Raman spectra of i-type μc-Si:H layer of the cells. The Raman spectra of i-type μc-Si:H of the cells. The red line and line of black squares stand for the original measured data, and the green lines stand for the Gaussian fitting data. The Raman imaging microscope is equipped with a 514-nm wavelength line of an Ar laser.
