There has recently been a growing interest in dye sensitized solar cells (DSSCs) based on ruthenium metal, but due to the scarcity and high price of ruthenium, design of better and cheaper light adsorbent dyes based on more abundant metal ions is one of the key issues for future development of the DSSCs. Using density functional theory (DFT) and time-dependent DFT we have studied the properties of new and abundant metal ion-based polypyridyl dyes for p-type DSSCs and compared with ruthenium and other scarce metal ions. Molecular geometries, electronic structures, and optical absorption spectra have been calculated using an implicit solvent corresponding to acetonitrile. The calculated fair light harvesting efficiency, high hole injection efficiency and Gibbs free energy for the hole injection and longer excited state lifetime (important for reflecting the efficiency of solar cells) for the new abundant metal ions (V3+ and Cr2+) based dyes could provide promising sensitizers for efficient next generation DSSC's for p-SC.

Metal-organic framework materials (MOFs) offer the opportunity to exploit open-metal sites having well-defined coordination environments, one of the key features of which is open-metal oxidation state. MIL-100(Cr) is a prototypical MOF in this regard, with M2+ sites offering the potential for breakthroughs not only in the area of selective gas adsorption but also acid and redox catalysis. We report herein, for the first time, the use of hydroxyl anions in accessing the theoretical maximum density of MIL-100 Cr2+ sites. We show, using five complementary characterization techniques, that the use of hydroxyl-endowed MIL-100, unlike the fluoride-containing analogue used extensively in the literature, enables creation of one Cr2+ site per node. The results point to anion identity being a key synthetic choice, the judicious use of which could enable control over open-metal oxidation state in MOF broadly.
