Abstract Hydrogen, produced through a zero‐pollution, sustainable, low‐cost, and high‐efficiency process, is regarded as the “ultimate energy” of 21st century. Solar water‐splitting techniques have immense potential to make idea reality. Two promising approaches, photovoltaic‐electrolysis (PV‐EC) photoelectrochemistry (PEC), demonstrated solar‐to‐hydrogen conversion efficiency over 10%, which minimum required for competitively priced, large‐scale systems. Extensive studies PV‐EC PEC devices reported within past five decades show increasing design complexity. To accurately describe gap between laboratory research practical application, basic principles concepts are elaborated clarified. The history these developments systematically summarized, comprehensive techno‐economic analysis solar hydrogen production 10 000 kg H 2 day −1 performed. shows that no system currently competitive with methods based on fossil fuels, but development electrolyzers cost‐competitive components (especially cation/anion exchange membranes) can accelerate progress.

Perovskite photovoltaics have shown great promise in device efficiency but also the of scalability through solution-processed manufacture. Efforts to scale perovskites been taken printable mesoporous scaffolds and slot die coating flexible substrates roll-to-roll (R2R). However, date there has no demonstration entirely R2R-coated devices due lack a compatible solution-processable back electrode; instead, high-value evaporated metal contacts are employed as post process. Here, this study, combination low-temperature structure R2R-compatible solution formulations is make fully R2R architecture overcoming interlayer incompatibilities recombination losses. Therefore, n-i-p SnO2 /perovskite/poly(3,4-ethylenedioxythiophene)/carbon form an ohmic contact between p-type semiconductor carbon electrode. In particular, results show that small-scale efficiencies 13-14% achieved, matching performance gold electrodes. Also, perovskite prototype represents game changer, reaching over 10% (10.8) stabilized power conversion with unencapsulated long-term stability retaining 84% its original 1000 h under 70% RH 25 °C.

Abstract Despite remarkable progress in perovskite solar cells (PSCs), the unsatisfying stability strongly interrelated with defect density remains main obstacle for commercialization. Herein, a synergetic passivation method is judiciously designed that consists of precursor engineering strategy based on an ionic liquid 1‐butylsulfonate‐3‐methylimidazolium dihydrogen phosphate (BMDP), and two‐stage annealing (TSA) treatment to sufficiently passivate defects enhance performance further. It found multifunctional groups from BMDP have strong chemical interactions form chelated complexes components thus effectively passivating intrinsic defects. Synergized by sequential TSA treatment, formed hydrophobic can be precisely controlled filling along grain boundaries (GBs) surfaces, leading wrapping grains significant GBs. Consequently, both deep‐ shallow‐level bulk, at GBs surface are passivated, resulting champion efficiency 24.20%. Impressively, resultant unencapsulated films corresponding devices exhibit admirable maintaining 83.9% initial composition 4000 h aging moist air, 81.7% original structure after continuous heating 1600 h, 97% power conversion 1000 under illumination.
