Biography

Dr. He Yan (Henry) obtained his Ph.D. in Chemistry from Northwestern University with Professor Tobin Marks. After that, Dr. Yan spent most of his research career at Polyera Corporation, a leading company in the Organic Electronics industry. From 2006 to 2012, Dr. Yan has been leading Polyera’s research projects in organic semiconductor and solar cell materials. In 2009, Dr. Yan and his team published the first high-mobility n-type semiconducting polymer in Nature and the work was referred to as the "new transistor age" on the cover page of Nature. Dr. Yan also set up Polyera’s organic solar cell project in 2008. The team later produced some of the highest organic solar cell efficiencies in the world. With these achievements, Dr. Yan was invited to receive the IdTechEx Printed Electronics "Best Organic Material" award in Dresden, Germany in 2010. Dr. Yan’s team also received Flextech's Flexi Award for R&D in 2011.

Previous relevant research work
