Abstract Copper zinc tin sulfide, Cu 2 ZnSnS 4 (CZTS) is being considered a viable option for counter electrode due to its abundance, cost-effectiveness, catalytic activity, and other advantageous properties. However, CZTS has low electron transport capabilities, shortcoming that can be addressed by combining it with high mobility carbon nanomaterials. Nitrogen-doped multi-walled nanotubes (N-MWCNTs) exhibit higher conductivities than their pristine counterparts. This improvement attributed...
