Researchers from the University of La Rioja, the University of Alicante and the Madrid Institute for Advanced Studies of Materials (IMDEA Materials) have achieved a record in energy efficiency with solar cells based on titanium oxide, as an alternative to conventional silicon-based cells.
University of La Rioja and University of Alicante researchers have developed and patented the technology that allows them to prepare active titanium oxides under visible light for application in photocatalysis and solar cells.
With the support of researchers from the Madrid Institute for Advanced Studies (IMDEA Materials), these materials have been integrated into solar cell electrodes that contain light-sensitive compounds and whose electrodes are prepared by low-temperature thermal treatment (low solar cells). temperature, lt-DSSC).
The arrangement of a layer of the new hybrid material on an electrode with a mixture of commercial titania P25 Degussa and titania nanoparticles has achieved an efficiency of 8.75%, the highest obtained to date with this type of solar cells. Only 6.6% efficiency levels had been achieved so far.
This advance represents an alternative to traditional solar cells based on silicon due to its lower cost, greater ease of processing and recycling, as well as its higher versatility.
These new cells respond to the need to replace glass substrates with other flexible (plastic) lightweight, which can be folded, are printable and adaptable to any surface.
In this sense, they could work as small-scale power generation units for applications both inside buildings (electronic devices, lighting, etc.) and outside: car roofs, roof tiles of a building or integrated into clothes to supply power to portable electronic devices, among others.
As for the people and research groups and centres involved in this project, they are as follows: on the one hand, the Organometallic Molecular Materials Group, from University of La Rioja (UR) with Elena Lalinde and Jesús Berenguer, the Molecular Nanotechnology Laboratory, from the University of Alicante (UA) with Javier García Martínez , Marisa Rico Santacruz and Elena Serrano Torregrosa and, on the other, the Madrid Institute for Advanced Studies of Materials (IMDEA Materials), with Rubén D. Costa.
The progress of this work will be published soon by the prestigious scientific journal Advanced Energy Materials.
