Lead halide perovskite solar cells (PSCs) have achieved remarkable efficiencies comparable to those of their established silicon counterparts at a very fast pace. Moreover, solution-processable facile technologies offer low-cost, low-temperature, scalable fabrication these cells. Numerous studies focused on improving the performance, stability, and processing PSCs. However, potential lead toxicity poor long-term stability impede commercialization. In recent years, several developed novel encapsulants for PSCs that can simultaneously improve leakage. Although improvements been made both fronts, no solution date could achieve level leakage prevention result in market breakthrough. Here, we analyze PSC encapsulation techniques undertaken years. While most related either or toxicity, note be solved together with suitable encapsulant is impermeable moisture Pb2+ ions. addition, lack unified standard testing protocol has led under variety temperatures, humidities, environmental conditions. Therefore, urgency cannot overlooked.

Abstract The preferential growth of α‐phase formamidinium perovskite (α‐FAPbI 3 ) at low temperatures can be achieved with the incorporation chloride‐based additives, methylammonium chloride (MACl) being most common example. However, compared to other less‐volatile MACl only remains in growing film for a short time before evaporating during annealing, primarily influencing early stages formation. In addition, evaporation as methylamine (MA 0 and HCl introduce side reaction between MA (FA), undermining compositional purity phase stability α‐FAPbI . this study, it is demonstrated that addition iodine (I 2 into FAPbI precursor solution containing suppresses MA‐FA annealing. Additionally, delayed owing strong interaction triiodide. added I facilitates spontaneous prior an improved bottom morphology due formation fewer byproducts. Perovskite solar cells derived from ‐incorporated deliver champion power conversion efficiency 25.2% attributed suppressed non‐radiative recombination.

Abstract This work introduces a simplified deposition procedure for multidimensional (2D/3D) perovskite thin films, integrating phenethylammonium chloride (PEACl)‐treatment into the antisolvent step when forming 3D perovskite. simultaneous and passivation strategy reduces number of synthesis steps while simultaneously stabilizing halide film improving photovoltaic performance resulting solar cell devices to 20.8%. Using combination multimodal in situ additional ex characterizations, it is demonstrated that introduction PEACl during formation slows down crystal growth process, which leads larger average grain size narrower distribution, thus reducing carrier recombination at boundaries device's stability. The data suggests annealing wet film, diffuses surface hydrophobic (quasi‐)2D structures protect bulk from humidity‐induced degradation.

Perovskite solar cells (PSCs) have gained tremendous research interest recently owing to several advantages, including low material cost, facile solution processability, bandgap tunability, and alluring device efficiency. The organic formamidinium (FA) cation‐based perovskites are mainly considered as one of the potential candidates for charge carrier generation due their excellent properties, such thermal stability than traditional perovskites. However, inevitable unfavorable polymorphism (i.e., α δ ) at room temperature still forms basis numerous works allow fabrication a high‐quality absorber enhances PSCs performance. studies resolve contemporary techniques (e.g., passivation strategy) with recent novel methods presented in this review form essence improvements PSCs. morphology also influences charge‐transfer behavior device's lifetime. Therefore, understanding these properties is essential improve quality avoid many defects. This focuses on structure pure mixed FA various halides, cation's role composition. And comprehensive overview double, triple, quadrupole results proper scientific explanations understand physics.

Abstract 70% of the earth's surface is covered by ocean, and it represents a promising renewable clean energy reservoir that waits for further exploration. Although hydrogen (H 2 ) boasts high density 143 MJ kg −1 environmentally friendly attributes, widespread commercialization green H production remains formidable challenge. With huge amounts water, ocean presents an opportunity generating fuel through process seawater electrolysis. This review introduces ocean‐driven, self‐powered blue conversion devices, including triboelectric nanogenerators (TENGs), magnetoelastic generators (MEGs), solar cells. They are able to convert from water waves, wind, energy, into electricity on‐site seawater‐splitting generation. systematically reports this compelling approach introducing fundamental principles devices showcasing practical applications. Additionally, aiming promote future research in field sustainable also delves development novel harvesting systems with efficiency large‐scale effective production.

Abstract Active oxygen highly affects the efficiency and stability of perovskite solar cells (PSCs) owing to capacity either passivate defects or decompose lattice. To better understand in‐depth interaction, we demonstrate for first time that photooxidation mechanism in all‐inorganic film dominates phase deterioration kinetics by forming superoxide species presence light oxygen, which is significantly different from organic‒inorganic hybrid even tin‐based perovskites. In perovskites, prefer oxidize longer weaker Pb‒I bond PbO I 2 , leaving much stable CsPbBr 3 phase. From this chemical proof‐of‐concept, employ an organic bioactive factor, Tanshinone IIA, as a sweeper enhance environmental tolerance inorganic perovskite, serving “skincare” agent anti‐aging organisms. Combined with another key point on healing defective lattice, best carbon‐based CsPbI Br cell delivers high 15.12% superior against light, humidity, heat attacks. This method also applicable p‒i‒n inverted (Cs 0.05 MA FA 0.9 )Pb(I 0.93 0.07 ) 23.46%. These findings not only help us decomposition mechanisms depth but provide potential strategy advanced PSC platforms.

Inorganic CsPbI2Br perovskite solar cells have attracted widespread attention due to their outstanding performance and photo-thermal stability. However, the rapid crystallization of solution-processed film often results in poor crystallinity a high density defects, which seriously restrict improvement device performance. Here, we introduce dual-functional additive, 4-amino-5-aminomethyl-2-methylpyrimidine (AMP), regulate reduce defect film. The introduction AMP notably improves morphology promotes preferred crystal orientation. C=N amino groups interact with Pb2+ Br- perovskite, respectively, effectively passivating defects improving carrier lifetime. As result, power conversion efficiency optimized carbon-based hole-transport layer-free reaches 13.30%, exceeds 10.66% control device. environmental light stability is also significantly improved. This work provides valuable insights into development high-performance all-inorganic via additive strategies.
