Based on my long-term experience and knowledge on dye-sensitized solar cells, I have developed a novel photovoltaic cells using organo lead halide compounds as light-absorbing materials---perovskite solar cells. Triggered by our pioneering works, perovskite solar cells have been of explosive research interests all over the world thanks to their potential as low-cost, large-area high-efficiency thin film solar cells. My first paper on perovskite solar cells published in 2009 has been cited more than 4400 times, and the cumulative citation of all my papers has reached over 17000 (as of October 2017). We are now focusing on practical use of perovskite solar cells and dye-sensitized solar cells, and studying on application of these technologies to flexible devices and photodetectors.
