| Abstract Scope |
For the hybrid organic-inorganic systems, cesium-based triple cation perovskite solar cells (Cs₀.₀₅FA₀.₇₉MA₀.₁₆PbI₂.₄₅Br₀.₅₅) have recently received a great deal of attention in view of their greater stability compared to the historically significant methyl ammonium lead iodide (MAPbI3) absorber, given the vulnerability of the latter to moisture, oxygen, and ultraviolet radiation. In this work, we have studied the long-term stability of Cs₀.₀₅FA₀.₇₉MA₀.₁₆PbI₂.₄₅Br₀.₅₅ under various stress conditions to accelerate degradation which provide clues into enhancing their stability further. The cesium-based triple cation absorber is integrated into the n-i-p solar cell architecture with gold as the collector electrode, and the stability was gauged using in-use testing with maximum power point tracking, as well as in elevated thermal ambients. |
