“…As summarized in Table 2, most of the PSCs in the literatures had a higher PCE than our device. 6,[44][45][46][47][48][49][50][51] Notably, these PSCs based on the flexible transparent electrodes possessed good bending stability, but most of the flexible electrodes are difficult to stretch. Due to the good flexibility of the transparent NF electrode, the flexible PSCs can be integrated with some outdoor textiles, such as jackets, backpacks, and tents, as presented in Figure 9.…”

The flexible transparent electrode is a crucial component of wearable photoelectric devices, and has a significant influence on the performance and development of wearable devices. Here, a phosphor/polyimide/polyurethane@silver composite nanofiber (NF) web electrode was fabricated by electrospinning and magnetron sputtering for wearable photoelectric devices. The electrode demonstrated a promising light management ability with converting ultraviolet light to visible light, high conductivity with sheet resistance of 22.1 Ω/square, and high transparency with transmittance of over 80%. Besides, the electrode possessed an excellent stretched capacity with tensile strain of over 100%, and tensile stability with the resistance increased by ∼75% after 500 stretching cycles at the tensile stain of 50%. As a result, a flexible perovskite solar cell (PSC) was assembled by using the NF web electrode, and possessed the power conversion efficiency of 3.47%, which is higher than that of PSCs based on electrodes without phosphor. Furthermore, the flexible PSCs exhibited promising mechanical stability under bending, and could serve as wearable devices. This work provides a feasible and promising method to prepare lightweight, stretchable, light management, and transparent electrodes for photoelectric devices, and may facilitate the development of wearable photoelectric devices.

A low‐cost and indium‐tin‐oxide (ITO)‐free electrode‐based flexible perovskite solar cell (PSC) that can be fabricated by roll‐to‐roll processing shall be developed for successful commercialization. High processing temperatures present a challenge for the PSC fabrication on flexible substrates. The most efficient planar n–i–p PSC structures, which utilize a metal oxide as an electron transport layer (ETL), necessitate high annealing temperatures. In addition, the device performance deteriorates owing to the migration of halogen ions, which causes the oxidation of the metal electrodes. These drawbacks conflict with the development of highly efficient flexible PSCs fabricated on ITO‐free transparent electrodes. Herein, an efficient ETL material that enables low‐temperature processing is presented. Tin dioxide (SnO2) is modified by (sulfobetaine‐N,N‐dimethylamino)propyl naphthalene diimide (NDI‐B) and used as an ETL. The NDI‐B effectively reduces the interfacial nonradiative recombination between the ETL and perovskite and suppresses the ion migration by passivating oxygen‐vacancy defects in SnO2 and strongly interacting with halogen ions, respectively. Based on the NDI‐B‐blended SnO2 ETL, a record PCE of 17.48% is achieved in the ITO‐free flexible PSC fabricated at low temperature.
