Summary: Solution processing of a bulk-heterojunction (BHJ) active layer in air with high relative humidity (RH) usually results in an inferior power conversion efficiency (PCE) of organic solar cells (OSCs). This study demonstrates that attaching a siloxane-terminated side chain on photoactive materials is a valuable chemical countermeasure to allow air-processing and withstand large variations in humidity. The PQSi705:Y6 active layer exhibited high humidity endurance and achieved a PCE of over 16.1%, showing the highest efficiency reported for BHJ active layers fabricated in high RH air.

Summary: In this study, a series of AzaBenzannulated PDI (AzaBPDI) multimers were synthesized and their potential as non-fullerene acceptors in bulk-heterojunction organic solar cells was investigated. The AzaBPDI dimers and trimer were easily prepared through a one-pot sequence of reactions. The AzaBPDI showed strong visible-light absorption and suitable LUMO energy levels, making them promising electron acceptors for organic solar cells. The combination of AzaBPDI with the donor polymer PM6 resulted in high device open-circuit voltages, demonstrating the potential of AzaBPDI for high-performance fullerene-free photovoltaics.

Summary: Organic solar cells (OSCs) have made rapid progress in recent years through the development of novel organic photoactive materials, particularly non-fullerene acceptors (NFAs). However, the understanding of the interplay between molecular structure and optoelectronic properties lags significantly behind. The potential role of energetic disorder in OSCs has received little attention, but recent studies have shown that state-of-the-art NFA-based devices can achieve both low energetic disorder and high power conversion efficiency (PCE).

Summary: By developing new naphthalene dimide-based polymer acceptors, we have achieved superior power conversion efficiency and mechanical robustness of all-polymer solar cells compared to devices based on N2200. The enhanced charge generation and transport abilities of the new polymer acceptors contribute to the improved performance, with high electron mobility and optimal domain size and purity. Furthermore, the blend of PBDB-T:PNDIHD/DT-0.41 exhibits excellent mechanical robustness, with a high initial power conversion efficiency maintained even after bending 1500 times.

Summary: This study investigates the nonequilibrium energy level displacement from the perspective of built-in potential caused by charge accumulation to explain the origin of charge separation driving force at negligible energy level offsets. Due to different carrier mobilities, carriers with high mobility are rapidly transmitted to the electrode, while carriers with low mobility remain in the material, resulting in charge accumulation. It is found that higher carrier mobility improves the efficiency of photovoltaic devices, but a balance of charge transport is needed.

Summary: This study investigates the structure-outdoor-stability relationship of Y-NFAs and reveals that Y-NFAs with long internal side-chains and fluorinated end-groups can improve device stability. Moreover, the performance loss of Y-NFA-based OSCs under illumination is driven by increased trap-assisted recombination over time.

Summary: By designing a new series of polymerized small molecule acceptor-based polymer acceptors, the authors controlled the donating moiety and backbone regioregularity to enhance electron mobility and power conversion efficiencies. The effects of different donating units and regioisomers on PCEs were found to be opposite, with the highest efficiency achieved by a specific blend with the highest electron mobility. The study highlights the importance of simultaneous engineering of the backbone building unit and regioregularity for high-mobility P-A and highly efficient all-PSCs.

Summary: Given the ease of synthesis and polarization of bromine compared to homomorphic fluorine and chlorine, it is surprising that high-performance brominated small molecule acceptors are rare. This may be due to undesirable film morphologies caused by steric hindrance and excessive crystallinity. To overcome this, three acceptors were constructed with stepwise bromination on central units to enhance intermolecular packing, crystallinity, and dielectric constant without damaging favorable intermolecular packing through end groups. As a result, PM6:CH22-based binary organic solar cells achieved the highest efficiency of 19.06% for brominated acceptors, and a record-breaking efficiency of 15.70% when the active layers were further thickened to around 500 nm. By exhibiting such a rare high-performance brominated acceptor, this work highlights the potential for achieving record-breaking organic solar cells through delicate bromination.
