TECSTAR Sets Record of 27% AMO Efficiency

July 12, 1999 by Jeff Shepard

TECSTAR (City of Industry, CA) announced it has set a record 27 percent AMO efficiency at the company's Applied Solar Division (ASD) with the firm's Cascade multijunction solar cell technology. TECSTAR has been developing multijunction solar cells since 1992, and emphasizing Cascade multijunction technology since 1995. The improved Cascade triple junction solar cell technology verifies the device modeling and process controls, according to TECSTAR. This is expected to translate into a 33 percent increase in available satellite power over single junction gallium arsenide (GaAs) for their customers.TECSTAR also says that their technology is now achieving lot averages between 23 and 24 percent, with best cell efficiencies approaching 26 percent. To date, TECSTAR has produced more than 120,000 Cascade brand name solar cells.
