One of the most widely used energy sources nowadays is nonrenewable, but the excessive consumption of these resources leads to environmental issues. Therefore, renewable energy sources have received much attention, including photovoltaic energy. A novel technology known as “third‐generation solar cells” is being studied, and in this class, the polymeric solar cells (PSCs) and the perovskite solar cells (PVSKs) can be highlighted. Several researchers are trying to find new ways to improve the energy conversion efficiency (PCE) and long‐term stability of these devices. In particular, PVSK has already demonstrated high PCE, but there is still a long way to go to develop more stable and better processable devices for large‐scale production. In the case of PSC, processability is a positive factor since its flexible films have great mechanical stability and can be processed in roll‐by‐roll systems. However, efficiency is still a challenge for researchers. Nevertheless, both types of devices are good alternatives for silicon cell substitution. However, further studies are needed to address the inherent problems of each device technology and move to large‐scale production.

“…The four main components used in the fabrication of DSSCs are the photoanode material (semiconductor), the dye molecule (a photosensitizer), the redox electrolyte, and the counter electrode. − In 1991, Grätzel and O’Regan published the first study on DSSCs using N3 dye as a photosensitizer . Numerous studies in this field since the original work on DSSCs have primarily shown that various dyes (photosensitizers) have been molecularly engineered and used in DSSCs. − The production of novel photosensitizers that can be developed in DSSCs is an essential component affecting device efficiency. − …”

This research focuses on the first demonstration of NO2Lw (2-hydroxy-3-nitronaphthalene-1,4-dione) as a photosensitizer and TiO2, ZnO, and Nb2O5 as photoanode materials for dye-sensitized solar cells (DSSCs). The metal-free organic photosensitizer (i.e., nitro-group-substituted naphthoquinone, NO2Lw) was synthesized for this purpose. As a photoanode material, metal oxides, such as TiO2, ZnO, and Nb2O5, were selected. The synthesized NO2Lw contains an electron-withdrawing group (−NO2) and anchoring groups (−OH) that exhibit absorption in the visible range. The UV–visible absorbance spectrum of NO2Lw demonstrates the absorption ascribed to ultraviolet and visible region charge transfer. The NO2Lw interacts with the TiO2, ZnO, and Nb2O5 photoanode, as shown by bathochromic shifts in wavelengths in the photosensitizer-loaded TiO2, ZnO, and Nb2O5 photoanodes. FT-IR analysis also studied the bonding interaction between NO2Lw and TiO2, ZnO, and Nb2O5 photoanode material. The TiO2, ZnO, and Nb2O5 photoanodes loaded with NO2Lw exhibit a shift in the wavenumber of the functional groups, indicating that these groups were involved in loading the NO2Lw photosensitizer. The amount of photosensitizer loading was calculated, showing that TiO2 has higher loading than ZnO and Nb2O5 photoanodes; this factor may constitute an increased J SC value of the TiO2 photoanode. The device performance is compared using photocurrent–voltage (J–V) curves; electrochemical impedance spectroscopy (EIS) measurement examines the device’s charge transport. The TiO2 photoanode showed higher performance than the ZnO and Nb2O5 photoanodes in terms of photoelectrochemical properties. When compared to ZnO and Nb2O5 photoanodes-based DSSCs, the TiO2 photoanode Bode plot shows a signature frequency peak corresponding to electron recombination rate toward the low-frequency region, showing that TiO2 has a greater electron lifetime than ZnO and Nb2O5 photoanodes based DSSCs.

“…reported the metal-ion coordination strategy to increase the V oc of DSSCs via slowing charge recombination kinetics but sacrificing the dye regeneration rate, which leads to inferior efficiency for optimized devices . In addition, adopting coadsorbents to suppress dye molecule self-aggregation on photoanodes and weaken the derived charge carrier recombination to increase the efficiency of DSSCs has been regarded as a universal strategy. , However, the photon-harvesting capability of DSSCs based on coadsorbents would be somewhat impaired for the reduced dye molecule loading on the photoanode . Even though great progress has been achieved for DSSCs, it is still challengeable for holistically optimizing the charge carrier events involved in DSSCs for further improving their efficiency.…”

Charge carrier events across organic electronics are ubiquitous, and the derived optimization plays a crucial effect on improving the performance of organic electronics. Herein, a two-dimensional material (Ti3C2T x ) is incorporated into titanium dioxide (TiO2) to impart the Ti3C2T x /TiO2 hybrid film enriched hydroxy group distribution, defect-negligible surface, upshifted work function, and enhanced conductivity yet electron mobility versus the pristine TiO2 film. Therefore, intensified photon-harvesting ability, reduced charge carrier recombination, and efficient charge carrier collection are realized for dye-sensitized solar cells (DSSCs) based on the Ti3C2T x /TiO2 hybrid photoanode relative to control ones. Consequently, the modified DSSCs based on Z907 deliver superior efficiencies of 10.39 and 29.68% under 100 mW/cm2 illumination and ∼1.9 mW/cm2 dim light, respectively, being the highest values of Z907-based DSSCs. However, control devices only obtain lower efficiencies of 8.06 and 23.91% when undergoing the abovementioned illumination. On the other hand, the self-powered homologous photodetectors with the hybrid film as an electron-transporting layer present enhanced detectivity (1.69 × 1011 Jones) and a shortened responsivity of 0.26 s versus that of control ones (1.39 × 1011 Jones and 0.35 s). Our work implies that the Ti3C2T x /TiO2 hybrid film features high potential for improving the performance of organic electronics for its effect of holistically optimizing charge carrier dynamics.
