"Light-trapping by wave interference in intermediate-thickness silicon solar cells": comment
Abstract:
The critiqued paper [Opt. Express3229795 (2024)10.1364/OE.530718] reports surprisingly impressive, simulated results well above conventional limits for silicon solar cells, using regular pyramidal texture with macroscopic periodicity (3.1 µm). Our high-resolution solutions show these are overestimates. They lack the resolution to accurately describe optical modes, with the fit to silicon's optical constants also problematic, giving a negative absorption coefficient within the modeled range. Zero impact upon results from this oversight suggests premature termination of simulations before light escapes from slow optical modes, inadvertently treating temporarily trapped light as absorbed.
