Keywords: cesium lead bromide iodide perovskite solar cell interfacial engineering.They researched the compound: tert-Butyl 2-cyanoacetate( cas:1116-98-9 ).Application of 1116-98-9. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:1116-98-9) here.
All-inorganic cesium lead halide (CsPbX3) perovskites exhibit superior thermal stability compared to their organic-inorganic hybrid counterparts. The power conversion efficiency (PCE) of CsPbI2Br perovskite solar cells (PSCs) has been over 16%. However, high-temperature annealing limits the feasibility of their application in flexible devices. Here, low-temperature processed flexible CsPbI2Br PSCs are designed by introducing Al-doped ZnO (AZO) as an electron-transport layer and tert-Bu cyanoacetate (t-BCA) as a passivation layer. The thickness-insensitive AZO significantly enhances the quality of the perovskite films and the reproducibility of the PSCs. t-BCA can effectively passivate the trap states and suppress charge recombination of CsPbI2Br films as well. The as-optimized flexible CsPbI2Br PSCs exhibit a high PCE of 15.08% (with an active area of 0.1 cm2), which is one of the highest efficiencies for flexible all-inorganic PSCs. The devices show outstanding stability, retaining 93% of their original PCE after being stored for 60 days, and retaining 91 and 86% of the initial efficiency after continuously heating for 360 h at 85° and storing under 65% RH for 30 h, resp. In addition, the PSCs exhibit excellent mech. stability, and retain 85% of their original value after 1000 bending cycles at a curvature radius of 3 mm.
