“…Importantly, these cellulose and derivatives have some similar moieties with PEIE and MSAPBS, which can emerge as potential materials for the interface layer of OSC devices. Very recently, cellulose has been used as counter electrode for dye‐sensitized solar cells and flexible substrates for perovskite solar cells for green electronics by our group. Carboxymethyl cellulose sodium (CMC), one of the typical cellulose derivatives, can be prepared from rice straw and reed of agroforestry residues, and has been applied for different functions such as adhesive, stabilizer, and film former .…”

The research on organic solar cells (OSCs) has made an immense progress over the last one decade because OSCs possess multiple advantages, such as light-weight, efficient, economical and large-area fabrication. [1][2][3] To date, the power conversion efficiency (PCE) at the laboratory scale has reached up to ≈16% by employing novel interfacial and photoactive materials. [4] Prior to the importance of photoactive layer, interfacial layer also plays a vital role to fabricate high-performance OSC by reducing the energy barrier at the interface and improving charge transfer. [5,6] However, it is usually impossible for the conventional single interlayer materials to satisfy all the requirements. In this regard, it is highly desirable to develop novel interfacial materials with suitable modification for highly efficient OSCs.To develop effective cathode interfacial materials, interface barrier should be minimized with improved electron mobility. Generally, interface barrier originates directly from the mismatch of the energy levels between the active layer and electrodes. Therefore, the key is to design suitable interfacial materials which can significantly reduce the interface barrier between the electrodes and active layer. In the past decades, numerous attempts have been made and significant progresses have been achieved for the cathode interface modification of OSCs. For example, few metallic salts, including LiF, CsF, and Cs 2 CO 3 , [7][8][9] have been integrated into OSCs to modify the interface and the devices exhibited enhanced efficiencies. However, the electron transfer ability of these metallic salts is low and these layers are thickness sensitive (<1 nm), which restrict their application on large scale. In this regard, some organic materials are also introduced for the interface modification of OSCs. Generally, organic materials are synthesized easily with high electron mobility and tunable bandgap energy. Some of them (poly [(9,9-bis(3′-(N,N-dimethylamino)propyl)-2,7-fluorene)-alt-2,7-(9,9-dioctyfluorene)], polyethylenimine, and polyethylenimine ethoxylated (PEIE)) were found to be effective interface modifiers with matched performance of these devices, compared to the devices using conventional interlayer materials (Ca/Mg). [10,11] However, OSC devices. However, the limited resources, high-cost, and non-ecofriendly nature of petrochemical-based interface materials restrict their commercial applications. Here, a facile and effective approach to prepare cellulose and its derivatives as a cathode interface layer for OSCs with enhanced performance from rice straw of agroforestry residues is demonstrated. By employing this carboxymethyl cellulose sodium (CMC) into OSCs, a highly efficient inverted OSC is constructed, and a power conversion efficiency (PCE) of 12.01% is realized using poly[(2,6-(4,8-bis(5-(2-ethylhexyl)-thiophen-2-yl)-benzo[1,2-b:4,5-b′] dithiophene))-alt-(5,5-(1′,3′-di-2thienyl-5′,7-bis(2-ethylhexyl)benzo[1′,2′-c: 4′,5′-c′]dithiophene-4,8-dione): 3,9-bis(2-methylene -((3-(1, 1-dicyanomethylen...

“…material for the photoactive components in solar cells because of its good charge transport properties, e.g., high surface areas and superior transparency. [88,112,114,150,151] For example, Zhu et al [112] reported a transparent and biodegradable conductive electrode derived from bamboo cellulose for flexible perovskite solar cells. The power conversion efficiency (PCE) of the bamboo cellulose-based solar cell is 11.68%, which is the highest efficiency among the reported biomass-based perovskite solar cells.…”

The capability of devices in future ubiquitous networked wearable and implantable electronics to efficiently scavenge and store operational power from their working environment through sustainable pathways would enable viable self‐powering schemes in societally‐pervasive applications such as advanced healthcare and robotics. Triboelectric nanogenerators (TENGs) can efficiently harvest the ubiquitous mechanical energy for powering electronics and sensors. However, the majority of demonstrated TENG prototypes have been built with materials that are not biodegradable or biocompatible, which significantly hinders the application of TENGs for wearable and implantable technologies. In this review, the recent progress of the wearable and implantable triboelectric devices built with bio‐derived natural materials is summarized. The properties of these natural biopolymers are discussed in the context of self‐powered triboelectric applications. The common manufacturing methods for processing these materials into triboelectric devices are also discussed. In addition, the applications of the bio‐derived natural materials based TENGs for in vitro and in vivo applications are discussed. Finally, the outstanding challenges and potential opportunities for the development of bio‐derived natural materials based triboelectric devices targeting wearable and implantable human‐integrated applications are analyzed.

“…24 Among these patterns, cellulose lms with excellent mechanical properties and other functionalities have been widely used in exible devices, photonics, uidic devices, packaging materials, electrochemical energy storage, and solar gain regulators. [25][26][27] In recent years, several approaches of preparing porous cellulose lms have recently received extensive attention, including electrospinning (modied cellulose acetate lms), 28 a paper-making like process (mesoporous Cladophora cellulose lms), 29 forcespinning (forcespinning cellulose acetate lms, FS-CA) 30 and phase inversion. 31 Moreover, many studies have focused on the use of cellulose derivatives and bacterial cellulose as matrix, or mixing cellulose with other ingredients to prepare the porous lm, and further improvement in porosity is required.…”
