“…Siva et al added S-SWCNTs to each interface of perovskite/TiO 2 ETL and perovskite/poly(3-hexylthiophene-2,5-diyl) (P3HT) HTL, respectively [29]. The device architecture of the fabricated solar cells was FTO/TiO 2 :S-SWCNT/CH 3 NH 3 PbI x Cl 3−x /S-SWCNT:P3HT/Au and the S-SWCNTs were purchased from NanoIntegris (tables 3A and 4A).…”

“…The device application of S-SWCNTs was first reported in 1998 as the p-type metal-oxide semiconductor field-effect transistor [17]. The device application later extended further to organic solar cells where S-SWCNTs functioned as a photoactive material [18][19][20], a charge-transporting material [21][22][23][24][25][26][27], and an interfacial material [28][29][30][31]. With the emergence of perovskite solar cells (PSCs), the S-SWCNT continued to play a role in a similar manner [16,[32][33][34].…”

“…Accordingly, there have been numerous reports on such applications where SWCNTs functioned as the electrode [35][36][37][38][39][40][41], photoactive material [18], the charge-transporting material [21-24, 27, 42-47], and an interfacial material [29] (figure 1). Some of the review papers nicely outline the role of SWCNTs in PSCs from the energetics perspective [32][33][34] as well as thermodynamic and kinetic perspectives [16].…”

Single-walled carbon nanotubes (SWCNTs) are representative one-dimensional materials that show exceptional optical and electronic properties with various tuneable bandgaps. SWCNTs can be integrated into a variety of photovoltaics particularly, perovskite solar cells (PSCs) based on a high level of functionality and purity. In this topical review, we discuss the fundamentals of SWCNTs applied to PSCs as an electron-transporting layer (ETL), hole-transporting layer (HTL), photoactive layer, and interfacial materials from the literature. Firstly, SWCNTs in PSCs and their defect control properties improving the devices are discussed. Subsequently, electrical and morphological improvement of semiconducting SWCNT (S-SWCNT)-added PSCs and other types of CNTs used in PSCs are discussed chronologically. The review and discussion layout the strategies of incorporating SWCNTs within the design frame of next-generation PSCs towards the improvement of the device performance via defect passivation.

Hybrid Titanium dioxide/Poly(3-hexylthiophene) heterojunction solar cells have gained research interest as they have the potential to become cost-effective solar technology in the future. Limited power conversion efficiencies of about 5–6% have been reported so far, and an enhancement in efficiency was achieved through the engineering of the interface between Titanium dioxide (TiO2) and Poly(3-hexylthiophene) (P3HT). Evolution of this solar cell technology is relatively slow-moving due to the complex features of the metal oxide-polymer system and the limited understanding of the technology. In this review, we focus on recent developments in interface modified hybrid Titanium dioxide/Poly(3-hexylthiophene) solar cells, provide a short discussion on the working principle, device structure with interface modifiers, and summarize various types of interface modifiers studied to enhance the photovoltaic performance of hybrid TiO2/P3HT heterojunction solar cells. Further, we discuss the key factors influencing the power conversion efficiency and the role of a variety of interface modifiers in this regard. Finally, the challenges and perspectives related to hybrid TiO2/P3HT heterojunction solar cells are also explored.

“…demonstrated the suppressed charge recombination of PSCs by inserting an interlayer of SWCNTs to the interface between TiO 2 and perovskite for mesoscopic n–i–p structured PSCs. [ 179 ] Such an interfacial modification promoted a PCE improvement from 9.3% to 13.6% owing to the increased J sc and V oc . This may be attributed to the passivation effect of the electronic defect state at the TiO 2 /perovskite interface in the presence of SWCNTs, resulting in energetically favorable electron transfer and decreased series resistance.…”

Metal halide perovskite solar cells (PSCs) have emerged as promising next‐generation photovoltaic devices with the maximum output efficiency exceeding 25%. Despite significant advances, there are many challenges to achieve high efficiency, stability, and low‐cost simultaneously. Combating these challenges depends on developing novel materials and modifying conventional device components. Carbon nanotubes (CNTs) have attracted considerable attention for fabricating efficient PSCs owing to their remarkable electrical, optical, and mechanical properties. With their multifunctional features, CNTs can play a wide range of roles and offer unique benefits in various components in PSCs to improve device performance and durability. Here, recent progress concerning the utilizations of CNTs as transparent conductive electrodes, charge‐transporter, perovskite additives, interlayers, hole‐transporting materials, and back electrodes in PSCs is comprehensively reviewed. The application of CNTs toward the development of 1D and 2D flexible PSCs is also discussed. A summary of current challenges and prospective on future research directions of employing CNTs to realize high‐performance PSCs is presented.
