Here we study photovoltaic properties of GaInPNAs based quantum well and superlattice solar cells that are strain balanced or lattice matched to Si and evaluate their potential toward the development of high efficiency tandems operating in conjunction with a silicon bottom cells.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
