摘要：
In this paper is presented the influence of precursor concentration on the structural and optical properties of CoxOy thin films synthesized in the pores of PVP by chemical bath deposition technique. XRD analysis results revealed the films to be cobalt oxyhydroxide, CoO(OH) nanocrystals of size range 28.04nm - 65.65nm. Studies of the optical properties using absorption spectra in UV-VIS-NIR regions showed that the optical parameters (including constants) increased with increase in precursor concentration in an irregular manner. The energy band-gap of the films ranged from 2.70eV to 3.62eV which makes them possible materials for use as window layer in solar cell.
