Stability Improvement of Perovskite Solar Cells for Application of CuInS(2) Quantum Dot-Modified TiO(2) Nanoarrays

[Image: see text] In this work, we developed a CH(3)NH(3)PbI(3) perovskite solar cell with CuInS(2) quantum dot-modified TiO(2) nanoarrays (TiO(2)–CuInS(2) QD-NAs) as a scaffold layer. Based on the suitable device configuration, we achieved improved power conversion efficiency (PCE) of 13.3%, which...

description [Image: see text] In this work, we developed a CH(3)NH(3)PbI(3) perovskite solar cell with CuInS(2) quantum dot-modified TiO(2) nanoarrays (TiO(2)–CuInS(2) QD-NAs) as a scaffold layer. Based on the suitable device configuration, we achieved improved power conversion efficiency (PCE) of 13.3%, which was 38.3% higher than that of the device without QD modification (8.2%). After exposure to air for 30 days, the TiO(2)–CuInS(2) QD-NA-based device possessed a PCE of 5.4%, being 41% of the original performance, which was far superior to that of TiO(2) nanoarray-based solar cells with a PCE of 1.1%. Our results showed that the crystallinity of perovskite, surface state, and interface for charge transport of TiO(2)–CuInS(2) QD-NA-based perovskites all remarkably improved, indicating the improved air stability for TiO(2)–CuInS(2) QD-NA-based solar cells.
