“…A major difference is the semicircle in the high‐frequency range, which corresponds to the charge‐transfer resistance ( R CT ). The R CT caused by the Faradaic reactions is a result of the frequency dependence of ion diffusion/transport in the electrolyte to electrode surface . Here, the R CT of P‐rGOA, rGO, and PEDOT:PSS electrodes are 238.2, 329.0, and 330.6 Ω, respectively.…”

A versatile composite aerogel is developed by introducing of PEDOT:PSS in reduced graphene oxide, resulting in an ultrathin aerogel film around 100 µm thick. Like a tape, the aerogel can tightly attach to smooth or rough substrate, and there forms a self‐healable and anti‐vibration energy storage electrode. With a Ti foil substrate, the electrode offers an electrochemical capacity of 190 mF cm−2 at 0.1 mA cm−2 working current density. It also exhibits 98.7% capacitance retention after 10 000 charge/discharge cycles, with almost negligible capacitance decline even after eight damaging/healing cycles or 4000 vibrating cycles. With symmetrical aerogel‐based electrodes, a smart electrochemical device is explored as a sensor for sensitively detecting space electric field strength, ranging from 1100 to 19 000 V m−1. Simulation results verify that the response current in the sensor comes from the internal recombination current in the electrochemical device, which originates from ion recombination near the electrode substrate in space electric field. Further, a validation sensor experiment is designed and realized with affiliated modules, successfully monitoring space electric field.

The cutting-edge photovoltaic cells are an indispensable part of the ongoing progress of earth-friendly plans for daily life energy consumption. However, the continuous electrical demand that extends to the night time requires a prior deployment of efficient real-time storage systems. In this regard, metal-air batteries have presented themselves as the most suitable candidates for solar energy storage, combining extra lightweight with higher power outputs and promises of longer life cycles. Scientific research over non-precious functional catalysts has always been the milestone and still contributing significantly to exploring new advanced materials and moderating the cost of both complementary technologies. Metal-organic frameworks (MOFs) derived functional materials have found their way to the application as storage and conversion materials, owing to their structural variety, porous advantages, as well as the tunability and high reactivity. In this review, we provide a detailed overview of the latest progress of MOF-based materials operating in metal-air batteries and photovoltaic cells.

“…Other approaches involved lead [234] and copper-based [235] materials. Zeng et al combined a 2D Pb-based MOF with Spiro-OMeTAD as innovative HTL in PSCs [234]. The authors evidenced a haloing orienting effect of the latter leading to a smoother interface with PSK, higher hydrophobicity and an upshifting of the energy level when compared to Spiro-O-MeTAD, leading to a 25% increase in PCE and a longer stability.…”

Application of Metal-Organic Frameworks and Covalent Organic Frameworks as (Photo)Active Material in Hybrid Photovoltaic Technologies

Metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) are two innovative classes of porous coordination polymers. MOFs are three-dimensional materials made up of secondary building blocks comprised of metal ions/clusters and organic ligands whereas COFs are 2D or 3D highly porous organic solids made up by light elements (i.e., H, B, C, N, O). Both MOFs and COFs, being highly conjugated scaffolds, are very promising as photoactive materials for applications in photocatalysis and artificial photosynthesis because of their tunable electronic properties, high surface area, remarkable light and thermal stability, easy and relative low-cost synthesis, and structural versatility. These properties make them perfectly suitable for photovoltaic application: throughout this review, we summarize recent advances in the employment of both MOFs and COFs in emerging photovoltaics, namely dye-sensitized solar cells (DSSCs) organic photovoltaic (OPV) and perovskite solar cells (PSCs). MOFs are successfully implemented in DSSCs as photoanodic material or solid-state sensitizers and in PSCs mainly as hole or electron transporting materials. An innovative paradigm, in which the porous conductive polymer acts as standing-alone sensitized photoanode, is exploited too. Conversely, COFs are mostly implemented as photoactive material or as hole transporting material in PSCs.
