Company Profile:
The Complutense University of Madrid (UCM) is the oldest university in Spain. Its educational and research activities cover almost all knowledge fields: Humanities, Social Experimental and Health Sciences. Research is a prior activity into this university being of high standard as can be shown by its participation in different national and international calls.
The university also has specialized Research Institutes for scientific and technical research providing technological advice.

OTRI-UCM: Research Knowledge Transfer Office

What we offer:
The main objectives of the Research Knowledge Transfer Office are: the creation, updating and fostering of the Complutense University's scientific and technological research portfolio; to identify both the transferable results generated by University researchers and the potential R&D requirements of companies to establish contractual relationships between the University and business; to advise researchers on the formulation of research contracts and R&D project proposals and on writing and applying for patents, both at national and international level; to advise businesses on how to find solutions for their technological needs and to offer information on financial assistance for the creation of R&D projects in Spain and Europe.

New intermediate band solar cell for photovoltaic power generation

What we offer:
A new intermediate band (IB) solar cell has been designed at UCM wherein all three materials, the intermediate band, the p-type semiconductor n-type semiconductor are arranged in a lateral configuration on a given substrate, forming a heterogeneous surface layer.
If the (IB) material is connected to an n-type semiconductor and another type p, contacting only the latter from the outside, IB material remains isolated and it is not hidden by any of the other two issuers. Thus loss of voltage is avoided and the efficiency of the solar cell increase.

With this new design the three materials can be manufactured simultaneously or in desired ordered phases, instead of the traditional structure of layers that arranges the production of the materials.

This kind of solar cell can work with back contacts so its both sides can face the sunlight for power generation.

What we are looking for:
The R&D group looks for collaborating with companies from photovoltaic industry interested in applying this technology in their products, adding a new solution in its catalog.
They are also looking for partners for public funding for further development.

Collaboration sought:
  • Technical cooperation
  • Commercial cooperation
  • R&D cooperation
