“…With considerable attention, CuPc and their derivatives have recently been utilized as a hole‐transporting layer (HTL) in PSCs with long‐term durability . Although soluble copper phthalocyanine has already been studied and published previously, the poor solubility of CuPc restricts its application in solution‐processable PSCs . Copper phthalocyanine‐3,4′,4′′,4′′′‐tetra‐sulfonated acid tetra sodium salt (TS‐CuPc) possesses good solubility in polar solvents, which brings to the potential application in low‐cost PSCs as an HTL.…”

Great efforts toward developing novel and efficient hole‐transporting materials are needed to further improve the device efficiency and enhance the cell stability of perovskite solar cells (PSCs). The poor film conductivity and the low carrier mobility of organic small‐molecule‐based hole‐transporting materials restrict their application in PSCs. This study develops an efficient and stable hole‐transporting material, tetrafluorotetracyanoquinodimethane (F4‐TCNQ)‐doped copper phthalocyanine‐3,4′,4′′,4′′′‐tetra‐sulfonated acid tetra sodium salt (TS‐CuPc) via a solution process, in planar structure PSCs. The p‐type‐doped TS‐CuPc film demonstrates improved film conductivity and hole mobility owing to the strong electron affinity of F4‐TCNQ. By the F4‐TCNQ tailoring, the composite film gives the highest occupied molecular orbital level as high as 5.3 eV, which is beneficial for hole extraction. In addition, the aqueous solution processed TS‐CuPc:F4‐TCNQ precursor is almost neutral with good stability for avoiding the electrode erosion. As a result, the fabricated PSCs employing TS‐CuPc:F4‐TCNQ as the hole‐transporting material exhibit a power conversion efficiency of 16.14% in a p–i–n structure and 20.16% in an n–i–p structure, respectively. The developed organic small molecule of TS‐CuPc provides the diversification of hole‐transporting materials in planar PSCs.

“…Subsequently, they increased the PCE to 13.65% by using a mixture of 16 and Al 2 O 3 as the buffer layer. 55 Gao et al synthesized a symmetric zinc Pc 17 bearing four thiophene groups with low bandgap characteristics as a HTM in perovskite solar cells. 56 They observed the time-resolved PL decay at the perovskite/compound 17 interface and revealed that 17 exhibited the quick quenching as same as spiro-OMeTAD.…”

“…After that, this group reported the replacement ofthe n‐butyl chain with triphenylamine and Cu(II) metal with Zn(II) in phthalocyanine. With the triphenylamine, improved electron cloud at core moiety, the solubility and uniform film formation all act favorably for this compound to be a potential HTM in PSCs . Triphenylamine‐substituted Zn phthalocyanine‐based solar cells exhibited 5.6 % efficiency without additives and with additives 9.0 % was achieved.…”

Spiro-OMeTAD is widely used as thehole-transporting material (HTM) in perovskite solar cells (PSC), which extracts positive charges and protects the perovskite materials from metal electrode, setting a new world-record efficiency of more than 20 %. Spiro-OMeTAD layer engross moisture leading to the degradation of perovskite, and therefore, has poor air stability. It is also expensive therefore limiting scale-up, so macrocyclic metal complex derivatives (MMDs) could be a suitable replacement. Our review covers low-cost, high yield hydrophobic materials with minimal steps required for synthesis of efficient HTMs for planar/mesostructured PSCs. The MMDs based devices demonstrated PCEs around 19 % and showed stability for a longer duration, indicating that MMDs are a promising alternative to spiro-OMeTAD and also easy to scale-up via solution approach. Additionally, this review describes how optical and electrical properties of MMDs change with chemical structure, allowing for the design of novel holemobility materials to achieve negligible hysteresis and act as effective functional barriers against moisture which results in a significant increase in the stability of the device. We provide an overview of the apt green-synthesis, characterization, stability and implementation of the various classes of macrocyclic metal complex derivatives as HTM for photovoltaic applications.
