Compared with liquid electrolytes, the solid polymer electrolyte (SPE), which possesses improved thermal and mechanical stability, is believed broadest potential application for satisfying safety needs of advanced electrochemical devices. However, some breakable SPEs could lead to catastrophic failure batteries that triggered by a short circuit. In present contribution, new class SPE containing disulfide bonds urea groups reported. The hydrogen bonding between metathesis reaction endows high...
A pre-embedding mixed A-cation halide strategy is developed to eliminate the residual unstable PbI 2 and lattice strain near buried interface of perovskite layer for stability improvement formamidinium-based solar cells.
Abstract Organic ammonium salts have been widely used for defect passivation to suppress nonradiative charge recombination in perovskite solar cells (PSCs). However, they are prone form undesirable in‐plane favored 2D perovskites with poor transport capability that hamper device performance. Herein, the defects role of alkyldiammonium including 1.6‐hexamethylenediamine dihydriodide (HDAI 2 ), 1,3‐propanediamine (PDAI and 1.4‐butanediamine (BDAI ) formamidinium‐cesium is systematically...
Stability and scalability are essential urgent requirements for the commercialization of perovskite solar cells (PSCs), which retarded by non-ideal interface leading to non-radiative recombination degradation. Extensive efforts devoted reducing defects at surface. However, effects buried on degradation need be further investigated. Herein, an omnibearing strategy modify top surfaces film reduce interfacial defects, incorporating aluminum oxide (Al2 O3 ) as a dielectric layer growth scaffolds...
Although the fabrication of two-dimensional (2D)/three-dimensional (3D) halide perovskite heterostructures has been employed to balance long-term stability and high efficiency solar cells, formation metastable quasi-2D perovskites remains most serious challenge. Here, we demonstrate that large lattice mismatch derived from cation differences between 2D 3D are key avoiding unintended phases in preparation 2D/3D bulk heterostructure because phase transformation becomes less thermodynamically...

Despite having attractive stability over the volatile methylammonium (MA) cation, double-cation (Cs, FA) perovskite solar cells are largely overlooked because of their inferior performance compared to MA-based devices. Among all device engineering strategies, surface passivation represents a promising approach acquire improved performance. However, effective strategies have not yet been developed for attaining efficiencies MA-free close theoretical limit. Herein, fullerene passivators with...
Abstract The wide‐bandgap (WBG) perovskite solar cells (PSCs) and narrow‐bandgap organic (OSCs) integrated tandem (TSCs) show great potential for overwhelming single junction structure, especially the advantage of applying orthogonal solvents allowing solution processed each subcell. However, WBG with high Br content suffers from serious phase segregation voltage loss. commonly used interconnection layer (ICL) in TSCs requires a vacuum‐deposited thin metal recombination leading to remarkable...

Quasi-2D perovskites are known for their long-term environmental stability. In this system, bulky spacers expected to inhibit ion migration and reduce interfacial nonradiative recombination. However, it also presents challenges charge transportation at the same time. As a result, possibility great potential of such quasi-2D wide band gap (WBG) solar cells have rarely been explored. Here, we specialize in formamidinium-based WBG perovskites, obtaining preferential crystal orientation...
