Area of Science:

• Materials Science
• Solid-State Chemistry
• Optoelectronics

Background:

• Conventional 3D perovskites are widely used in solar cells but face stability challenges.
• Low-dimensional-networked (LDN) perovskites, with 2D, 1D, or 0D structures, exhibit improved environmental stability.
• LDN perovskites offer unique properties like flexible crystal structures and lower ion mobility compared to 3D counterparts.

Purpose of the Study:

• To review variable ligands used in LDN perovskite synthesis.
• To compare the distinct properties of LDN perovskites with conventional 3D perovskites.
• To summarize research progress and mechanisms of LDN perovskites in optoelectronic devices.

Main Methods:

• Literature review of scientific publications on LDN perovskites.
• Analysis of material properties and device performance data.
• Comparative study of LDN and 3D perovskite characteristics.

Main Results:

• Variable ligands enable diverse LDN perovskite structures and tunable properties.
• LDN perovskites demonstrate robust stability against moisture and thermal stress.
• Applications in solar cells, LEDs, LSCs, and photodetectors show promising performance.

Conclusions:
