors;
4. integration and optimization of all components in a single CapTherPV device.
