Stability and performances of amorphous silicon multijunction and single junction solar cells

The reliability of hydrogenated amorphous silicon multijunction solar cells was investigated. The n/p interface is thought to play an important role in light‐induced effect of multijunction solar cells. Blocking barriers which promote carrier recombination at n/p interface were applied here. As compared with ordinary solar cell, this solar cell shows an excellent stability for light exposure. The stability for thermal treatment is also discussed.
