“…In order to enhance the intramolecular conjugation hole transfer, donor-acceptor (D-A) type, D-D type, strong planarity, large π-conjugation molecular designs have been mainly used for dopant-free HTM. [12][13][14][15][16] Charge carrier mobility between the adjacent molecules significantly increases if the materials exhibit self-assembling properties that can be exploited to generate ordered structures. 17,18 However, well-organized nanostructures are difficult to obtain with classic solution processing methods due to the disorder packing.…”

“…[ 158 ] Solution‐processable conjugated polymers and small molecules have been intensively used due to their multiple favorable characteristics such as high mobility, effective surface, defect passivation, and low temperature processibility. [ 159–164,183 ] In fact, these HTMs have shown comparable or better overall performances than spiro‐OMeTAD based devices, which are tabulated in Table 2. On the other hand, various metal oxides (i.e., NiO x , CuO) are also being explored as an alternative for organic HTMs.…”

Perovskite solar cells (PSCs) exhibit the steepest growth in power conversion efficiency among the existing photovoltaic technologies. However, a wide range of factors restrict the commercial viability of PSCs as a renewable energy source. This article reviews the latest progress in PSC devices including innovative light‐harvesting perovskite materials and advanced interfacial layers, and the foremost challenges. The most promising remedial solutions to challenges are also discussed. For the realization of a high performing and eco‐friendly stabilized perovskite photovoltaic device, a combinational method involving multiple restorative solutions is required. A specific emphasis is given to unveiling interesting perovskite properties, and device fabrication approaches to the solutions. These remedies and strategies may help researchers to select appropriate methods and design their experiments to obtain a high photo‐conversion efficiency in photovoltaic devices with enhanced stability as compared to conventional photovoltaic devices.

“…Son and co-authors introduced fluorine atoms to the molecules for adjusting the planarity of the backbone and the molecular packing through sulfur–fluorine interactions, which significantly increased the hole mobility and the PCE from 8.95% (S4) to 14.45% (S5) (Yun et al, 2016 ). Very recently, through a comprehensive study on the deliberate molecular design and modifications of electron donors, correlations between the planarity of HTMs backbone and performance of PSC were reported by Liang's group (Li et al, 2020 ). In this work, the dithieno[3,2-b:2′,3′-d]pyrrole (DTP) both end substituted by the twisted triphenylamine as the donor (S6) or the capped-by-planar- N -phenyl-carbazole donor were synthesized (S7).…”

Current high-efficiency hybrid perovskite solar cells (PSCs) have been fabricated with doped hole transfer material (HTM), which has shown short-term stability. Doping applied in HTMs for PSCs can enhance the hole mobility and PSCs' power conversion efficiency, while the stability of PSCs will be significantly decreased due to inherent hygroscopic properties and chemical incompatibility. Development of dopant-free HTM with high hole mobility is a challenge and of utmost importance. In this review, a series of selected and typical π-conjugated dopant-free hole transport materials, mainly regarding small molecules, are reviewed, which could consequently help to further design high-performance dopant-free HTMs. In addition, an outline of the molecular design concept and also the perspective of ideal dopant-free HTMs were explored.
