Abstract

The effect of N₂ plasma, O₂ plasma, and electron beam surface treatments on ITO-coated glass substrates for organic solar cells has been studied. The efficiency of ITO/PEDOT:PSS/CuPc/C₆₀/Al solar cells built on N₂ plasma-treated ITO substrates was nearly double that of cells built on untreated substrates. This improvement is attributed to an increased hydrophilic nature of the surface, decreased surface roughness, and a slight decrease in the In/Sn ratio in the ITO films
