The Photovoltaic Laboratory of the Micro and Nanotechnologies Group  (MNT-Solar) works in the development of emerging thin film photovoltaic materials for energy harvesting, with special emphasis in the synthesis and functionalization of inorganic chalcogenides and halides compounds. They are specialized in the “synthesis by physical vapor deposition” techniques (co-evaporation, sputtering, e-beam, thermal evaporation) of new chalcogenides, halides and mixed chalco-halides energy materials. They are also focused in the fabrication and characterization of solar cell devices onto different types of substrates (including glass, polymers, metal foils). Their research aims to develop more sustainable and efficient photovoltaic materials and cells for both indoors and outdoors.

Their current research topics are:

• Synthesis of chalcogenides, halides and mixed chalco-halides for energy harvesting applications using physical vapor deposition techniques.
• Research of emerging inorganic materials for photovoltaics.
• Development of highly selective contacts based on oxi-sulfides and organic molecules for solar cell devices.
• Fabrication and optoelectronic characterization of thin film solar cells.
• Solar cells design and theoretical modeling.
