Research Bio

Peidong Yang is a chemist and materials scientist whose research lies at the intersection of nanoscience, energy conversion, and synthetic biology. He is internationally recognized for pioneering work in semiconductor nanowires and the design of hybrid materials that mimic natural photosynthesis.

Yang's contributions to nanoscience and technology include the invention of the first nanowire nanolaser in 2001, the prototype development of gate-all-around (GAA) nanowire transistor architecture in 2005, and the introduction of the first photosynthetic biophotonic leaf in 2015.

Yang is best known for creating artificial photosynthetic systems that integrate semiconductors and biological components to convert sunlight, water, and carbon dioxide into fuels. His work has opened new frontiers in sustainable energy and has laid the groundwork for carbon-neutral chemical manufacturing.

An expert in nanomaterials and energy science, Yang is a professor in the Department of Chemistry at the University of California, Berkeley, and holds joint appointments in the Materials Science & Engineering Department and the Kavli Energy NanoSciences Institute. He is a member of the National Academy of Sciences and the American Academy of Arts and Sciences, and a recipient of the MacArthur Fellowship.

Scientists Grow Lead-Free Solar Material With a Built-In Switch

Solar panels, also known as photovoltaics, rely on semiconductor devices, or solar cells, to convert energy from the sun into electricity. Manufacturers typically dope the solar cell with chemicals so that one layer of the device bears a positive charge and another layer a negative charge. But chemical doping and layered synthesis also add extra costly steps in solar cell manufacturing.

First Blue LED Emission from a Perovskite

IEEE Spectrum

Jeff Hecht

An unprecedented blue light-emitting diode, or LED, using the inexpensive and natural mineral perovskite has been created by a team of Berkeley researchers led by chemistry professor Peidong Yang. Until now, perovskite LEDs have only put out red or green light, so the innovation offers new promise for electronic displays, but it also suggests potential instabilities in other applications, such as solar cells and transistors. For more on this, see our press release at Berkeley News.
