“…In addition, mobile ion migration into the electron/hole transport layer or metal electrode can cause failure of the corresponding functional layer, which will consequently lead to irreversible PCE degradation. 56,57 Therefore, during the heat aging process, the decomposition of materials (including the perovskite and functional layer) should be responsible for the degradation of all devices' PCE, which is of distinct difference from the voltage and light aging tests.…”

“…The device performance enhancement is ascribed to the fast interfacial charge extraction and efficient trap passivation. Moreover, the strong water resistance of the C-FPPS interfacial layer distinctly enhances the ambient stability of PSC devices, exhibiting a T 80 time of over 300 h under high-humidity conditions, which surpasses the control devices with a T 80 of only 130 h. [87] In 2022, Nejand et al reported two functionalized fullerenes (abbr. IPB, IPH), which were applied as interlayers to construct inverted Sn-Pb mixed narrow-bandgap (NBG) PSCs.…”

Comprehensive SummaryEfficient charge transport and defect passivation are essential for high efficiency of organic–inorganic hybrid perovskite solar cells (PSCs). Functionalized fullerenes featuring high electron affinity and mobility as well as small reorganization energy have been extensively applied in PSCs toward facilitated electron transport and passivated trap states, leading to improvements of both device efficiency and stability. Herein, we summarize the recent advances, especially in the last three years, in applications of functionalized fullerenes including fullerene derivatives and endohedral metallofullerenes in PSCs. Their functions in trap state passivation, electron transport promotion, crystalline modulation, water/oxygen erosion inhibition, and so on, are discussed in details. In particular, we emphasize novel functions of fullerenes beyond trap state passivation, as well as the synergy of multifunction of fullerenes in improving PSC device performance and stability. Finally, we present an outlook on designing novel multifunctionalized fullerenes toward highly efficient and stable PSC devices.

“…Xie et al also employed a cross‐linkable fullerene IL, namely 1‐( p ‐benzoate‐( p ‐methylvinylbenzene)‐indolino[2,3][60]fullerene (FPPS), as shown in Figure 7c, to enhance humidity stability of the devices. [ 113 ] After thermal cross‐linking, they surprisingly found an increase in electron mobility of IL films, which dramatically promoted interfacial charge extraction. More importantly, the coverage with cross‐linked ILs bolstered both solvent‐ and moisture‐resistant ability of the devices, lending better protection to the bottom perovskite films against extrinsic intrusion, which is of both short‐ and long‐term nature.…”

Perovskite solar cell (PSC) is a potential next-generation photovoltaic technology alternative to the conventional competitors including polycrystalline silicon, cadmium telluride, and copper indium gallium diselenide solar cells. Particularly, functionalized fullerenes play crucial roles as charge transport layers, interfacial layers, and additives in perovskite photovoltaics, dramatically contributing to the promotion of power conversion efficiency (PCE) and stability. As the field advances rapidly, the importance to rationally design fullerenes against a particular category of those functions has been increasingly recognized. Herein, recent progress in the application of functionalized fullerenes toward highperformance and stable perovskite solar cells is reviewed, placing special emphasis on the importance of the targeted molecular design of fullerene structures for different application scenarios to meet diverse functional requirements in specific device structures.
