Table : Input parameters used in pvTrace v2.1sv simulations (based on experimental data from the literature) for bulk square LSCs based on LR305 doped in poly(methyl methacrylate) (PMMA). We note that many of the studies did not specific the background absorption coefficients, and most of those that did, reported a constant value rather than a more realistic wavelength-dependent response. Instead of importing the spectrum used in the studies (which was not available), a Planck distribution (Equation S3) at 5800K was used for the shape of the light source spectrum. Because only 10,000 -100,000 rays are generated, a Planck distribution is sufficient to mimic solar radiation or a solar simulator. The Planck distribution is defined as:
