Energy Harvesting and Storage with a High Voltage Organic Inorganic Photo‐Battery for Internet of Things Applications

“…Organic solar battery with high operating voltage using a multi‐junction organic solar cell and an organic redox‐polymer‐based battery). [ 39 ] The battery is based on NMC 622 as active cathode material, uses lithium metal as counter electrode and a LiPF 6 based electrolyte solution (for more details see experimental). The NMC electrode and the p‐contact of the OSC are stacked on top of each other and shorted by design and therefore make up one electrode, which we call electrode 2.…”

“…Organic Solar Cell Fabrication: All solar cells were fabricated following the same procedure as detailed in our previous work, [39] in the so-called inverted architecture, i.e., light enters the device through the electron contact, onto 25 Â 25 mm 2 large ITO-covered glass slides (VISIONTEK SYSTEMS LTD, R sheet = 15 Ω sq À1 ). Prior to fabrication, the substrates were cleaned by sequential dipping in ultrasonic baths with acetone, isopropanol, and water, twice in each solvent for 5 min, followed by drying with a nitrogen gun.…”

Unlocking twofold oxidation in phenothiazine polymers for application in symmetric all-organic anionic batteries

“…2,3 In contrast, batteries in which the electrode materials are organic in nature do not rely on critical resources, while also being easier to recycle, which makes them a much more environmentally friendly alternative. Even more importantly, organic batteries offer unique advantages in terms of their ability to have their properties fine-tuned by structural design to achieve superior features such as fast charging rate performance, 4 adaptability to special applications 5,6 or to tailor their redox potentials. 7,8 The latter cannot only be exploited to develop a large variety of either positive or negative electrode materials, but careful selection of the organic moieties in the active material(s) has also enabled researchers to establish battery cells based on two organic electrodes, so-called 'all-organic' full-cells.…”

These all-organic batteries can generally be conceived in three different configurations depending on the active materials .…”
