“…Figure 6 shows the corresponding current density-voltage (J-V) curves. The photovoltaic performance of the resulting PTB7:PC 71 BM-based solar cells, consistent with analogous systems reported in the literature [16,22,23], are comparable, giving PCE values between 6.5 and 6.9%. This confirms the general quality and suitability of all the NP inks/films for photovoltaic applications, regardless of the adopted reaction solvent.…”

“…Moreover, to evaluate the electrical performance of the resulting thin-films, we fabricated a set of inverted OSCs using ZnO NPs as an ETL and PTB7:PC 71 BM as a photoactive blend. The resulting devices exhibited power conversion efficiencies (PCEs) between 6.5 and 6.9%, consistent with analogous systems reported in the literature [22,23], thus validating the effectiveness of the proposed synthetic procedures.…”

Among solution-processable metal oxides, zinc oxide (ZnO) nanoparticle inks are widely used in inverted organic solar cells for the preparation, at relatively low temperatures (<120 °C), of highly efficient electron-transporting layers. There is, however, a recent interest to develop more sustainable and less impacting methods/strategies for the preparation of ZnO NPs with controlled properties and improved performance. To this end, we report here the synthesis and characterization of ZnO NPs obtained using alternative reaction solvents derived from renewable or recycled sources. In detail, we use (i) recycled methanol (r-MeOH) to close the loop and minimize wastes or (ii) bioethanol (b-EtOH) to prove the effectiveness of a bio-based solvent. The effect of r-MeOH and b-EtOH on the optical, morphological, and electronic properties of the resulting ZnO NPs, both in solution and thin-films, is investigated, discussed, and compared to an analogous reference material. Moreover, to validate the properties of the resulting materials, we have prepared PTB7:PC71BM-based solar cells containing the different ZnO NPs as a cathode interlayer. Power conversion efficiencies comparable to the reference system (≈7%) were obtained, validating the proposed alternative and more sustainable approach.

“…Researchers can modify the active layer's nanoscale shape and enhance the close contact between various materials by carefully selecting and designing interfacial layers. This morphological regulation enhances the efficacy of exciton dissociation, charge transfer, and light absorption [55]. The contribution of interfacial materials to device stability and environmental protection is another crucial factor.…”

For over a decade, donor-acceptor blends composed of organic donors and fullerene acceptors dominated indoor organic solar cells (IOSCs). Numerous researchers have invested time to conduct extensive studies on developing new donor acceptor materials, interlayers, minimizing energy losses, and enhancing the open-circuit voltage (V OC) through device and material engineering, and optimizing device architectures to achieve highly efficient, environmentally stable, and commercially acceptable IOSCs. Through such efforts, the maximum power conversion efficiencies (PCEs) of IOSCs have surpassed 35%. In this regard, the transition from a fullerene to non-fullerene acceptor (NFA) is a useful strategy for enhancing the PCEs of IOSCs by allowing adjustment of the energy levels for compatibility with the indoor light spectrum and by improving photon absorption in the visible range, thereby boosting photocurrent generation and enhancing V OC. NFA-based indoor organic photovoltaic systems have recently drawn interest from the scholarly community. To compete with the standard batteries used in the Internet of Things devices, additional research is needed to enhance several characteristics, including manufacturing costs and device longevity, which must maintain at least 80% of their initial PCEs for more than 10 years. Further development in this field can greatly benefit from a thorough and comprehensive review on this field. Hence, this review explores recent advances in IOSCs systems based on NFAs. First, we explain several methods used to create extremely effective IOSCs, IOSCs based on fullerene acceptors are next reviewed and discussed. The disadvantages of using fullerene acceptors in IOSCs are noted. Then, we introduce NFAs and explore existing research on the subject. Finally, we discuss the commercial potential of NFA-based IOSCs and their future outlook.

Black phosphorus (BP) is considered among the promising material for electronic devices. A wide range of studies involving properties, exfoliation, and applications of thin‐layered BP nanosheets (NSs) has been put forward. Along with understanding properties of thin‐layered BP NSs, efforts to enlighten the intrinsic characteristics of the BP film should be also accompanied to extend applications of the material. In this study, a facile and efficient inkjet printing approach is introduced to fabricate patterned BP films. This approach successfully addresses the complexity of the ink formulation and thus enables to pattern the high‐quality BP film at as high a resolution as tens of micrometers. The printed BP pattern provides its intrinsic characteristics including electronic properties, conducting mechanism, and stability, which are essential to advancing the printed BP electronic device. By integrating the printed BP pattern into a diode device, its potential for electronic devices is demonstrated. This inkjet printing technique will facilitate the development of printing patterns of 2D materials in a facile and cost‐effective manner and further boost the research on advanced electronic devices.
