By using various advanced characterization methods, we have studied the relationship between optoelectronic properties, chemical composition, and structure of p-type µc-SiOx:H deposited by plasma enhanced chemical vapor deposition (PECVD). For a wide range of compositions with varying oxygen content, we show that the dominant components are Si and a-SiO2, while the fraction of suboxides is minor. The μc-SiOx:H material with sufficient oxygen content (x = 0.35) exhibits an enlarged optical gap E04 > 2.2 eV and sufficiently high dark conductivity >10−6 S cm−1; the crystalline silicon fraction has a filament-like shape (with a typical width of around 10 nm) forming a branch-like structure elongated in the growth direction over several hundreds of nanometers}, cin = {IEK-5}, ddc = {530}, cid = {I:(DE-Juel1)IEK-5-20101013}, pnm = {121 - Solar cells of the next generation (POF3-121)}, pid = {G:(DE-HGF)POF3-121}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000385222900024}, doi = {10.1002/pssa.201533022}, url = {https://juser.fz-juelich.de/record/809697}, }
