I will deliver my group's research work in dye-sensitized solar cells (DSCs) and their applications into the power sources of the internet of things (IoT) and hydrogen generation. First, a molecular-design strategy for integrating strong and weak electronic coupling in a single sensitizer will be presented to realize vectorial electron transfer, which is characteristic of natural photosystems, in DSCs. Our strategy of electronic coupling for inducing vectorial electron transfer could be potentially generalizable and improve the photovoltaic performance of DSCs. Next, by using a low-intensity indoor light, we develop a dye-sensitized photo-rechargeable battery (DSPB), which successfully operated a wireless IoT sensor. We expect DSPB will be an advanced energy device in terms of energy reuse and contribute to a carbon-neutral society by improving the energy efficiency of buildings. Lastly, I will present the stable dye-sensitized photoelectrochemical cells for hydrogen generation. |
