“…Numerous research on LNMO-based nanoparticles have been started to investigate their structural, magnetic, and optical capabilities, but the key challenge is obtaining them for use in actual devices. 19,20 In the context of PSCs, the perovskite absorber layer, which has a thickness of several hundred nanometers, is positioned between the electron-transport layer (ETL) and the holetransport layer (HTL). Following the absorption of light, the generation of carriers, namely, electrons and holes, occurs.…”
