“…According to diagrams of the variations of normalized PCE ( Figure a–c), FF (Figure 5d–f), J sc (Figure 5g–i), and V oc (Figure 5j–l) over time, when there is no interfacial layer between PSK and CuInS 2 layers, changes in the photovoltaic properties of prepared cells are more distinguishable. It seems that the interface of PSK and CuInS 2 will be improved over time (this is consistent with our previous results [ 42 ] ) but when we modify the interface with PMMA or PVK layer, the initial improvement is more effective and there are no significant changes in photovoltaic properties with time.…”

Different polymers have been already introduced for passivating the interfacial defects at the interface of perovskite and the organic hole transport material, meanwhile as an environmental barrier in perovskite solar cells (PSCs). Herein, polyvinylcarbazole (PVK) compared to polymethylmethacrylate (PMMA) at the interface of the perovskite (Cs0.05(MA0.83FA0.17)0.95Pb(Br0.17I0.83)3) layer and CuInS2/carbon as a low‐cost inorganic hole‐collecting electrode are investigated. By suppressing interfacial recombination using PMMA and PVK, saturation current density (in dark current) decreases one order of magnitude from 7.9 × 10−10 to 4.0 × 10−11 mA cm−2 by adding PMMA and two orders of magnitude to 9.4 × 10−12 mA cm−2 by adding PVK. By decreasing charge‐transfer resistance (measured by impedance spectroscopy), fill factor is increased (from 0.61) to 0.62 and 0.69, respectively. The efficiency of PSC with PVK/CuInS2/carbon hole‐collecting electrode is 17.69% that is significantly higher and more reproducible than that of PMMA/CuInS2/carbon and CuInS2/carbon hole‐collecting electrodes. It seems these interfacial layers also act as a barrier against penetration of carbon black and CuInS2 nanoparticles through the perovskite holes and have the functionality of a binder layer to improve the interfacial area.

“…Moreover, photoinduced oxidation and deformation of spiro-OMeTAD under illumination and heating are other destructive factors. − Sanchez and Mas-Marza concluded that the spiro-OMeTAD degradation under the working conditions is the main reason for the low stability of the PSCs . As a result, researchers have focused their attention toward developing scalable easy-to-manufacture methods for more stable, environmentally friendly, inexpensive HTMs to advance the design of PSCs toward commercialization. ,− …”

“…Currently, the semiconductors that are used as HTMs can be classified into organic polymers such as spiro-OMeTAD and inorganic materials such as metal chalcogenides and metal oxides. , According to the literature, p-type Cu-based chalcogenide semiconductors are promising substitutes due to their high hole mobility and low-cost synthesis processes. ,,− Copper(I) thiocyanate (CuSCN) provides adequate properties such as high hole mobility, proper energy-level matching, and simple preparation process. A high efficiency of 20.8% was achieved using the CuSCN/rGO bilayer film, which is deposited by the spin-coating technique in the mesoscopic n-i-p structure of FTO/TiO 2 /PVK/CuSCN/rGO/Au .…”

“…An efficiency of 15.6% was achieved for x = 0.5, Cu(In 0.5 Ga 0.5 )S 2 , which exhibited a suitable HOMO energy level, leading to a better charge extraction and a lower electron–hole recombination rate . For this semiconductor family and utilizing the low-cost carbon back electrode, Forouzandeh et al showed the best efficiency of 16.45% for CuIn 0.75 Ga 0.25 S 2 HTMs .

We investigate the use of simple nontoxic Cu 2 SnS 3 (CTS) nanoparticles (NPs) as low-cost dopant-free hole-transport materials (HTMs) a substitute for spiro-OMeTAD in an n-ip mesoscopic architecture of perovskite solar cells (PSCs). Besides, this work confirms the critical role of the crystalline phase of CTS NPs on the performance of the device. Using a facile one-pot heating-up procedure, pure zincblende and wurtzite structures of CTS NPs were obtained by sulfur element and thiourea as the sulfur source, respectively, and were dispersed in chloroform to make very stable nonpolar ink that is compatible with the perovskite. Nanoparticles with the wurtzite crystal phase showed much better photovoltaic performance compared to the zincblende phase with efficiencies of 13.01 and 7.87%, respectively. The efficiency of the reference solar cell using spiro-OMeTAD was 16.01%. Results from impedance spectroscopy and external quantum efficiency show that by switching from wurtzite-CTS to zincblende-CTS, the resistance of charge transfer at the perovskite/HTM interface is increased, which matches with the descending trend of fill factor of the corresponding cells. According to the morphological characteristics and electrical properties of HTM layers, the better performance of wurtzite-CTS in comparison with zincblende-CTS is due to two factors: (i) enhancement of the band-gap energy and alignment of the valance band maximum; and (ii) uniform smooth coverage of the perovskite film by monodispersed wurtzite-CTS NPs.

Despite the impressive progresses, perovskite solar cells (PSCs) employing operationally instable organic hole transporting layers (HTLs) are still far from the upscaling applications. Therefore, the development of new sustainable materials to meet the commercialization requirements is of great urgency. In addition, the high cost resulting from the complex production conditions of organic HTL materials is another limiting factor that must be overcome in the way of commercialization. Although various structures and types of HTL materials have been reported in this context, inorganic‐based materials have attracted the greatest attention both in terms of low‐cost and long‐term stability. However, inorganic HTL‐based cells have not yet reached the efficiency values of organic HTL‐based cells. In this mini Review, it is aimed to evaluate the alternative HTL materials only performing a destructive role in n‐i‐p architecture in terms of cell performance, stability, and cost. Hereof, a general evaluation of the HTL materials reported in the literature has been made and the effects of these materials on the cell performance have been elaborated and discussed.
