Assessment of Molecular Additives on the Lifetime of Carbon-Based Mesoporous Perovskite Solar Cells

Perovskite solar cells have progressed very steadily, reaching power conversion efficiencies (PCE) beyond 20% while also improving their lifetimes up to 10,000 h. A large number of cell architecture and materials for active, transporting electrode layers been used, either in blends or nanostructured layers. In this article, a set perovskite designed, fabricated characterized with special focus on lifetime extension. The inclusion 5-amino-valeric acid iodide (5–AVAI) as interlayer methyl-amino lead-iodide (MAPI) has provided additional stability PCE > 10% T80 = 550 Experiments 1000 h at maximum point under continuous illumination simulator carried out (1 kW/m2, AM1.5G, equivalent more than six months outdoor locations such Southeast Spain, an average irradiation 1900 kWh/m2/year). addition molecular additives the bulk active layer ETL carbon not only allows better carrier transport, but increases by reducing ion migration within MAPI between different Engineered interfaces ZrO2 TiO2 contribute degradation.
