Abstract

This work refers to the fabrication of hybrid solar cells based on porous silicon (PS) filled with copper phthalocyanine (CuPc) to form GZO/CuPc-PS/Si/Al structure. We used n-type Si since photoinduced charge transfer from CuPc to Si is observed only for n-type Si. The characteristic 100% peak at 6.8 degrees 2 theta from XRD confirms that the CuPc coating on PS exists in alpha-CuPc polymorph. The systematic increase in FWHM of XRD peak at 69.1 degrees 2 theta and red-shift of LO phonon Raman spectra indicate a progressive reduction of Si nanocrystallites size with increasing etching time and the estimated size agrees well with atomic force microscopic images. The FTIR results confirm the formation of alpha-CuPc polymorph and it is also corroborated well with XRD and Raman results.
