“…One-pot colloidal synthesis of Cs 1-X FA X PbI 3 Pe-CQDs was difficult due to the optimized reaction temperature difference between Cs (180 °C) and FA (80 °C) precursors. 146 Jang's group developed the one-pot synthesis method of Cs 1-X FA X PbI 3 Pe-CQDs from initial crystallization by injecting mixed A-site cation precursor. This method can finely control the ratio of mixed cations of Pe-CQDs by adjusting the A-site precursor ratio.…”

Perovskite colloidal quantum dots (Pe-CQDs) are promising materials for the next-generation optoelectronic devices due to their outstanding material properties derived from perovskites and QDs. Among the various synthesis methods, the hot injection (HI) method has been mainly used to fabricate the active layer of photovoltaics. For the effective application of Pe-CQDs, the synthesis variables that determine the properties of Pe-CQDs should be determined. The variables of Pe-CQDs synthesis can be divided into two types. First, the crystal nucleation and growth rates can be physically modified by reaction time and temperature. Second, the synthesis mechanism can be chemically modified by adjusting the precursors and injection type. In this review, various HI-based strategies are systematically classified and investigated. Furthermore, we discuss on how Pe-CQDs with enhanced properties prepared by advanced synthesis strategies affect the power conversion efficiency and stability of photovoltaics. Finally, the current limitations of Pe-CQD synthesis and future agendas are presented.

“…An additional possibility is to change the A + site cation, which also influences the optical properties but mostly the thermal properties of the perovskite . To date, state-of-the-art PSCs have used perovskites with mixed cations and mixed halides. , There are two main SC structures based on perovskites: the inverted structure (p-i-n) and the n-i-p structure. In both structures, the hole-transport layer (HTL) and the electron-transport layer (ETL) are essential.…”

In perovskite solar cells, mixed-cation perovskites offer high power conversion efficiencies due to the diverse A + cations. In these cells, the perovskite is sandwiched between electron-transport and hole-transport layers (HTL). This study presents mono-and mixed-cation perovskites in HTL-free cells: monocation (MAPbI 3 , FAPbI 3 ) and mixed cation (MA 0.8 FA 0.2 PbI 3 , FA 0.8 MA 0.2 PbI 3 ). Surprisingly, monocation perovskites performed better than mixed-cation perovskites in HTL-free cells due to superior hole mobility and p-type behavior, while mixed-cation perovskites work better in n-i-p and p-i-n cells. These findings highlight the electronic differences for various types of perovskite, impacting the commercialization of perovskite solar cells.

Iodide perovskites have demonstrated their unprecedented high efficiency and commercialization potential, and their superior optoelectronic properties, such as high absorption coefficient, high carrier mobility, and narrow direct bandgap, have attracted much attention, especially in solar cells, photodetectors, and light‐emitting diodes (LEDs). However, whether it is organic iodide perovskite, organic–inorganic hybrid iodide perovskite or all‐inorganic iodide perovskite the stability of these iodide perovskites is still poor and the contamination is high. In recent years, scholars have studied more iodide perovskites to improve their stability as well as optoelectronic properties from various angles. This paper systematically reviews the strategies (component engineering, additive engineering, dimensionality reduction engineering, and phase mixing engineering) used to improve the stability of iodide perovskites and their applications in recent years.
