A practical perspective for chromatic orthogonality for implementing in photolithography

Abstract

Theoretically, it is more challenging to anticipate the conversion and selectivity of a photochemical experiment compared to thermally generated reactivity. This is due to the interaction of light with a photoreactive substrate. Photochemical reactions do not yet receive the same level of broad analytical study. Here, we close this research gap by presenting a methodology for statistically forecasting the time-dependent progression of photoreactions using widely available LEDs. This study uses NiS/ZnO in perovskite (MAPbI3) solar cells as an additive (5 volume %). The effect of monolithic perovskite solar cells (mPSCs) on forecasting the wavelength of LEDs has been carefully investigated using various characterization methods, including X-ray diffraction (XRD) and Transmission electron microscopy (TEM). The photocatalytic activity was analyzed by measuring the voltage produced. Various factors like selectivity, stability and sensitivity were also examined. This work provides a new perspective to validate NiS/ZnO photocatalysts for predicting the wavelength of different light sources and to apply in photolithography.

On photokinetics under polychromatic light

“…In this case, the reaction is a divergent depletion of the reactant ( ) by branched processes assuming, for instance, the reactivity of two separate but simultaneously irradiated functional groups within a single molecule. Here, it is considered that the SPM absorption covers only the absorption band of one of the functional groups but not the other ( Figure 5 ), which is a typical situation exploited for chromatic orthogonality ( Bochet, 2006 ; Corrigan and Boyer, 2019 ; Kumar et al, 2023 ). For our example, the increase of the selected SPM s’ absorption blocks one reaction step almost completely (e.g., that producing , corresponding to the reactant absorption band situated between 350 and 410 nm), which allows photoselectivity of the product ( ) emerging from the other reaction branch, which corresponds to the reactant absorption band situated between 310 and 350 nm (or vice versa for another set of SPM s whose absorption region overlaps that of ).…”
