“…We fabricated the FA 0.95 Cs 0.05 PbI 3 perovskite films by the two‐step method with high device reproducibility to investigate the impact of thermocompression on perovskite. [ 22 ] The temperature and pressure applied to the perovskite film during thermocompression are consistent with those used in the actual lamination process (120 °C, 70 kPa).…”

Vacuum lamination encapsulation is widely adopted to prolong the duration of perovskite solar cells (PSCs) in real operation. However, additional encapsulant along with rigorous processing conditions leads to severe power conversion efficiency (PCE) loss to the corresponding devices. Herein, thermal and optical simulations and experiments are combined, to analyze the mechanisms for device failure during vacuum lamination. Single‐glass encapsulation structure is proposed, which exhibits enhanced thermal conductivity, ensuring thorough and homogeneous melting of the encapsulant during the lamination process. This effectively mitigates delamination within the module and reduces parasitic photocurrent losses in the PSC device after encapsulation. Notably, the single‐glass encapsulation devices retain 88% of their initial PCE after 1000 h damp heat test and successfully pass the thermal cycling standard (IEC 61 215:2016) with 95% retention of initial PCE after 250 cycles.

“…S5,† the I/Pb ratios of the pristine, in situ , post, and dual films are 3.91, 3.63, 3.70, and 3.51, respectively, indicating that the accumulation of iodine ions in perovskite films decreased after passivation treatment, which can be attributed to the suppressed migration of iodine ions in the treated perovskite film. 21 Ion migration of iodine is generally believed to be dominated by grain boundaries in polycrystalline films, making it more difficult for ions to migrate in films with large particle sizes. 22 Therefore, the smaller I/Pb ratios in the in situ and dual films should be due to the increase in grain size, which can be further confirmed by scanning electron microscope (SEM) images.…”

“…The highest-efficiency p-i-n halide perovskite solar cell reported as of February 2023 had a 25.35% efficiency (certified 24.05%), with the cell architecture and J – V curve shown in Figure d; the highest certified efficiency stands at 24.3% . There have been only ∼10 reported p-i-n devices with PCE > 24%, and only two above 25%. − These cells also shared a majority-FAPbI 3 absorber layer, but there was more variance in charge transport layer choice between them. NiO x and MeO-2PACZ are both popular bottom HTLs for high-efficiency p-i-n cells, and the top ETL is usually C 60 or PCBM.…”

Three-dimensional (3D) organic–inorganic lead halide perovskites have emerged in the past few years as a promising material for low-cost, high-efficiency optoelectronic devices. Spurred by this recent interest, several subclasses of halide perovskites such as two-dimensional (2D) halide perovskites have begun to play a significant role in advancing the fundamental understanding of the structural, chemical, and physical properties of halide perovskites, which are technologically relevant. While the chemistry of these 2D materials is similar to that of the 3D halide perovskites, their layered structure with a hybrid organic–inorganic interface induces new emergent properties that can significantly or sometimes subtly be important. Synergistic properties can be realized in systems that combine different materials exhibiting different dimensionalities by exploiting their intrinsic compatibility. In many cases, the weaknesses of each material can be alleviated in heteroarchitectures. For example, 3D-2D halide perovskites can demonstrate novel behavior that neither material would be capable of separately. This review describes how the structural differences between 3D halide perovskites and 2D halide perovskites give rise to their disparate materials properties, discusses strategies for realizing mixed-dimensional systems of various architectures through solution-processing techniques, and presents a comprehensive outlook for the use of 3D-2D systems in solar cells. Finally, we investigate applications of 3D-2D systems beyond photovoltaics and offer our perspective on mixed-dimensional perovskite systems as semiconductor materials with unrivaled tunability, efficiency, and technologically relevant durability.
