Molecular doping has become a valuable technique for enhancing the efficiency of high-performance organic photovoltaic systems (OPVs). However, number known dopant molecules, especially n-type ones, that enhance PCE OPVs remains limited. In this study, two dopants, ethyl viologen (EV) and methyl (MV), are synthesized incorporated into ternary PM6:BTP-eC9:PC71BM bulk heterojunction (BHJ) OPVs. Both dopants found to OPV performance, yielding maximum values 19.03% 18.61%, respectively. We show EV MV function as microstructure modifiers, π–π stacking while increasing absorption coefficient BHJs. Moreover, n-doping balances carrier mobility lifetime reducing bimolecular recombination. Our results demonstrate potential improve performance highly efficient levels beyond those achievable by pristine BHJ.

Copper(I) thiocyanate (CuSCN) is a wide bandgap and solution-processable p-type semiconductor with tremendous potential for large-area optoelectronic applications. In this work, chlorine-doped CuSCN (Cl2–CuSCN) was utilized to form hole transport layer (HTL) different organic solar cells (OSCs) inverted perovskite (PSCs). Chlorine doping into thin films found improve the device performance of OSCs, level comparable that PEDOT:PSS-based OSCs. Notably, PSCs Cl2–CuSCN showed better than those pristine or PSC devices. Moreover, Cl2–CuSCN-based OSCs also reveal significantly stability Our results show how act as universally applicable HTL emerging cell technologies, improving both stability.

Interface layers used for electron transport (ETL) and hole (HTL) often significantly enhance the performance of organic solar cells (OSCs). Surprisingly, interface engineering extraction has received little attention thus far. By finetuning chemical structure carbazole-based self-assembled monolayers with phosphonic acid anchoring groups, varying length alkane linker (2PACz, 3PACz, 4PACz), these HTLs were found to perform favorably in OSCs. Compared archetypal PEDOT:PSS, PACz exhibit higher optical transmittance lower resistance deliver a short-circuit current density fill factor. Power conversion efficiencies 17.4% have been obtained PM6:BTP-eC9 as active layer, which was distinctively than 16.2% PEDOT:PSS. Of three derivatives, new 3PACz consistently outperforms other two monolayer OSCs different state-of-the-art nonfullerene acceptors. Considering its facile synthesis, convenient processing, improved performance, we consider that is promising layer widespread use
