Summary: The power conversion efficiency (PCE) of polymer solar cells (PSCs) with a bulk heterojunction (BHJ) structure can be enhanced by incorporating Fe3O4 magnetic nanoparticles (MNPs) and an external magnetic field (EMF). The coercive electric field within the Fe3O4 MNPs generated by the EMF facilitates charge generation and accelerates charge carrier transport, leading to an improvement in PCE.

Summary: In a flexible perovskite solar cell, the interface between perovskite and the electron-transporting layer at the bottom is crucial for efficiency and reliability. By incorporating a liquid crystal elastomer interlayer, the charge transfer channel in the device is toughened, leading to optimized charge collection and reduced charge recombination. The flexible device achieves an efficiency of 22.10%, and demonstrates long-term stability with over 80% efficiency after 1570 hours and 86% efficiency after 5000 bending cycles. Furthermore, the flexible solar cell chips are integrated into a wearable haptic device for a pain sensation system in virtual reality.

Summary: Ternary bulk heterojunction organic solar cells have energy offsets between multiple donors and acceptors. This study observed that charge carriers have higher possibilities to transport in polymeric materials, even in low dosage. A polymer bridge assisted charge transport mode in small molecules is proposed after the energy offset exceeds the threshold.

Summary: The alkyl linker-based self-assembled monolayer (SAM) has limitations in its hole-transporting capability and stability. In this study, a series of conjugated SAMs with enhanced photo and electrical stability were reported. The conjugated molecular structure not only improves charge transport but also stabilizes the electron-rich arylamines. An optimal conjugated SAM, in combination with a standard triple cation perovskite, achieved efficient inverted PSCs with high stability. The findings suggest that conjugated SAMs are promising for further advancement of inverted PSCs.

Summary: Three non-fused ring acceptors (NFREAs), C8-2F, FC8-2F and MeC8-2F, were synthesized by introducing different functional atoms/groups into the para-position of phenyl in the OPT units. The absorption spectrum of the NFREAs can reach about 950 nm with band-gaps of 1.28-1.32 eV due to the strong electron donating ability of OPT. By changing the substituents on the OPT units, their Flory-Huggins interaction parameter (chi) with the donor can be greatly influenced and different phase separation behavior can be achieved. Blending FC8-2F with PBDB-TF achieves a solar cell with short circuit current density (J(sc)) of 23.21 mA.cm(-2), fill factor (FF) of 72.11%, and the highest power conversion efficiency (PCE) of 12.42%.

Summary: The researchers have successfully achieved high efficiency and mechanical reliability in all-polymer organic photovoltaic (OPV) cells by introducing a polymer donor, PBDB-TF, with a high molecular weight. By adding the high molecular weight PBDB-TF as a third component into the PBQx-TF:PY-IT blend, they optimized the heterojunction morphology, enhancing charge transport efficiency and mechanical stress dissipation. As a result, the all-polymer OPV cells based on the ternary blend film showed a maximum power conversion efficiency (PCE) of 18.2% with a fill factor of 0.796. The flexible OPV cell also achieved a decent PCE of 16.5% with high mechanical stability. These findings provide a promising strategy for improving the mechanical properties and boosting the photovoltaic performance of all-polymer OPV cells.

Summary: Great progress has been made in the power conversion efficiencies (PCEs) of organic photovoltaics (OPVs) by using non-fullerene acceptors (NFAs). In order to further improve device performance, it is important to understand the design strategies, packing information, and intermolecular interactions of NFAs at the atomic level. This review highlights recent advances in the study of single crystal structures of NFAs in OPVs, as well as the relationship between molecular design strategies, packing arrangement, and their corresponding properties. The challenges and future development of new electron acceptors with ideal single crystal structures and packing modes for next-generation organic photovoltaics are also discussed.

Summary: A room-temperature-processed SnO2:OH electron-transport layer with reduced defect density and better energy band alignment has been demonstrated for flexible perovskite solar cells. The formation of hydrogen bonds at the interface produces an efficient electron-transfer channel, leading to enhanced electron extraction from the perovskite. With this ETL, a large-area flexible perovskite solar module reaches a PCE value of 18.71%, the highest reported so far for flexible perovskite solar modules. The long-term stability is also greatly improved due to the high quality perovskite film and the strong coupling between SnO2:OH and perovskite layer caused by hydrogen bonds, which effectively inhibits moisture permeation.

Summary: In the past decade, extensive research has been conducted on halide perovskites, exploring their applications beyond photovoltaics in areas such as photothermal and thermoelectric energy conversion, light-emission, high-energy electromagnetic radiation detection, memristors/artificial synapses, and ferroelectricity. The traditional wet chemistry synthesis of halide perovskites using solution medium has limitations in terms of solvent cost, environmental impact, treatment complexity, and post-processing convenience. This work discusses new opportunities in solvent-free synthesis, including vapor deposition and mechanochemical methods, to pave the way for future development in perovskite-based applications.
