High conductivity (～0.2scm-1) and wide band gap (～2.2eV) p-type microcrystalized silicon-carbide alloy (p-μ c-SiC:H) thin films were fabricated by PECVD method. The p-μc-SiC:H/p-a-SiC: H structure as window layer of solar cells improved obviously the contact characteristics of SnO2/P. Purthermore. the fill factor of single junction integrated solar cells with area of 10cm×10cm increased from below 0.70to 0.72.
