Metal nanomeshes are demonstrated as flexible transparent conductors with performance comparable to indium tin oxide. However, it is not known what the performance limits of these structures are in terms of transparency and sheet resistance. More importantly, the haze, which describes how much incident light is scattered by these structures, has not been studied. In this paper, the transmission, sheet resistance, and haze of metal nanomeshes are comprehensively studied to determine their fundamental performance limits as transparent conductors through simulations and experiments. Numerical simulations and analytical calculations are used to evaluate the tradeoffs and correlations between these three figures of merit. A strong correlation is found between haze and transmission, where structures with high transmission tend to have low haze and vice versa. Structures with a pitch above 1000 nm are beneficial for achieving transmission over 80% and larger thickness is favorable in reducing sheet resistance without significantly affecting transmission. Furthermore, metal nanomeshes are fabricated to verify simulation results. The haze may be primarily explained by Fraunhofer diffraction, but the spectral dependence of haze requires analysis with Mie scattering theory. The results should apply to all metal grid or grating‐like structures. The fundamental performance limits evaluated here are helpful for guiding engineering design and research prioritization.

“…Among all, CsPbI 3 PSCs with excellent optoelectronic properties and improved stability are becoming increasingly popular compared with organic–inorganic hybrid perovskites . Nevertheless, these cells usually show low short‐circuit current density ( J SC ), owing to insufficient sunlight, caused by the reﬂection at interfaces …”

Transparent conductive fluorine‐doped tin oxide (FTO) glasses play a vital role in perovskite solar cells (PSCs) for their high conductivity and outstanding transparent properties. However, among all optical characteristics (transmittance, reflectance, and scattering) for glass, the light‐scattering property (usually defined by the haze) is usually negligent. Herein, four kinds of glasses with different hazes for CsPbI3 PSCs are carefully studied. Obviously, by using optimal glass (haze of 5%, transmittance of 83%, and no antireflection layer), the short‐circuit current density (JSC) and power conversion efficiency (PCE) of the cell are enhanced for reducing the escape of light from the solar cell. Further characterization reveals that such improvement not only originates from the comprehensive effect of the scattering from the FTO glass but also the large contrast in the imaginary part of the refractive index and the surface roughness between each layer in the PSC. Meanwhile, the effect of the presence of antireflection films on light scattering is compared. It is also found that leakage current induced by haze glass is avoided for small‐area (0.09 cm2) PSCs usually fabricated in the laboratory.
