Dr. Chan’s research focuses on renewable energy sources. Tackling global warming is one of the major challenges facing our world in the 21st century. In order to reduce the production of greenhouse gases, we must develop efficient and economic renewable energy sources. Sunlight is the most viable source to power our planet due to its abundance. The major goal of his lab is to understand the physical mechanisms behind the next generation of photovoltaics and photocatalyst and to devise design principles for increasing the efficiency.
