• VOC of about 700 mV, but virtually no JSC, producing PCE <0.1%. All solar cells henceforth were based on annealed Sb2S3 thin films. P3HT, as the hole transport material (HTM), was applied by immersing samples into a room-temperature solution of regioregular P3HT (2% w/w) dissolved in chlorobenzene

• (structured) window layer, Sb2S3 absorber layer, and hole transport material layer, and their respective interfaces, is a tremendous undertaking [4]. Attention has surged toward planar heterojunction Sb2S3 solar cells due to their simpler structure, less intricate production, and enhanced repeatability vs

• corresponding CB level (Figure 3b). This fact hints at the importance of the selection of an appropriate hole transport material for each particular HP composition to realize the potential of such materials to a full extent. The introduction of 10% Sn into CsPbIBr2 HP results in a bandgap narrowing from 1.90 to

• conditions, the role of the polymeric hole transport material is discussed. The efficiency of our best solar cells exceeds previous reports for each processing route, and our champion device displays one of the highest efficiencies reported for planar antimony sulfide solar cells.

• ; hole transport material; solar cell; Introduction Antimony sulfide (Sb2S3) is a promising high band gap light absorber for solar cells [1][2][3][4][5]. The record efficiency of 7.5% [6] is comparable to that of other less investigated materials, such as the best lead-free perovskites [7], Cu2O [8] and

• thin absorber (ETA) architecture, which is similar to that of dye-sensitized solar cells [21]. A thin absorber layer of around 10 nm [22] is deposited on a mesoporous TiO2 scaffold and the pores are subsequently filled with a hole transport material (HTM). Progress in terms of device efficiency can be
