The interface VOC loss between the active layer and hole transport (HTL) of lead sulfide colloidal quantum dot (PbS-CQD) solar cells is a significant factor influencing efficiency improvement PbS (PbS-CQDSCs). Currently, most advanced adopt organic P-type HTLs (PbS-EDT) via solid-state ligand exchange with 1,2-ethanedithiol (EDT) on CQD top layer. However, EDT unable to altogether remove initial oleic acid from surface, its high reactivity leads cracks in HTL film caused by volume contractions, which inevitably results loss. These flaws prompted this research develop method involving hybrid using 3-mercaptopropionic (MPA) 1,2-EDT (PbS-Hybrid) overcome these drawbacks indicated that new strategy improved quality benefited enhanced passivation surface better alignment energy levels, average PbS-Hybrid devices increased approximately 25 mV compared control devices. With VOC, power conversion (PCE) 10%, highest PCE reaching 13.24%.

In this work, three polymerized small-molecule acceptors (PSMAs) (namely, PBTP-α, PBTP-β, and PBTP-m) based on distinct building blocks are developed to investigate the influence of regioisomerism terminal group units (TCN-α TCN-β) physicochemical, photoelectric, photovoltaic properties PSMAs. Comparative analysis reveals that PBTP-α exhibited red-shifted absorption, enhanced intramolecular charge transfer effects, stronger crystallinity, denser molecular stacking compared regioregular PBTP-β regiorandom PBTP-m. By utilizing PM6 as polymer donor, PBTP-α-based all-polymer solar cell (all-PSC) achieves a higher power-conversion efficiency (PCE) 8.17% with PBTP-β- (5.99%) PBTP-m-based (6.16%) devices.
