“…Therefore, in this study, we conducted biomimetic doping optimization on the block-like transparent anatase TiO 2 (TA TiO 2 ) thin film from the previous work. − The mountain hydrangea, originally a white flower, turns transparent when exposed to water, revealing the veins inside the petals and earning it the nickname “skeleton flower”. − This plant is found in Eastern Asia and the eastern part of North America. , By studying the tissue structure of the mountain hydrangea’s petals, we found that water permeates the uneven surface of the petals, changing their transparency and creating a unique transparent beauty after rain . At the same time, the presence of the veins strengthens the structural integrity of the petals and transfers nutrients.…”

In this research, the structural characteristics of the mountain holly leaf were emulated. It was observed that after the initially uneven surface of the petals is filled with infiltrated water, it exhibits a distinctive transparent beauty after rainfall. Furthermore, the presence of leaf veins enhances the structural strength of the petals and facilitates nutrient transport. Inspired by previous studies on double-layer spin-coated films, we further developed and designed the TA TiO 2 @MWCNT photocathode thin film. This innovative film incorporates multiwalled carbon nanotubes (MWCNT) into a previously established TA TiO 2 photocathode thin film. The inclusion of MWCNT results in the formation of a three-dimensional highway structure, where MWCNT intertwines within the TA TiO 2 film. Under the operational state of immersion in the electrolyte, it maintains a level of transparency similar to that of the TA TiO 2 photoanode thin film. The high-temperature sintering process results in the oxidation and depletion of MWCNTs on the surface of the film, leaving behind uniformly dispersed concave defects, thereby greatly enhancing the specific surface area. The findings demonstrate that the optoelectrode of high transparency and high specific surface area, TA TiO 2 @MWCNT, comprehensively enhances the performance of the solar cells. The transparent QDSSC surpasses its counterparts for the first time, achieving a power conversion efficiency (PCE) of 6.335%. This sets the stage for new materials and innovative approaches in the field of solar cells and other titanium dioxide film-related areas.

“…Compared with the anatase TiO 2 nanoparticle (NP) film, the transparent anatase TiO 2 film has extremely high visible light transmittance, and lower resistance and carrier recombination rate . The transfer of photogenerated charge carriers no longer needs to cross the interface barrier between TiO 2 NPs, which reduces the recombination rate of photogenerated charge carriers and shortens the transport distance of photogenerated charge carriers. , The internal resistance of the assembled QDSSC is more suitable. The fill factor (FF) is increased from 37.6 to 54.7%.…”

In this work, we propose a strategy that is different from the traditional technology of increasing the specific area of the TiO 2 film to improve the carrying capacity of QDs in QDSSCs. Transparent anatase TiO 2 films are prepared by improving the optical transmittance of the photoanode TiO 2 film so that the attached QDs can capture more photons and improve the efficiency of utilizing QDs. This QDSSC preparation technology sacrifices part of QDs loading but improves the utilization efficiency of QDs. At the same time, the transparent bulk TiO 2 film decreases the transmission distance of photogenerated charge carriers, reduces the cross-interface transport, optimizes the transmission path, and reduces the carrier capture composite rate compared with the TiO 2 particle film. Therefore, it not only increases the V oc , FF, and PCE of QDSSCs to 0.628 V, 54.7, and 6.166%, respectively, but also has greater transparency. It meets the demand for solar cell transparency in practical applications and has a wider range of applications and better aesthetics. The mechanism simulation and theoretical analysis of photothermal conversion and electromagnetic mechanism show that the barrier of carrier transfer in bulk transparent anatase TiO 2 is lower than the physical barrier between anatase TiO 2 NPs. The advantages of the anatase transparent TiO 2 film in the process of photogenerated charge carrier transmission are verified. It provides an idea for the development of QDSSCs. It also brings the technology of transparent TiO 2 film to related fields.
