“…Different commercial grades of PEDOT:PSS and additive solvent EG were used to form a hybrid PEDOT:PSS (PH 1000:Al 4083) layer tested as an HTL and anode electrode for inverted OSCs based on P3HT:PCBM [ 267 ]. An OSCs based on PTB7-Th:PC 71 BM was built using a hole-transport double layer made of pyridine-based tetrathiafulvalene derivative (TTF-py) on PEDOT:PSS [ 268 ]. This modification resulted in an increased short circuit current (J sc ) of 17.19 mA cm −2 and a PCE of 9.37%.…”

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.

“…46 Liu et al have reported the application of pyridine-based tetrathiafulvalene derivatives as the interfacial modifier on the surface of PEDOT:PSS film for the construction of well performing polymer solar cells. 47 These studies reveal that pyridine is a good building block for enhanced charge transport and interfacial interaction to obtain efficient and stable PSCs. However, study of the pyridinefunctionalized HTMs in inverted PSCs has not been very sufficient until now; in particular, dopant-free pyridine-based HTMs for inverted PSCs have not been reported to the best of our knowledge.…”

New building blocks of cores and periphery groups for organic hole-transporting materials (HTMs) have been paid much attention for recent development in perovskite solar cells (PSCs). In this work, we applied facile synthesis to join a 2,4,6-triarylpyridine building block for new HTMs based on a pyridine core by cheap industrial initial materials. The three small molecules, namely, D104, D105, and D106, were used in the pristine state. To the best of our knowledge, pyridine-cored dopant-free HTMs have not been reported in PSCs. The changing periphery 4-methoxyphenyl and bis(4-methoxyphenyl)amine groups formed different Y-shapes. Under 1 sun conditions, the devices achieved an increased power conversion efficiency (PCE) of 16.28%, 17.40%, and 18.24% for D104, D105, and D106. They displayed great potential with improved stability in inverted planar PSCs. The unencapsulated device in ambient environment (30% RH) based on D104, D105, and D106 retained 33%, 70%, and 75% of the initial PCE after 275 h.

“…For the most broadly used anode interlayer, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), surface modification and doping are also effective approaches to enhance OSC property. For instance, surface modifying PEDOT:PSS with TTF-Py or doping PEDOT:PSS with Ti 3 C 2 T x could increase the W F and strengthen the hole transfer and collection ability of devices. On the basis of the abovementioned summary, the mechanism for interlayer control is relatively clear, including adjusting the W F (lower W F for a cathode and higher W F for an anode), improving the charge extraction ability (electron for a cathode and a hole for an anode), and enhancing the blocking ability of a reverse charge carrier.…”

In this study, an effective and simple approach for optimizing the performance of both cathode and anode interlayers in OSCs is demonstrated using 4-heptyl-4′-cyanobiphenyl (7CB) to dope a classic cathode (ZnO and SnO2) or an anode interlayer [poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)]. Because of the enhanced light absorption, improved physical contact between a photoactive layer and an interlayer, and increased carrier recombination, all of the devices based on a 7CB-doped interlayer show increased short-circuit current density (J sc), fill factor (FF), and power conversion efficiency (PCE) compared to the corresponding undoped interlayer, regardless it is the anode interlayer or the cathode interlayer, which is a rare phenomenon in the interlayer modification field.
