Directional Transformation of Heterometallic Oxo Clusters: A New Approach to Prepare Wide‐Bandgap Cathode Interlayers for Perovskite Solar Cells

“…The SnO 2 are typically used as the ETM to fabricate highly efficient PSCs [11–13] . However, the defect concentration at the interface of perovskite and ETMs is about 100 times than that of perovskite film, thereby destroying the cell performance and stability [6] .…”

Anti-corrosion strategy to improve the stability of perovskite solar cells

“…4,5 In recent years, metal halide perovskites have been a hotspot in semiconductor materials due to their excellent optoelectronic properties, easy processing capability, tunable bandgaps, and high tolerance to defects. [6][7][8][9][10][11][12][13][14][15] Perovskite solar cells (PSC) have shown remarkable progress in recent years with rapidly increasing power conversion efficiencies (PCEs) of up to 25.8%, 16 approaching that of the state-ofthe-art PCE of 26.81% obtained for crystalline-silicon solar cells. However, metal halide perovskites (MHPs) can degrade when exposed to humidity, oxygen, temperature, electrical bias, illumination, and stress, [17][18][19][20][21][22][23][24][25] which hinders the commercialization of the resultant photovoltaic technology.…”

Synergetic Passivation of Metal‐Halide Perovskite with Fluorinated Phenmethylammonium toward Efficient Solar Cells and Modules

“…[5][6][7] To minimize the defects and suppress the recombination reactions, many strategies including surface passivation, composition engineering, perovskite film deposition optimization have been proposed, and great progress have been achieved in recent years. [8][9][10] The surfaces and grain boundaries are the places where defects are most easily formed, and passivation of the surface defects is always the most important task in any type of solar cells. [11] So far, a vast number of molecules have been developed as passivation agents and utilized as interlayers at the interfaces.…”
