“…Particularly, protonic (ionic) and mixed conductors can be integrated in logic circuits to mimic, register and stimulate biological functionalities. 45,46 Beside converting biochemical (ionic) into electronic signals, 47 they can be active components in bioprotonic field-effect transistors, 48 lightemitting diodes 11 and switching memory devices. 49,50 Therefore, understanding the role and the impact of mixed transport on the mesoscopic properties of bio-sourced materials is the underpinning to design and develop high performance (bio) electronic devices.…”

“…Recently, Langer's group designed and developed the first lightemitting diode (PLED) based on protonic conducting materials. 11 The active layers of PLEDs were assembled interfacing hydrated proton donor-proton acceptor (H + /OH -) Please do not adjust margins Please do not adjust margins conductors between Pt electrodes. Dowex-50 (Dx50) and two types of sulfonated crosslinked polystyrenes (SPS) were used as proton donor layers and Dowex-1 (Dx1) as proton acceptor layers.…”

“…This leads to higher intensity of the light emission with maximum at 750 nm, assigned to protonic system, and lowering the emission at ~850 nm observed for dry material, when mainly the electrons are excited. The provided electrical energy excites the hydrogen bonding system in water up to the energy levels of combination vibrations and overtones 4 . The presence of water is crucial.…”

“…On the other hand, we have discovered emission in the entire range of UV-VIS-NIR due to the excitation of protons in the protonic analog of the p-n junction (protonic LED 4 ), formed in water as a protonic semiconductor, appropriately doped 5,6 . Now, we describe the system (polyaniline doped with ptoluenesulfonic acid, PANI/PTSA), where electrons and protons are excited when electrically powered, emitting the light in different range, on a competitive way.…”

resources involves the conversion of sunlight energy directly to electricity using photovoltaic technologies. In this regard, extensive research efforts are being been focused on the development of new photovoltaic devices, including organic solar cells (OSCs), perovskite solar cells (PVSCs), and organic light-emitting diodes (OLEDs). [1,2] Such devices benefit from the numerous advantages of organic compounds, which can be chemically modified to achieve the desired device performance. [3][4][5][6] With decades of study, organic semiconductors now exhibit outstanding electronic and structural properties that has led to the fabrication of innovative organic devices with impressive output characteristics, including high field-effect mobility (10 cm 2 V −1 s −1 ) in organic field-effect transistors (OFETs), and high efficiencies of 17% in OSCs and 25% in PVSCs. [7][8][9][10][11][12][13][14][15] Furthermore, the inexpensive access of organic materials that can be processed through low-cost solution processing methods is widely attractive for practical applications that require the light-weight devices to be flexible and transparent. [16] The performance of organic electronic devices depends primarily on the properties of the active layer and electrodes, but also relies heavily on the properties of the various device interfaces. In recent years, a remarkable advancement in device Compared to their inorganic counterparts, organic optoelectronic devices receive considerable attention due to their lower cost, mechanical flexibility, bandgap engineering, and solution processability. In particular, achieving sustainability in solar cells and light emitting devices is an important milestone in the development of green electronics. This has facilitated a close collaboration between different technological fields, opening new ways for low-cost production and application of biomaterials. Recently, biomass materials, mainly derived from plants, animals and microorganisms, have emerged as effective candidates to modify the interfacial properties, and thus enhance the performance, lifetime, and stability of organic solar cells (OSCs), perovskite solar cells (PVSCs), and organic light-emitting diodes (OLEDs). Compared to the commonly used synthetic interfacial materials, the use of biomass interlayer materials (BIMs) is still in its embryonic stages; however, their nontoxicity, biorelevance, sustainability, special proton conductivity, and rich functional groups are stimulating researchers around the globe to fabricate novel devices with improved efficiency. Herein, a comprehensive review of BIMs and their importance in next-generation optoelectronic devices is provided. A welltargeted comparison between the electrical and physical properties of different BIMs is provided, and how such characteristics improve the performance of three key optoelectronic devices: OSCs, PVSCs and OLEDs, is discussed.

Electrically induced light emission from proton-conducting materials. Protonic light-emitting diodes

Abstract: Water doped with H+ and HO− enables the formation of a protonic p–n junction, which works similarly to a typical, electron-based p–n junction, including light emission when electrically powered. Polymers provide mechanical stability.
