Design of new semiconductive materials

The production and storage of sustainable energy are among the main challenges of the 21st century. A promising alternative to produce green energy is solar photovoltaics or photocatalytic production of solar fuels, as both technologies use the sun as power source. In order to develop these technologies, it is necessary to design new efficient semiconductor materials. 

Crystalline coordination polymers (CPs) are a really promising type of materials for these applications. These hybrid solids are built up from an organic molecule coordinated to an inorganic unit (formed by metal ions). The great interest of these materials comes from their large chemical and structural variety, allowing to finely tune their properties.

In collaboration with Dr. Hermenegildo Garcia’s group (Universidad Politécnica de Valencia - Instituto de Tecnología Química, Valencia), a new semiconductor CP (denoted IEF-3 from IMDEA Energy Framework) was synthesized based on the non-toxic bismuth and the optically active squarate ligand. The IEF-3 material showed high thermal stability and exceptional chemical robustness under industrially relevant aggressive media, as well as a good photoelectronic response. This new material opens new perspectives in the photocatalytic and photovoltaic technology development
