Summary: In this study, one-dimensional TiO2 nanorod arrays were used as scaffolds in PeSCs, guiding the deposition of PbI2 and stabilizing the alpha-FAPbI(3) crystalline structure. Additionally, phenyl-ethylammonium iodide was used to passivate the surface defects of the perovskites to enhance device performance. The optimized alpha-FAPbI(3) PeSCs achieved a power conversion efficiency of up to 21.89% with weak hysteresis, and retained 94% of the initial efficiency after 800 hours of storage in a dark room at room temperature. The alpha-FAPbI(3) SCs based on TiO2 nanorod scaffolds can serve as a reference for the development of low-temperature perovskite optoelectronic devices.

Summary: To solve the toxicity issues related to lead-based halide perovskite solar cells, a lead-free double halide perovskite Cs2AgBiBr6 is proposed. However, the reduced rate of charge transfer affects the optoelectronic performance of double perovskites. By using interface engineering, a series of pyridine-based small molecules with different arms attached to the pyridine core are designed as hole-selective materials. The solar cells fabricated using Cs2AgBiBr6 as a light harvester and the designed hole-selective layer showed an unprecedented 2.9% power conversion efficiency. Our findings provide guidance for designing small molecules for electro-optical applications and developing lead-free perovskite materials for solar applications.

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.

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.
