The Power Conversion Efficiency (PCE) of Perovskite Solar Cells (PSC) increased over 600% in 10 years, and PCE higher than 25% was achieved. However, such devices suffer from low stability, poor reproducibility, and high hysteresis in the current vs. voltage curve, which limits their commercialization. Under this perspective, techniques for passivation of charge traps, and suppression of ion mobility display a central role. Here, we present the preliminary results and insights about a class of molecules designed, synthesized, and used as a passivating agent for PSC. We tested the molecule’s performance in its neutral and protonated state. The initial studies point out an improvement in the open-circuit voltage (VOC) and short circuit current (JSC), which are attributed to the passivation of perovskite surface traps.
