摘要
The unique features of dye-sensitized solar cells (DSCs) with low-cost, easy-assembly, and nature-friendly benefits make them suitable for renewable energy. However, the adsorption of dye on porous TiO 2 surface, usually conducted by a long time immersion (16-24 h) to offer an optimized dye adsorption condition, is a time-consuming process, which inevitably limits their potential in production capacity and throughput. Accordingly, developing a simple route to reduce the dye adsorption process is urgently required. Herein, we present a facile, rapid, efficient sensitization route for efficiently controlling the adsorption of N719 dye on TiO 2 via microwave irradiation for the first time in this work. The dye adsorption condition on TiO 2 can be easily tuned with the number of microwave times and the microwave duration via the microwave-induced thermal effect. Our result reveals that the conversion efficiency of DSCs after the microwave treatment in a short time can be significantly increased, leading to 43% improvement in the conversion efficiency as compared with that without microwave treatment.
