A thin perovskite semiconductor sits on top, with a bandgap of ~1.6 eV. It efficiently absorbs blue and green light (wavelengths 300–700 nm).
Crystalline silicon sits below with a bandgap of 1.1 eV, absorbing red and near-infrared light (wavelengths 700–1200 nm) that the perovskite lets through.
Electrons flow in series; perovskite's higher bandgap raises voltage, silicon adds current.
