Photovoltaic devices


Abstract Structural properties and solar cells performance of sputter grown sub-micrometer thick ( 600 nm) Cu2ZnSnS4 (CZTS) films are investigated for low cost and large scale photovoltaic deployment. The \{CZTS\} films are deposited using single quaternary stoichiometric target at room temperature. X-ray diffraction, micro-Raman spectroscopy, and scanning electron microscopy measurements were carried out to investigate the structural property and secondary phase formation. The intense phonon peak at 334 cm−1 in the visible Raman spectra confirms the deposition of single phase \{CZTS\} films. CZTS-based thin film solar cells show excellent performance with open circuit voltage  600 mV and over all cell efficiency of  3.07%, exhibiting commercial potential toward large scale fabrication of photovoltaic devices.
