A system is provided. The system includes a thin film. The thin film includes a first material that absorbs light within a first band gap and passes a remaining portion of the light that is outside of the first band gap. The thin film is electrically connected to an intermediate electrical device. The thin film converts the light within the first band gap to electricity. The thin film provides the electricity to the intermediate electrical device. The system includes a solar panel that includes a second material that absorbs the remaining portion of the light passed by the thin film. The solar panel includes c-Si. The system includes a coupling between the solar panel and the thin film.
