Resumo

Perovskite solar cells (PSC) have been extensively studied over the past few years in both academia and industry. Despite their appeal as a low cost and ease processing PV-technology, PSC still rely on materials that are expensive, turning the large-scale production more challenging. In this work, polyaniline (PAni) and its derivative poly(o-methoxyaniline) are employed as hole transport material (HTM) in PSC, replacing the most explored HTM, spiro-OMeTAD. These very well established conducting polymers are doped with 4-dodecylbenzenesulfonic acid (DBSA) to enhance their conductivity. The correlation between the performance of the solar cells using doped and undoped conducting polymers and different metallic contacts are also evaluated. The best power conversion efficiency was 10.05% using doped PAni-DBSA with Au as contact, which is similar to the performance exhibited by our standard device using Spiro-OMeTAD as HTM. (AU)
