Group Leader: Mónica Lira-Cantú

Main Research Lines

  • Photovoltaics: Next-generation thin-film, organic, hybrid, dye-sensitised, halide perovskite and all-oxide solar cells
  • Synthesis of nanomaterials by low-cost, low-temperature and green solution processing methods
  • Solution processing methods for the fabrication of solar cells and printed electronics
  • Degradation studies of the stability of solar cells following ISOS protocols
  • Semiconductor oxides for energy and ICT applications by solution processing fabrication
  • Self-driven energy devices

The Nanostructured Materials for Photovoltaic Energy Group has several key objectives, all of them related to the development of highly-efficient, highly-stable and low-cost solution processable photovoltaic and optoelectronic devices.

A major goal is the synthesis of nanostructured materials, especially those involving transition metal oxides (TMOs) and graphene, via the application of low-cost and solution processing methods. TMOs have many possible applications as main active materials or barrier layers, though they also find applications as materials for external light management. The application of low-temperature synthesis methods (sol-gel, hydrothermal, SILAR, among many others) permits tuning and control of the properties of the final device. These oxides are being applied in our group as nanostructured materials (nanorods, nanowires, nanotrees, core-shell, etc.) and dense thin films in the various next-generation solar cells offering excellent performance in term of efficiency and lifetime. The functionalisation of these oxide surfaces is now carried out in our group by anchoring self-assembled monolayers with selected anchoring groups to interact simultaneously with the oxide and the active light harvesting material.  

The stability and lifetime of optoelectronic devices, especially organic and perovskite solar cells, is a major limitation for these technologies. An important contribution of the group is the study and characterisation of solar cell stability following degradation and characterisation protocols. Prof. Lira-Cantu coordinates a COST Action with a consortium of more than 470 members, among them 60 internationally-recognised research laboratories and 22 companies from 35 countries. StableNextSol, as the project is known, is related to the stability of organic and perovskite solar cells. Its goal is to take advantage of the multiple characterisation techniques available through the different partners to elucidate the degradation mechanism of these devices and propose disruptive solutions towards highly stable organic solar cells.

Other interests include the development of self-driven energy devices for ICT and bio-related applications.
