Summary: Layered d-MnO2 nanocrystals were prepared through a facile precipitation reaction at ambient conditions using Na2SO3 as a reductant. The enhanced electrochemical performance of d-MnO2 can be attributed to the high content of co-preinserted K+ and Na+ ions and water. Specifically, d-MnO2 exhibits a high specific capacitance of 303.7 F g(-1) at 0.5 A g(-1) and shows excellent cycle stability. Additionally, an asymmetric supercapacitor (ASC) was fabricated using d-MnO2 as the positive electrode and reduced graphene oxide (RGO) as the negative electrode, achieving a large energy density of 53.2 Wh kg(-1) at 250 W kg(-1) with 91.1% capacitance retention after 5000 cycles.

Summary: CsPbI2Br is a promising material for perovskite solar cells due to its reasonable bandgap and good thermal stability. However, the efficiency of CsPbI2Br solar cells is currently lower than that of organic-inorganic hybrid solar cells, primarily due to the poor crystal quality of CsPbI2Br. In this study, the addition of Ti3C2Tx MXene nanosheets to the CsPbI2Br photoactive layer is reported. The improved crystallinity and reduced defect density, along with the formation of a Schottky junction between the MXene nanosheets and CsPbI2Br, enhance the separation and transfer of the photogenerated electron-hole pairs, leading to a significantly increased power conversion efficiency. Additionally, the MXene-added CsPbI2Br layers exhibit improved humidity resistance.

Summary: NaCl and nitrogen-doped graphene quantum dots (N-GQDs) are introduced as binary additives in perovskite precursor, resulting in high-quality photoactive films. The addition of Cl- aligns the energy level of CsPbI2Br with that of bromine, promoting carrier transport and reducing energy loss. N-GQDs at grain boundaries enhance conductivity and suppress carrier recombination. The trap state density of the CsPbI2Br film is reduced, leading to improved carrier lifetime and surface morphology. The proposed binary additives optimization strategy achieves a PCE of 15.37% for CsPbI2Br PSCs, representing a relative increment of 22.76% compared to pristine PSCs.

Summary: This study introduces a simple additive-engineering scheme, adding silicon dioxide (SiO2) nanoparticles into the CsPbI2Br photoactive layer, to improve the overall performance of inorganic perovskite solar cells. The addition of SiO2 nanoparticles not only improves the crystallization quality, reduces trap density, and enhances resistance to moisture and silver diffusion, but also enhances light absorption and increases the short-circuit current density. The power conversion efficiency (PCE) is increased by approximately 18.39% with the addition of SiO2 nanoparticles, achieving a PCE of 15.32% compared to the control device without SiO2 nanoparticles. Furthermore, the SiO2 nanoparticle-added CsPbI2Br device exhibits improved stability, with over 80% retention of initial PCE after aging in air with a relative humidity of 20-30% for 160 hours.
