Astronauts aboard the Space Station are charged up these days, thanks in part to Sheila Bailey's hard work. The senior scientist with the Photovoltaic and Space Environment Branch of NASA Glenn Research Center at Lewis Field in Cleveland, OH is one of the several NASA scientist that helped develop the two 38-ft long x 239-ft wide solar panels installed on the Space Station this winter.
The new solar cells help improve the longevity of the panels thanks to improvements in the cell. The new cell structure coating is made of gallium-indium phosphate on gallium arsinide on germanium that resists oxidation. Previous versions of solar cells used silicon oxide coatings and silver interconnects that degraded in the upper-atmosphere oxygen. The new panels contain 66,000...
