Atmospheric-pressure plasma treatments applied on titanium dioxide layer for Sb2S3 solar cells applications

This work presents the effect of atmospheric-pressure plasma (APP) treatment on mesoporous TiO2 (mp-TiO2) layers for antimony sulfide (Sb2S3) solar cells. For this work, it was prepared heterojunctions of antimony sulfide (Sb2S3) thin films solid solution as the absorbing materials and cadmium sulfide (CdS) as a sensitized layer deposited by the successive ionic layer adsorption and reaction (SILAR) technique, the Sb2S3 was obtained by chemical bath deposition (CBD). The photovoltaic characteristics of the solar cells with APP treatment showed a power conversion efficiency (PCE) of 0.54% to 1.04% with APP 0- and 60-seconds treatment, respectively.
