lead iodide(PbI2) residue on the performance of perovskite solar cells
Perovskite solar cells (PSCs) have rapidly emerged as a revolutionary technology in the photovoltaic landscape, boasting impressive power conversion efficiencies that now rival conventional silicon. A seemingly minor detail in their fabrication, the presence of lead iodide (PbI2) residue within the perovskite film, has surprisingly become a central topic of debate and research. While often…
