Research overview…
Sunlight has attracted a great deal of interest as sustainable energy, exhibiting the potential to be an alternative to coal and fossil fuels for alleviating the world energy crisis. When focusing on industrial tasks, solar cells which are electronic devices having an ability to convert sunlight directly into electricity should accommodate both high performance and cost-effectiveness. Therefore, I have paid much attention to the use of simple solution processes to fabricate various types of solar cells, e.g. organic (polymer), hybrid organic-inorganic (perovskite), and dye-sensitized solar cells. Moreover, modification of morphology, charge transport, and optoelectronic properties of solar materials using, for example, electrospinning and inkjet printing techniques has been also focused.
