“…However, the fact remains that both the perovskite absorbers and many organic HSLs (and their dopants) exhibit moisture sensitivity, and struggle to meet commercial stability targets. [ 71–75 ] Conventional metallic electrodes lack hydrophobic properties—a feature known to protect against these degradation mechanisms.…”

Carbon electrodes have gained significant attention as a cost‐effective, sustainable, stable, and scalable replacement for metal electrodes in perovskite solar cells (PSCs). However, traditional carbon‐electrode‐based PSCs (C‐PSCs) lack a hole‐selective layer (HSL) due to their incompatibility with the most effective organic HSLs employed in the PSC literature. In turn, the absence of an HSL has been identified as one of the main factors hindering the performance of C‐PSCs. Consequently, numerous studies have recognized the pivotal significance of the region between the perovskite absorber and the carbon electrode in C‐PSCs, proposing various interfacial engineering strategies to improve the performance of these solar cells. Given the rapid evolution of this field, an up‐to‐date and comprehensive review of C‐PSCs is in order. Key areas of focus of this review include the shift from high‐temperature to low‐temperature carbon electrodes, strategies to improve energetic alignment at the interface, novel approaches such as hole‐selective bilayers, and alternative carbon deposition methods to reduce solvent damage. Additionally, this review presents a comprehensive meta‐analysis—the first of its kind in the C‐PSC literature—to assess how various interfacial modifications impact critical C‐PSC performance metrics, offering valuable insights for future advancements in the field.This article is protected by copyright.

In the era of global energy crisis, more attention is paid to efficient energy harvesting from renewable sources. Solar power is one of those widely utilized, yet the efficiency of devices converting energy needs to be constantly improved. One of the ideas is to create solar cells that benefit from 2D van der Waals structures combined with other materials such as TiO2 and conductive polymers. Such hybrid solar cells show higher power conversion compared to non‐composite photovoltaic devices. In this work, a TiO2/MoS2 heterojunction created in the magnetron sputtering process was covered with a P3HT polymer coating. Composite multilayer systems were investigated (TEM, XRD, Raman spectroscopy and TOF‐SIMS) to define the composition, optical properties and solar energy conversion potential. The photovoltaic response of the multilayer system was successfully improved by MoS2 band gap engineering based on the quantum size effect. Furthermore, TiO2/MoS2/P3HT revealed enhanced optical properties and improved charge transport performance with reasonable energy band alignment. The photovoltaic efficiency of hybrid cells doubled compared to previously published work and reached 2.7%. Furthermore, the photovoltaic performance of the solar cells based on TiO2/MoS2/P3HT exhibited an improvement compared to that of the solar cell based on TiO2/P3HT or MoS2/P3HT.

To push the commercialization of the promising photovoltaic technique of perovskite solar cells (PSCs), the three‐element golden law of efficiency, stability, and cost should be followed. As the key component of PSCs, hole‐transporting materials (HTMs) involving widely‐used organic semiconductors such as 2,2′,7,7′‐tetrakis‐(N,N‐di‐4‐methoxyphenylamino)‐9,9′‐spirobifluorene (Spiro‐OMeTAD) or poly(triarylamine) (PTAA) usually suffer high‐cost preparation and low operational stability. Fortunately, the studies on the classical p‐type polymer poly(3‐hexylthiophene) (P3HT) as an alternative HTM have recently sparked a broad interest due to its low‐cost synthesis, excellent batch‐to‐batch purity, superior hole conductivity as well as controllable and stable film morphology. Despite this, the device efficiency still lags behind P3HT‐based PSCs mainly owing to the mismatched energy level and poor interfacial contact between P3HT and the perovskite layer. Hence, in this review, the study timely summarizes the developed strategies for overcoming the corresponding issues such as interface engineering, morphology regulation, and formation of composite HTMs from which some critical clues can be extracted to provide guidance for further boosting the efficiency and stability of P3HT‐based devices. Finally, in the outlook, the future research directions either from the viewpoint of material design or device engineering are outlined.
