CsI, PbI₂, LiF, CsCl, dimethyl sulfoxide (DMSO), chlorobenzene, and poly (sodium 4-styrenesulfonate) [PSS-Na; average M_w (weight-average molecular weight) ~70,000] were purchased from Sigma-Aldrich. 3TPYMB, PhBAI, 2-NMAI, and PVK (average M_w > 100,000) were purchased from Xi’an Polymer Technology Corp. TFB and 2-[2-[2-(2-aminoethoxy)ethoxy]ethoxy]ethanamine (ODEA) were purchased from 1-Material and Aladdin, respectively. The m-PEDOT:PSS solution was a mixture of normal PEDOT:PSS (AI 4083) aqueous solution with PSS-Na aqueous solution (100 mg/ml) by a volume ratio of 3:1, as well as with CsCl (15 mg/ml). The BC powder was dissolved in DMSO solvent with a concentration of 10 mg/ml; to introduce passivators, CsAc or CsFa (5 mg/ml) was separately added in the BC solution. The quasi-2D perovskite (2-NMA_0.4PhBA_0.6)₂CsPb₂I₇ precursor was prepared by dissolving PhBAI, 2-NMAI, CsI, and PbI₂ in a molar ratio of 0.6:0.4:0.75:1 in DMSO under continuous stirring overnight at 40°C while keeping the Pb²⁺ concentration at 0.2 M. Meanwhile, ODEA was added into DMSO with a concentration of 20 μl/ml, and the solution was added in perovskite precursor with a concentration of 50 μl/ml.

The polyethylene terephtalate (PET) substrate Polifoil Bias is purchased from Policrom Screen. Ag 5000, DuPont Silver Ink is used for printed interconnects. Carbon ink 7102 printing paste from DuPont is used for the electrode contacts. Insulating ink (5018, DuPont) is used for electrode isolation. PQ-10, PSSNa, and BBL were purchased from Sigma-Aldrich and used as received. The P(g42T-T) and BBL inks are fabricated through a solvent exchange method. P(g₄2T-T) (30 mg) dissolved in chloroform (15 mL) is added dropwise to isopropanol (75 mL) under high speed stirring (1500 rpm) to obtain bright blue nanoparticles of P(g₄2T-T). BBL (30 mg) dissolved in methanesulfonic acid (15 mL) is added dropwise to isopropanol (75 mL) under high-speed stirring (1500 rpm) to obtain dark purple BBL nanoparticles. The P(g₄2T-T) and BBL nanoparticles are respectively collected by centrifugation (5000 rpm, 30 min) and washed in IPA six times until neutral. The neutral P(g₄2T-T) and BBL nanoparticles are re-dispersed in IPA to obtain dispersion inks (about 0.006 mg/mL for P(g₄2T-T) and 0.1 mg/mL for BBL)^{34 ,46 (link)}.

Pt-Ir Alloy and PEDOT:PSS Coatings

(1) Pt-Ir alloy with nanoscale surface textures: Electrochemical deposition of Pt-Ir used a mixed plating bath of ammonium hexachloroplatinate and hexachloroirridate. The details of the plating solution and deposition processes appear elsewhere.^{[22 ]} Immersing bare electrode surfaces in the plating bath followed by application of a controlled electrochemical potential (Gamry Reference 600 in a 3-electrode system) caused chemical reduction of metal ions in solution to metal alloys on the electrode surfaces. The deposition conditions define the morphology and composition of the resulting coatings. (2) PEDOT:PSS coatings: 0.2g of EDOT (Sigma-Aldrich) added to 200 mL deionized water, stirred overnight for complete dissolution, followed by 0.4 g of PSSNa (Sigma-Aldrich) yielded the solution for electro-polymerization. A potentiostat (Gamry Reference 600) controlled the electro-polymerization processes in a 3-electrode configuration. Immersing the selected electrodes on the 3D-MIM into the solution and applying a constant voltage (1.1 V to Ag/AgCl reference electrode) for 10 minutes, formed the desired coating, as evidence by a change in the color of the electrode surface from gold to dark blue/black. For values above a certain level, the thicknesses of the coatings has little effect on the electrochemical impedance.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
