Indium phosphide is used to make semiconductors,injection lasers, solar cells, photodiodes, and light-emittingdiodes. Indium phosphide was nominated for study because of its widespread use in the microelectronics industry, the potential for worker exposure,and the absence of chronic toxicity data.

Alta Devices, of Sunnyvale, Calif., which makes solar cells for unmanned aerial vehicles, announced in April that a dual-junction device made of gallium-arsenide and indium-gallium-phosphide had   from radiation damaged indium phosphide diffused junction solar cells. This involves the illumination of damaged solar cells with a continuous wave laser to produce a moderate heating and a large forward-biased current.

SPIE   Photovoltaic cells based on arrays of semiconductor nanowires promise efficiencies comparable or even better than their planar counterparts with much less material. One reason for the high efficiencies is their large absorption cross section, but until recently the photocurrent has been limited to less than 70% of the theoretical maximum.

Indium phosphide (InP) solar cells have demonstrated better radiation resistance than gallium arsenide (GaAs) and silicon (Si) cells (refs. 1 and 2), but the high cost of InP wafers inhibits their use for large space power applications.
