What is the history of space photovoltaics (PV)?
The history of space photovoltaics (PV) is in many ways the history of PV. However, the early development of the photovoltaic solar cell, or “solar battery” as it was called by the inventors at Bell Labs, did have visions of numerous terrestrial uses for the new source of electrical power back in 1954.
Which space station used GaAs solar cells?
Although it was launched before the ISS, the Mir modular space station that was assembled in LEO 1986 to 1996, and operated until 2001 by the Soviet Union and later by Russia, actually used GaAs solar cells; see Fig. 1.12 .
What is space photovoltaic technology?
These space activities require a cost-effective, sustainable source of onboard energy, such as solar photovoltaics. Traditionally, space photovoltaic technology is based on group III–V materials (such as gallium arsenide with indium phosphide and germanium for multi-junction cells) due to their high performance and radiation resistance.
What is the history of space PV?
We have emphasized the impact that it continues to have on the exploration and development of space. Clearly, the history of space PV is in many ways the history of PV. In fact, the development of space solar power systems drove much of the development of early PV solar cells and arrays.
How much does a space photovoltaic cost?
Traditionally, space photovoltaic technology is based on group III–V materials (such as gallium arsenide with indium phosphide and germanium for multi-junction cells) due to their high performance and radiation resistance. However, they are costly (>US$70 W –1 or >US$10,000 m –2).
Why did the International Space Station not charge?
For example, the International Space Station (ISS) did not charge up to expected levels because of its closely spaced solar cells, wrap-through interconnects, and coverglass overhangs, which serve to choke off electron collection and prevent the concomitant negative charging that would otherwise occur on its high voltage solar arrays.
