A photovoltaic electrode is made by the following steps: (a) depositing on a substrate a dispersion comprising powdered semiconductor particles in a dispersion medium; (b) removing the majority of the dispersion medium to leave the powdered semiconductor particles in a deposition layer on the substrate; (c) creating a plasma using microwave energy excitation; (d) exposing the deposition layer to said microwave-excited plasma for a sufficient time to sinter the nanoparticles thereby adhering them to the substrate; and (e) absorbing a dye into said sintered deposition layer. The electrode thus obtained exhibits improved performance relative to conventional sintered electrodes.
