“…Previously reported literature suggests that the g-butyrolactone (GBL) solvent is suitable for iodine halogen atom perovskites, in which acetonitrile (ACN) will act as an antisolvent, and DMF, as well as dimethlysulfoxide (DMSO), are suitable solvents for the bromine atom perovskite, in which formic acid (FAH) acts as an antisolvent. [19][20][21] The FA-based perovskite is highly suitable for growing a single-crystal using the ITC method, and retrograde solubility enables the facile and rapid growth of the PSCs. Here, an iodine-based singlecrystal is grown by selecting GBL as a solvent.…”

“…In ITC supersaturation is obtained by increasing the temperature, and is therefore applied to precursors whose solubility in a given solvent decreases with increasing temperature (exothermic dissolution). Typically the precursors (MAX and PbX 2 ) are dissolved in GBA or GBL to form MAPI (6,(64)(65)(66)(67)(68), DMF to form MAPB (66,67,69,70) or DMSO to form MAPC (66,71).…”

“…In order to grow MAPI SC at low temperature, an anti-solvent (ACN) can be added to the commonly used ITC solvent (GBL), thus reducing the solubility of the perovskite precursors. By tuning the anti-solvent concentration bulk SCs can be grown in a wide temperature range (30 ¶ C-80 ¶ C), with best-quality crystals achieved at 60 ¶ C (68).…”

“…By tuning the anti-solvent concentration bulk SCs can be grown in a wide temperature range (30-80 °C), with best-quality crystals achieved at 60 °C. [69] In alternative, the formation of 3 I − traps can be prevented by halting the oxidation of I − into 3 I − , by adding a strong reducing agent such as hypophosphorous acid (H 3 PO 2 ) to the ITC precursor solution (Figure 4d). A 2 orders of magnitude boost in photocurrent was obtained with 3 I − -free MAPI SCs.…”

Lead halide perovskite solar cells have been gaining more and more interest. In only a decade, huge research efforts from interdisciplinary communities enabled enormous scientific advances that rapidly led to energy conversion efficiency near that of record silicon solar cells, at an unprecedented pace. However, while for most materials the best solar cells were achieved with single crystals (SC), for perovskite the best cells have been so far achieved with polycrystalline (PC) thin films, despite the optoelectronic properties of perovskite SC are undoubtedly superior. Here, by taking as example monocrystalline methylammonium lead halide, the authors elaborate the literature from material synthesis and characterization to device fabrication and testing, to provide with plausible explanations for the relatively low efficiency, despite the superior optoelectronics performance. In particular, the authors focus on how solar cell performance is affected by anisotropy, crystal orientation, surface termination, interfaces, and device architecture. It is argued that, to unleash the full potential of monocrystalline perovskite, a holistic approach is needed in the design of next‐generation device architecture. This would unquestionably lead to power conversion efficiency higher than those of PC perovskites and silicon solar cells, with tremendous impact on the swift deployment of renewable energy on a large scale.

This work carefully studied the transition from 3D perovskite to 2D perovskite. Our system includes single crystals (SCs) of MAPbBr3, which were dipped in a solution of barrier molecules. Three monoammonium cations and one di‐ammonium cation were studied. Absorbance and cathodoluminescence were used to follow the formation of low‐dimensional perovskite on the SC surface. Quantitative nuclear magnetic resonance and scanning electron microscopy assist in quantitatively tracking the exchange process. We followed the barrier molecules' concentration during the exchange process and their penetration depth into the 3D single crystal. The short aliphatic chain penetrates much farther into the crystal (ca. 450 mm) than the long aliphatic chain barrier molecule. In contrast, the process time is the opposite: the long aliphatic chain requires 5 days to achieve an equilibrium state compared with 15 days for the short aliphatic chain. Ab initio calculations indicate that the exchange process initiates due to the methylammonium vacancies on the surface, and the process is inhibited by the interactions between the ‐NH3 group and the PbBr2 planes. This work sheds light on the kinetics and thermodynamics of the transition from 3D to 2D perovskites, which is important for stabilizing the hybrid perovskites.
