We study the electromagnetic response of individual spherical copper antimony disulfide (CuSbS2) nanoparticles and layers embedded with them for solar applications and near infrared (NIR) sensors using computational methods. We first calculate the single particle scattering and absorption efficiencies using Lorenz-Mie theory. The absorption and the total scattering efficiencies broaden and shift to longer wavelengths with increasing particle radius from 1 to 100 nm. We further investigate the response of multiple nanoparticles embedded in a thin layer at a low volume fraction using a Monte Carlo method. Our results demonstrate that with increasing particle size and scattering NIR transmittance is strongly suppressed and absorption and reflectance enhanced. The high absorption coefficient and solar-compatible band gap of CuSbS2 make it a good candidate for nanocrystalline solar cell and other NIR device applications.
