We have applied double p -type amorphous silicon-carbide (p-a-SiC:H) layer structures to pin-type protocrystalline silicon (pc-Si:H) multilayer solar cells. The less-pronounced initial short-wavelength quantum efficiency variation against the biased voltage and the wide overlap of dark current-voltage (JD -V) and short-circuit current-open-circuit voltage (Jsc - Voc) characteristics prove that the double p-a-SiC:H layer structure successfully reduces recombination at the pi interface. Therefore, we achieved highly stabilized efficiency of 9.0% without any backreflector. © 2005 American Institute of Physics.
