Light cured networks containing metal organic frameworks as efficient and durable polymer electrolytes for dye-sensitized solar cells

We describe the preparation of a polymer composite containing a Mg-based metal-organic framework (MOF) through a rapid and environmentally friendly UV-induced free-radical process. The composite is used as an electrolyte for quasi-solid dye-sensitized solar cells (DSSCs). Notable solar energy conversion efficiencies were obtained (eta = 4.8%), together with an outstanding long-term durability. Besides being an effective candidate for the enhancement of DSSC performance, this first ever MOF-based polymeric composite proves to be potentially exploitable for other applications, e.g. in the field of supported catalysis.
