Since innovation, different dye-sensitized solar cells
(DSSCs) have endeavored with additional components to escalate
the efficiency, cost-effectiveness and long-term stability. Various
approaches have been executed to reduce the amount of costly
platinum (Pt) used in DSSCs and/or to explore cheaper alternatives
to Pt. In this work, cheaper elements based quaternary chalcogenide
alloy; Cu2ZnSnS4 (CZTS) has been projected as a prominent counter
electrode (CE) candidate to Pt in DSSCs. The CZTS thin film has been
developed by an in-situ synthesis employing a hydrothermal
technique and further evaluating various physicochemical
characterization. Our results manifest that using the CZTS CE, a
power conversion efficiency (PCE) of 4.3% was exhibited for TiO2
based photoanode. The highest PCE of 6.5% was achieved for
BaSnO3 based photoanode, a promising alternative oxide to TiO2
photoanode. This work further signifies a unique combination of newly
developed BaSnO3(BSO)-CZTS DSSCs, could be a promising
competitor to TiO2-Pt DSSCs.
