Hole‐Transporting Materials In article number 2000109 , Zong‐Xiang Xu and co‐workers determine that the highest power conversion efficiency of perovskite solar cells based on a poly(3‐hexylthiophene)/gold nanorod (P3HT/AuNR) composite hole‐transporting material reaches up to 16.88%, which is an increase of 26% from that of a pristine P3HT‐based device (13.40%). The enhanced performance is attributed to the higher carrier mobility and increased light utilization efficiency induced by the addition of AuNRs with localized surface plasmon resonance effect in the polymer matrix.
