| 英文摘要 | The energy conversion process caused by relative motion of droplets and nanofilms has aroused widespread attention. However, the mechanism is still unclear, especially regarding the modification of the nanomaterial itself. In this study, we found that by annealing TiO2 in a H-2 atmosphere at different temperatures, the Magneli phase titanium suboxide can be prepared with a lot of oxygen vacancies. Oxygen vacancies not only form negative charge centers inside the film, which enhance the attraction of Na+, but also increase the carrier concentration. By increasing the oxygen vacancy concentration, the measured V-OC value was increased by similar to 5 times and ISC by similar to 30 times. Furthermore, a universal film preparation process was developed for the large-scale production of flexible energy conversion units based on the simple sol-gel method. Experimental results show that the prepared energy conversion unit has excellent performance of collecting rainwater energy and show a stable and continuous V-OC output of similar to 600 mV, combined with the surface hydrophobic treatment technology. |
