Nonsolar photovoltaic cells

For several interesting photovoltaic (PV) applications, the incident radiation is not sunlight (although it may be derived from sunlight). These nonsolar applications and the principles guiding cell design are reviewed. It is shown that much of the experience gained in designing and optimizing solar cells can be used. Cell design for luminescent sources, activated by thermal or chemical means, and for illumination by lasers is discussed. These special applications can have high conversion efficiency, in some cases over 50%.<
