AI Article Synopsis
- The study focuses on using magnetron-sputtering to create controlled metal nanoparticles, specifically Ag/MgO, for improved perovskite solar cells.
- The Ag nanoparticles are deposited on a glass/FTO/TiO substrate, which is essential for the solar cell's front electrode, and their structural and oxidation resistance is thoroughly examined.
- Optimizing the nanoparticle coverage leads to a significant 5% increase in power conversion efficiency, achieving a total efficiency of 17.8% for the engineered solar cells.
Article Abstract
Nanocluster aggregation sources based on magnetron-sputtering represent precise and versatile means to deposit a controlled quantity of metal nanoparticles at selected interfaces. In this work, we exploit this methodology to produce Ag/MgO nanoparticles (NPs) and deposit them on a glass/FTO/TiO substrate, which constitutes the mesoscopic front electrode of a monolithic perovskite-based solar cell (PSC). Herein, the Ag NP growth through magnetron sputtering and gas aggregation, subsequently covered with MgO ultrathin layers, is fully characterized in terms of structural and morphological properties while thermal stability and endurance against air-induced oxidation are demonstrated in accordance with PSC manufacturing processes. Finally, once the NP coverage is optimized, the Ag/MgO engineered PSCs demonstrate an overall increase of 5% in terms of device power conversion efficiencies (up to 17.8%).
