摘要： A multi-junction power converter system illuminated by an incident light source includes a multi-layer stack having a plurality of junctions defined by materials having different bandgaps, with an upper junction having a higher bandgap, and junctions therebelow having smaller bandgaps. The upper junction absorbs more of the incident light, whereas lower junctions successively absorb less of the remaining incident light. The junctions below the upper junction are supplied with additional illumination that has been reemitted from previous cells due to photon recycling. Related devices and methods of operation are also discussed.
