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
