Abstract

Abstract : In this work, we introduce P3HT (poly(3-hexylthiophene-2, 5-diyl)) as an efficient hole transport material (HTM) for lead-free Cs3 Sb2 I9 perovskite-inspired solar cells. Abstract : In this work, we introduce P3HT (poly(3-hexylthiophene-2, 5-diyl)) as an efficient hole transport material (HTM) for lead-free Cs3 Sb2 I9 perovskite-inspired solar cells. The P3HT doubles the power conversion efficiency (PCE) of the solar cells (PCE = 2.5% for the champion device) by improving all of the figures of merit: the fill factor, open-circuit voltage, and the short-circuit current. The maximum power point tracked efficiency was 2.0%, which is the highest so far reported for this type of solar absorber. The discovery of an efficient HTM for Cs3 Sb2 I9 is an important step in advancing safer lead-free perovskite-inspired solar cells.
