We have employed a PAMAM dendrimer monolayer to reduce the surface roughness of sputter-deposited indium-tin oxide (ITO) films, which will be used in the fabrication of perovskite solar cells. A PAMAM-8 dendrimer monolayer was deposited by dip coating the substrates in 25 ml of a 1 μM PAMAM-8 ethanol solution before ITO deposition. ITO films of 150 nm thickness were then deposited onto the PAMAM monolayer using DC magnetron reactive sputtering. The surface roughness, sheet resistance, and transmissivity of the ITO films were optimized by varying the parameters of the sputtering process and post-deposition annealing process. An rms film roughness of < 1 nm, a sheet resistance of < 10 Ω/sq, and a transmissivity of > 90% at a wavelength of 400 nm to 700 nm were obtained after the optimization steps. A power dependence was seen on the ITO film surface roughness, with the lower powers yielding smoother films.
