Gallium (GaAs/Ge) and Indium Phosphide (InP) solar cells were subjected to 1 MeV electron irradiation, to fluences of 1[times]10[sup 16] electrons/sq cm. Attempts at recovery included thermal annealing, alone, and with an applied forward bias current, and injection :// Lasers can be used to transmit power to photovoltaic cells. Solar cell efficiencies are enhanced significantly under monochromatic light, and therefore a laser beam of proper wavelength could be a very effective source of illumination for a solar array operating at very high efficiencies.

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. The InP cells were irradiated with 27 MeV electrons to a given fluence, and tested for ://

Indium phosphide solar cells Abstract: The ideal solar cells for use in space have a high power to mass ratio and a high resistance to radiation.
To date, flat panels using cells based on single crystal silicon or gallium arsenide have been used on space flights, although development programmes have considered the use of cells based on other Herein, through delicately designing and engineering the van der Waals heterostructure between graphene and indium phosphide (InP), which has a suitable bandgap of eV for solar energy conversion, we have achieved graphene/p-InP solar cells with power conversion efficiency (PCE) of % under AM G :// Compared with the widely used Si, indium phosphide (InP) has a direct bandgap of eV, which locates at the optimum energy range for solar energy conversion.

Light falls upon the upper surface, is absorbed, and generates electron-hole pairs which are separated by the electric field associated with the depletion region. Pulko, N. Pearsall, and A. Hurst "Simulation of the indium-phosphide-based solar cell", Proc.
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.
Here we enhance the absorption in indium phosphide (InP Gallium indium phosphide is a "ternary" compound, in which two elements from group III are alloyed with one from group V.

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.
