Dye‐sensitized solar cells (DSSCs) are a feasible alternative to traditional silicon‐based solar cells because of their low cost, eco‐friendliness, flexibility, and acceptable device efficiency. In recent years, solid‐state DSSCs (ss‐DSSCs) have garnered much interest as they can overcome the leakage and evaporation issues of liquid electrolyte systems. However, the poor morphology of solid electrolytes and their interface with photoanodes can minimize the device performance. The photosensitizer/dye is a critical component of ss‐DSSCs and plays a vital role in the device‘s overall performance. In this review, we summarize recent developments and performance of photosensitizers, including mono‐ and co‐sensitization of ruthenium, porphyrin, and metal‐free organic dyes under 1 sun and ambient/artificial light conditions. We also discuss the various requirements that efficient photosensitizers should satisfy and provide an overview of their historical development over the years.

Polyoxometalates (POMs) can enable energy level tuning to match perovskite layers. They are considered electronic bridges to modify perovskite and improve the performance of photovoltaic devices. Therefore, in the present work, we dispersed the vacancy POMs K 8 [α-SiW 11 O 39 ]•H 2 O ({SiW 11 }) in the metal-organic frameworks (MOFs) to modify the perovskite layer. {SiW 11 } could adjust the energy level between the layers of the perovskite photodetector. Moreover, the hydrogen bonds formed between SiW 11 @ZIF-8 and perovskite effectively passivated the grain boundaries (GBs) of the perovskite layer. Xray diffraction spectroscopy (XRD) showed that the crystallinity of perovskite was significantly improved. In addition, scanning electron microscopy (SEM) images demonstrated that the average size of perovskite grains increased from 254.50 to 719.27 nm, proving the effective passivation of the GBs. Furthermore, a series of tests such as infrared spectroscopy (IR), N 2 adsorption/desorption isotherms, transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS) also proved that {SiW 11 } could be successfully loaded into the pores of ZIF-8 through electrostatic interactions. The photocurrent of the SiW 11 @ZIF-8 doped device reached 41.95 μA, about three times as high as that of the blank device (14.41 μA). Also, under unencapsulated conditions, it could still maintain more than 90% stability for nearly 700 h.

All solidification is the only way for dye‐sensitized solar cells (DSSCs) to achieve commercial application. At present, the intricate and expensive approaches such as vapor deposition used for DSSCs based on hole transport materials are unsuitable for the development of large‐scale all‐solid‐state devices. Herein, a new avenue for the evolution of all solid‐state DSSCs through dissolving the I−/I3− redox couple in commercial UV glue and then solidifying under UV light as electron transport materials is put forward. Not only does this device show superior stability (the power conversion efficiency (PCE) can be maintained more than 95% after 1000 h), but also an optimum PCE of 6.15% (short‐circuit photocurrent density = 11.93 mA cm−2, open‐circuit voltage = 683 mV, fill factor = 0.75) is obtained. It must be the best choice for the future development of all‐solid‐state DSSC device.
