Dr. Jigang Wang

 

Dr. Jigang Wang is a prominent researcher in his field and has recently been a large contributor to the field of spectroscopy and microscopy. Dr. Wang began his higher education by getting his Bachelors in Physics at Jilin University in China in 2000. He then went on to earn a masters and subsequent Phd in Electrical and Computer engineering at Rice University in 2002 and 2005, respectively. He is currently a Professor of Physics and Astronomy at Iowa State University. In addition to his teaching role, he is also the senior scientist at the company Ames Lab where some of his more prominent research has come from.

One of these new findings has been a result of his investigation of microscopy techniques at this company. More specifically, he has been investigating ultrafast microscopy techniques to aid in the identification of new and more efficient materials for use in the photovoltaic component of solar panels. To achieve this, he has been working on microscopy technology to detect light at the terahertz frequency. This frequency is between Infrared light and microwaves and is useful in developing photovoltaic materials. The wavelength of this light is around a millimeter, so in order to detect it Dr. Wang and his colleagues have developed a microscope sensor that is only 20 nanometers in radius. With the use of this sensor, they have identified the compound Methylammonium lead (MAPbI3) as a potential candidate for a new photovoltaic material that could replace the traditional silicon used today. Dr. Wang is one of the most prominent researchers in his field and his contributions have made great strides to both the development of microscopy tools and the development of new photovoltaic solar technologies.
