We present stellar evolution calculations for Population III stars for both single- and binary-star evolutions. Our models include 10- and 16.5-M ⊙ single stars and a 10-M⊙ model star that undergoes an episode of accretion resulting in a final mass of 16.1 M ⊙. For comparison, we present the evolution of a solar heavy element abundance model. We use the structure from late-stage evolution models to calculate simulated supernova light curves. Light curve comparisons are made between accretion and non-accretion progenitor models, and models for single-star evolution of comparable masses. Where possible, we make comparisons to previous works. Similar investigations have been carried out, but primarily for solar or near-solar heavy metal abundance stars and not including both the evolution and the supernova explosions in one work.
