[ 118 ] To overcome the severe degradation problem of Spiro‐OMeTAD, Lei et al fabricated a Spiro‐OMeTAD/CuS double‐layer HTM (Figure 8d). The high intrinsic mobility of CuS could enhance hole transport and reduce charge recombination, yielding a high PCE of 18.58%.…”

Recent Progress in Perovskite Solar Cells Modified by Sulfur Compounds

In the past decade, organic–inorganic hybrid perovskite solar cells (PSCs) have begun to be increasingly studied worldwide owing to the superior properties of perovskite material. However, some issues have delayed their commercialization, such as their long‐term stability, cost reduction, scale‐up ability, and efficiency. The introduction of sulfur to PSCs can relieve the above issues because sulfur can passivate interfacial trap states, suppress charge recombination, and inhibit ion migration, thereby enhancing the stability of PSCs. Furthermore, PbS bonds provide new channels for carrier extraction. Herein, the sulfur‐based compounds utilized in PSCs are summarized and classified according to their functions in the different layers of PSCs. The results indicate that these sulfur‐based compounds have efficiently promoted the commercialization of PSCs. It is hoped that this review can help others understand the intrinsic phenomena of sulfur‐based PSCs and motivate additional investigations.

“…Tirado et al 116 have proceeded to the synthesis and characterization of p-type Cu sulfide nanoparticles that have been applied as a low-cost, fully inorganic HTM in mesoscopic n-i-p PSCs. By employing CuS combined with two different perovskites, CH 3 NH 3 PbI 3 (MAPbI 3 ) and (FAPbI 3 ) 0.78 (MAPbBr 3 ) 0.14 (CsPbI 3 ) 0.08 (CsFAMAPbIBr), very high current densities and fill-factors were observed, suggesting an effective hole-extraction at the CuS interface, which has led to a PCE close to 14%.…”

“…Tirado et al used CuS in normal device architecture (n-i-p) as a top HTL. [14] Han et al and Lei et al used Cu 1.8 S and Cu 1.75 S, respectively, in conjunction with Spiro-OMeTAD (2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenyl-amine)9,9′spirobifluorene) to improve the charge transfer through the HTL in normal device architecture PSC. [15] Rao et al used a very little amount of CuS nanoparticles for modifying the valence band maximum (VBM) position of indium tin oxide.…”

Inorganic hole-transport layers (HTLs) are widely investigated in perovskite solar cells (PSCs) due to their superior stability compared to the organic HTLs. However, in p-i-n architecture when these inorganic HTLs are deposited before the perovskite, it forms a suboptimal interface quality for the crystallization of perovskite, which reduces device stability, causes recombination, and limits the power conversion efficiency of the device. The incorporation of an appropriate functional group such as sulfurterminated surface on the HTL can enhance the interface quality due to its interaction with perovskite during the crystallization process. In this work, a bifunctional Al-doped CuS film is wet-deposited as HTL in p-i-n architecture PSC, which besides acting as an HTL also improves the crystallization of perovskite at the interface. Urbach energy and light intensity versus open-circuit voltage characterization suggest the formation of a better-quality interface in the sulfide HTL-perovskite heterojunction. The degradation behavior of the sulfide-HTL-based perovskite devices is studied, where it can be observed that after 2 weeks of storage in a controlled environment, the devices retain close to 95% of their initial efficiency.
