EPD method for thin films on solar cells

Electrophoretic deposition (EPD) deposits thin films, with simple yet efficient deposition of nanomaterial. This work deposited photoanodes of zinc oxide on fluoride-doped tin oxide (FTO) decorated with tin chloride, changing the applied tension between 30 V, 40 V, and 50 V. Afterwards, the sandwiched photoanodes (Sn/ZnO/FTO) were assembled on dye solar cells, for photovoltaic tests. The results demonstrated a better short current density for the 30 V (10 % Sn/ZnO), at about 6.32 mA/cm2, and incident photocurrent efficiency (IPCE) of 12.5 %.
