Deactivation of Interfacial Recombination Center for Thermally Stable Perovskite Solar Cells

from 1.032 to 1.19 V after introducing APTES, along with a certified PCE of 25.6%. Thermal stability tests at 85 °C for 1000 h following the ISOS-D2I protocol show that 82% of the initial PCE is retained by the deactivation approach.
