This review explores different paths to replace traditional HTMs, it discusses recent advancements in conjugated organic-HTMs, organic-SAMs and polymeric-HTMs, aiming to improve the efficiency and stability of lead and tin-based PSCs.
This review highlights the most relevant works on phthalocyanines, porphyrins and other porphyrinoids as components of perovskite solar cells from the last four years acting as hole transporting materials, additives, and interlayers.
This study challenges HOMO level engineering approaches to SAM design by demonstrating that this leads to reduced quasi-Fermi level splitting in the perovskite and thus lower open-circuit voltage and performance.
A multi-level theoretical protocol is developed to characterize the charge transport of a novel indoloindole-based hole-transporting material. The implications of molecular shape, dynamic disorder and amorphousness on the hole mobilities are discussed.
Photovoltaic (PV) materials, especially organic and perovskite solar cells are effective candidates for meeting the rising global energy demand.
