Abstract
CZTS material is seen as a very potential replacement for toxic
CIGS, and CIS material as a thin-film solar cell absorber layer. Because
of its extraordinary light absorption capacity and generation of
electron-hole pairs, CZTS has been implemented as a thin-film solar
cell. Research is going on over the last decade on increasing the
efficiency of the CZTS solar cell. Different structural and material
properties have been experimentally altered to achieve higher
efficiency. But even after several attempts the single junction CZTS
solar cell has not achieved an efficiency of more than 13%. In this
article, a detailed review is done of the developments that have taken
place and the future scope of the CZTS thin-film solar cell (TFSC). From
its evolution, materials preparation, fabrication process, TFSC design,
and defects in CZTS to its implementation as a solar cell are discussed
in this manuscript.
