Abstract Organic–inorganic hybrid perovskite solar cells (PSCs) are regarded as a promising next‐generation photovoltaic technology. However, poor device stability limits their commercialization. Carbon‐based inorganic PSCs (C‐IPSCs) can meet challenge owing to the absence of organic components. Meanwhile, hydrophobic carbon materials hole transport layers and back electrodes simplify fabrication process, decrease costs, protect devices from moisture erosion. Since first attempt for C‐IPSCs in 2016, series strategies have been proposed improve performance, including technique optimization, solvent engineering, composition interface charge layer so on, power conversion efficiency rapidly increased initial 5% exceeding 15%. In this review, recent progress is summarized, existing challenges field discussed, followed by prospect future development.

Inorganic CsPbIBr2 perovskite solar cells (PSCs) have accomplished many milestones, yet their progress has been constrained by ion migration and phase separation. This study explores the modulation of crystallization kinetics halide through chlorobenzene (CB) antisolvent with bis(pentafluorophenyl)zinc (Zn(C6F5)2) additive. The photoluminescence absorption spectra reveal significantly reduced segregaton in film treated CB Zn(C6F5)2. Moreover, this research analyzes film's free carrier lifetime, diffusion length, mobility using time-resolved microwave conductivity transient spectroscopy after Zn(C6F5)2 modification. Consequently, modified PSCs offer a 12.57% power conversion efficiency (PCE), highest value among negligible hysteresis prolonged stability. Furthermore, under 1-m-deep water, display PCE 14.18%. These findings provide an understanding development phase-segregation-free films showcase prospective applications underwater systems.

Perovskite solar cells (PSCs) offer low costs and high power conversion efficiency. However, the lack of long-term stability, primarily stemming from interfacial defects susceptible metal electrodes, hinders their practical application. In past few years, two-dimensional (2D) materials (e.g., graphene its derivatives, transitional dichalcogenides, MXenes, black phosphorus) have been identified as a promising solution to solving these problems because dangling bond-free surfaces, layer-dependent electronic band structures, tunable functional groups, inherent compactness. Here, recent progress 2D material toward efficient stable PSCs is summarized, including role both interface electrodes. We discuss beneficial effects on perovskite growth, energy level alignment, defect passivation, well blocking external stimulus. particular, unique properties form van der Waals heterojunction at bottom are emphasized.

The charge recombination resulting from bulk defects and interfacial energy level mismatch hinders the improvement of power conversion efficiency (PCE) stability carbon-based inorganic perovskite solar cells (C-IPSCs). Herein, a series small molecules including ethylenediaminetetraacetic acid (EDTA) its derivatives (EDTA-Na EDTA-K) are studied to functionalize zinc oxide (ZnO) interlayers at SnO2 /CsPbI2 Br buried interface boost photovoltaic performance low-temperature C-IPSCs. This strategy can simultaneously passivate in ZnO films, adjust alignment, release tensile stress, thereby improving contact, inhibiting ion migration, alleviating recombination, promoting electron transport. As result, maximum PCE 13.94% with negligible hysteresis effect is obtained, which one best results reported for CsPbI2 C-IPSCs so far. Moreover, optimized devices without encapsulation demonstrate greatly improved operational stability.
