Abstract: Due to the possible consequences of the greenhouse effect for future generations, solar energy has emerged as a promising alternative due to its great energy potential, especially for Brazil, which is in a privileged geographical position on the planet. The aim of this study is the deposition of Pt/FTO on the counter electrode of dye-sensitized solar cells (DSSC), as there are few studies in the literature on this area, and evaporation deposition is normally used. The counter electrode used was platinum deposited on FTO by chronoamperometry. The tests were performed in triplicate, at 90, 600 and 1800 seconds on AutoLab equipment, model PGSTAT302N. The solar cell was assembled in a sandwich format, with an active area of 0.23 cm2, so we attempted to develop a method for electrodeposition of platinum, using chronoamperometry, obtaining a PCE of 0.517% for deposition in 600 seconds.
