Morphological and electrical properties of La0.8Ca0.1Pb0.1FeO3 perovskite nanopowder for NH3 and CO gas detection

Influence of Nanosemiconductor Materials on Thermal Stability of Solar Cells

“…However, the perovskite layers deposited on TNRAs suffer from low coverage and high defect density, and the “TNRAs/perovskite” interfacial contact is problematic. As a result, the photoelectric conversion efficiency and stability of TNRAs-based PSCs are still not ideal [ 3 ]. How to optimize the contact and energy level matching between the “TNRAs/perovskite” interface, passivate the defects of perovskite films, and further improve the performance of TNRAs-based PSCs has become an urgent problem to be solved as shown in Figure 1 .…”

Exposure Surface Active Sites of Perovskite‐Type LaFeO3 Gas Sensors by Selectively Dissolving La Cations for Enhancing Gas Sensing Properties to Acetone

“…for sensing SO 2 , [23] CO, [24] formaldehyde, [25] and acetone. [26] However, pure perovskites usually exhibit unsatisfactory gas sensing performance, one of the main reasons being the low specific surface area resulting in too few active sites.…”

“…Perovskite LaFeO 3 , as a typical P‐type semiconductor, has attracted much attention and research in the field of catalysts, electrode materials, and gas sensors. [ 20–22 ] For gas sensor applications, perovskite LaFeO 3 has shown great potential for sensing SO 2 , [ 23 ] CO, [ 24 ] formaldehyde, [ 25 ] and acetone. [ 26 ] However, pure perovskites usually exhibit unsatisfactory gas sensing performance, one of the main reasons being the low specific surface area resulting in too few active sites.…”
