“…[83] On the other hand, the performances obtained for the NiO/Co system are also significant compared to those reported in recent works dealing with the investigation of Li-doped NiO in p-DSSC [84] or the use of novel carbazole-based push-pull organic dyes. [85] Indeed, the interfacial photo-induced charge separated state is rather long-lived. Cobalt redox shuttles can…”

This work explores the potentiality of Mo 6 clusters as new inorganic sensitizers with amphoteric properties for photoelectronic applications being non-toxic and stable. It reports on the design of photoelectrodes by electrophoretic deposition (EPD) of molybdenum octahedral metal cluster iodide (CMI) onto mesoporous TiO 2 and NiO layers before being deposited on FTO (i. e. CMI@TSO@FTO, TSO = TiO 2 or NiO). Indeed, the low-cost, lowwaste and industrially scalable EPD method has allowed for the achievement of transparent,

“…An early work by Preat et al focuses on computing the electronic excitation and electron injection processes of P1 and derived dyes using as model for NiO a single Ni atom capped by a hydroxyl group to ensure the overall neutrality of the system (Preat et al, 2011). Regarding periodic-slab and spin-polarized DFT calculations, taking into account also the intrinsic magnetism of NiO, only few recent computational studies have addressed the interaction of dye/anchoring groups with the most stable surface of NiO, i.e., the (001) (Muñoz-García and Pavone, 2015; Kontkanen et al, 2016; Wykes et al, 2016; Carella et al, 2018). Wykes et al (2016) have studied formic and benzoic acid (HCOOH and PhCOOH) as prototypes of the most commonly used carboxyl-based anchoring groups, as well as mono and dimer phenyl-silane [PhSi(OH) 3 ] anchoring candidates, due to the known capacity of alkoxysilanes to form Si-O-metal bonds.…”

Here we report the first theoretical characterization of the interface between the CuGaO 2 delafossite oxide and the carboxylic (–COOH) and phosphonic acid (–PO 3 H 2 ) anchoring groups. The promising use of delafossites as effective alternative to nickel oxide in p-type DSSC is still limited by practical difficulties in sensitizing the delafossite surface. Thus, this work provides atomistic insights on the structure and energetics of all the possible interactions between the anchoring functional groups and the CuGaO 2 surface species, including the effects of the Mg doping and of the solvent medium. Our results highlight the presence of a strong selectivity toward the monodentate binding mode on surface Ga atoms for both the carboxylic and phosphonic acid groups. Since the binding modes have a strong influence on the hole injection thermodynamics, these findings have direct implications for further development of delafossite based p-type DSSCs.

“…In this scenario, California could represent a case study, being a state historically launched towards a wide use of renewable energy sources, photovoltaics in particular [ 15 , 16 , 17 , 18 , 19 ]; the above-mentioned issues were highlighted some years ago [ 20 , 21 , 22 ]. In the chart shown in Figure 1 A, it is possible to appreciate the difference between the demand for electricity and the electric power produced by photovoltaic panels in the Californian grid, in a typical spring day and depending on the various years from 2012 to 2020 [ 23 , 24 ].…”

An Overview on Anodes for Magnesium Batteries: Challenges towards a Promising Storage Solution for Renewables

Magnesium-based batteries represent one of the successfully emerging electrochemical energy storage chemistries, mainly due to the high theoretical volumetric capacity of metallic magnesium (i.e., 3833 mAh cm−3 vs. 2046 mAh cm−3 for lithium), its low reduction potential (−2.37 V vs. SHE), abundance in the Earth’s crust (104 times higher than that of lithium) and dendrite-free behaviour when used as an anode during cycling. However, Mg deposition and dissolution processes in polar organic electrolytes lead to the formation of a passivation film bearing an insulating effect towards Mg2+ ions. Several strategies to overcome this drawback have been recently proposed, keeping as a main goal that of reducing the formation of such passivation layers and improving the magnesium-related kinetics. This manuscript offers a literature analysis on this topic, starting with a rapid overview on magnesium batteries as a feasible strategy for storing electricity coming from renewables, and then addressing the most relevant outcomes in the field of anodic materials (i.e., metallic magnesium, bismuth-, titanium- and tin-based electrodes, biphasic alloys, nanostructured metal oxides, boron clusters, graphene-based electrodes, etc.).
