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 000809697 536__ $$0G:(DE-HGF)POF3-121$$a121 - Solar cells of the next generation (POF3-121)$$cPOF3-121$$fPOF III$$x0 000809697 588__ $$aDataset connected to CrossRef 000809697 7001_ $$0P:(DE-Juel1)130263$$aLambertz, Andreas$$b1$$ufzj 000809697 7001_ $$0P:(DE-Juel1)130269$$aMoll, Sandra$$b2$$ufzj 000809697 7001_ $$0P:(DE-HGF)0$$aBär, M.$$b3 000809697 7001_ $$0P:(DE-HGF)0$$aStarr, D.
