“…MoO 3 is adequate to attain a high built-in potential and V oc because it can suppress interfacial reactions at the HTL/BHJ interface. MoO 3 nanoparticles (NPs) can be added at the interface between the active layer and the PEDOT:PSS to take advantage of the localized surface-resonance plasmon (LSRP) effect of NPs and the electronic structure of MoO 3 [ 96 ]. MoO 3 NPs increased the path length of the absorbed light and blocked the electrons flow to the anode, resulting in a higher J sc and FF, and thus a PCE of 4.11% was reached over a long period of 30 days [ 97 ].…”

Global energy demand is increasing; thus, emerging renewable energy sources, such as organic solar cells (OSCs), are fundamental to mitigate the negative effects of fuel consumption. Within OSC’s advancements, the development of efficient and stable interface materials is essential to achieve high performance, long-term stability, low costs, and broader applicability. Inorganic and nanocarbon-based materials show a suitable work function, tunable optical/electronic properties, stability to the presence of moisture, and facile solution processing, while organic conducting polymers and small molecules have some advantages such as fast and low-cost production, solution process, low energy payback time, light weight, and less adverse environmental impact, making them attractive as hole transporting layers (HTLs) for OSCs. This review looked at the recent progress in metal oxides, metal sulfides, nanocarbon materials, conducting polymers, and small organic molecules as HTLs in OSCs over the past five years. The endeavors in research and technology have optimized the preparation and deposition methods of HTLs. Strategies of doping, composite/hybrid formation, and modifications have also tuned the optical/electrical properties of these materials as HTLs to obtain efficient and stable OSCs. We highlighted the impact of structure, composition, and processing conditions of inorganic and organic materials as HTLs in conventional and inverted OSCs.

“…Thermally evaporated WO 3 has displayed high thermal stability in inverted PSCs. 21 Although a few studies have demonstrated the use of solution-processed MoO 3 in the production of efficient inverted and conventional PSCs, 26–29 processing solution-processed MoO 3 HTLs remains challenging and there have been few investigations of their stability.…”

“…The literature also reports a couple of approaches where a double anodic buffer layer has been applied to inverted cells. Kim et al describe an inverted ITO/ZnO/P3HT:PCBM/MoO 3 np/PEDOT:PSS/Ag cell, exhibiting decreased charge recombination and a 4.11% PCE compared with 3.70% without MoO 3 np layer . However, due to the good adaptability of P3HT:PCBM to any anode buffer material, the advantage arising from the additional MoO 3 np layer is not so determinant in this case.…”

Although organic solar cells have surpassed the 17% power conversion efficiency threshold, commercial modules efficiencies are only around 4–5%. One of the reason is the lack of effective solution‐processable hole transport materials that are a key element for the scale‐up on roll‐to‐roll printing equipments and the commercial development. Herein, a class of novel vanadium and molybdenum polyoxometallate salts are developed that, alone or in combination with a traditional poly(ethylene‐3,4‐dioxytiophene):poly(styrene sulfonate) (PEDOT:PSS) layer, can be used as anodic buffer layer in inverted polymer solar cells. These materials exhibit work function values around 5.8 eV that match well with highest occupied molecular orbital energies of typical polymer donors. They are tested with different widely used active systems, including PTB7:PC71BM, PV2000:PCBM, and PffBT4T:PC71BM. Vanadium and molybdenum polyoxometallate can be deposited from solutions and, contrary to PEDOT:PSS used alone, do not cause a drop of performances compared with evaporated molybdenum oxide (e‐MoOx); on the contrary, in the best cases they achieve similar performances to e‐MoOx. Slot‐die‐coated PV2000:PCBM solar cells on flexible substrate achieve a remarkable power conversion efficiency of almost 7.6%.
