Summary: A vacuum-assisted approach is developed to fabricate mirror-like, pinhole-free, highly crystalline, and uniform blade-coated perovskite films without using antisolvent and air knife. The effect of phenethylammonium iodide passivation at the top and bottom interfaces of a perovskite layer based on an FTO/NiOx/perovskite/C-60/BCP/Cu inverted p-i-n structure is systematically investigated. The encapsulated device, fabricated by blade coating under ambient conditions, retains 97% of its maximum efficiency after a 1000-hour photostability test.

Summary: Organic-inorganic hybrid perovskite solar cells (PSCs) show great potential in industrial commercialization, but efficiency and stability decrease when scaling up the device area. Blade-coating methods have been developed to fabricate large-area PSCs with uniform perovskite films. Ink engineering plays an important role in blade-coating, especially for crystallinity and defect control. This review summarizes the blade-coating method for large-area perovskite films, perovskite ink engineering, and recent advances in functional layer ink engineering and hole transporting material-free carbon-based PSCs.

Summary: Finite 2D/3D hierarchical perovskite structures are constructed using interfacial ligand confinement, resulting in efficient and stable inverted perovskite solar cells (PSCs) and modules. The introduction of a diamine masking reagent regulates cation exchange and forms a finite and dense 2D layer, improving top-contact passivation and electron extraction. The inverted PSCs and modules with finite 2D/3D perovskite layers achieve remarkable power conversion efficiencies of 24.7% and 21.6% (certified PCE of 21.2%), respectively, making them one of the best-performing inverted mini-modules reported so far. Encapsulated PSCs retain over 90% of their original PCE after 1000 hours of illumination. Overall, this work presents an effective approach for further advancing perovskite photovoltaics.

Summary: The poor interfacial contact and imperfections between the charge transport layer and perovskite film can lead to carrier recombination, inefficient charge collection, and inferior stability of perovskite solar cells (PSCs). To address this issue, a cinnamate-functionalized cellulose nanocrystals (Cin-CNCs) interfacial layer was introduced between SnO2 and the perovskite active layer. This improved the carrier transport ability, crystal growth, and long-term stability of PSCs. The results showed enhanced interfacial contact, cascade energy alignment, desirable perovskite film morphology, reduced interfacial defects, and suppressed charge recombination.

Summary: Atomic layer deposition (ALD) is an attractive technology for preparing sputtering buffer layers in semi-transparent perovskite solar cells (PSCs) and tandem solar cells. The ALD process can result in pin-hole layers due to island growth when the substrate is unreactive with the ALD reactants, which adversely affects anti-sputtering. In this study, ALD SnOx was used as the sputtering buffer layer in p-i-n structured PSCs, and impermeable ALD layers were formed by activating the unreactive substrate PCBM. The authors successfully fabricated ST-PSCs and perovskite/silicon tandem solar cells with high power conversion efficiencies (PCEs), as well as demonstrated the long-term stability of the devices.

Summary: This study introduces a simple and effective co-solvent engineering strategy to obtain pinhole-free and defect-less perovskite film without the use of anti-solvents. The addition of a co-solvent with strong coordination capacity and weak interaction with the main solvent allows for the fabrication of uniform and compact perovskite polycrystalline films. With the optimal co-solvent N-methylpyrrolidone (NMP) and without the use of anti-solvent, a champion power conversion efficiency (PCE) of 22% has been achieved. This strategy provides guidance for co-solvent selection in anti-solvent free perovskite solar cells (PSCs) and promotes their commercial application.

Summary: In this study, indium (In) ions were introduced into flexible Cu2ZnSn(S,Se)(4) (CZTSSe) solar cells to modify the back interface and passivate deep level defects in CZTSSe bulk. The results showed that In doping effectively inhibited the formation of secondary phase and V-Sn defects, decreased the barrier height at the back interface, passivated deep level defects in CZTSSe bulk, increased carrier concentration, and significantly reduced the V-OC deficit. Eventually, a flexible CZTSSe solar cell with a power conversion efficiency of 10.01% was achieved. This synergistic strategy of interface modification and bulk defects passivation through In incorporation provides a new approach for fabricating efficient flexible kesterite-based solar cells.

Summary: Direct growth of redox-active noble metals and rational design of multifunctional electrochemical active materials play crucial roles in developing novel electrode materials for energy storage devices. In this regard, silver (Ag) has attracted great attention in the design of efficient electrodes. The construction of multifaceted heterostructure cobalt-iron hydroxide (CFOH) nanowires (NWs)@nickel cobalt manganese hydroxides and/or hydrate (NCMOH) nanosheets (NSs) on the Ag-deposited nickel foam and carbon cloth (i.e., Ag/ NF and Ag/CC) substrates is reported. The as-fabricated Ag@CFOH@NCMOH/NF electrode delivered superior areal capacity value of 2081.9 μA h cm-2 at 5 mA cm-2. Moreover, as-assembled hybrid cell based on NF (HC/NF) device exhibited remarkable areal capacity value of 1.82 mA h cm-2 at 5 mA cm-2 with excellent rate capability of 74.77% even at 70 mA cm-2. Furthermore, HC/NF device achieved maximum energy and power densities of 1.39 mW h cm-2 and 42.35 mW cm-2, respectively. To verify practical applicability, both devices were also tested to serve as a self-charging station for various portable electronic devices.
