Summary: In this study, a crystal orientation regulation strategy by introducing dodecyl-benzene-sulfonic-acid as an additive in perovskite precursors is proposed to address the challenges faced by wide-bandgap (WBG) perovskite solar cells, including substantial open-circuit voltage (VOC) deficit and severe photo-induced halide segregation. The proposed method promotes the desired crystal orientation, passivates defects, and mitigates photo-induced halide phase segregation, leading to reduced nonradiative recombination, minimized VOC deficits, and enhanced operational stability of the devices. The resulting methylamine-free perovskite solar cells achieve impressive power conversion efficiencies (PCEs) of 22.40% and 20.13% for opaque and semitransparent devices, respectively. Furthermore, four-terminal tandem cells comprising WBG perovskite top cells and lower bandgap perovskite bottom cells showcase a remarkable PCE of 28.06%.

Summary: This study reports a facile strategy to reduce the open-circuit voltage losses in wide-bandgap perovskite solar cells using post-treatment with ammonium halides. By forming pure 2D perovskites atop 3D wide-bandgap perovskites through low-temperature annealing, optimal defect passivation and surface electric-field effects are achieved.

Summary: This study investigates the improvement of the quality of wide-bandgap (WBG) perovskite FA0.83Cs0.17Pb-(I0.8Br0.2)3 by incorporating lead chloride (PbCl2) into a lead acetate (PbAc2)-based precursor, resulting in enlarged grain sizes and improved crystallinity. The enhanced film quality leads to the suppression of nonradiative recombination and a reduction in defect density. Efficient WBG perovskite solar cells (1.66 eV) with an efficiency of 19.3% and a high Voc of 1.22 V were fabricated using a facile one-step spin-coating method without the need for an antisolvent. Notably, the unencapsulated devices retained 90% of their initial power conversion efficiency after storage in a dry box (10% humidity) for 800 h.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
