Research Interests: Grid-level energy generation and storage solutions.
Maxwell Zheng is a Ph.D. student at the University of California, Berkeley performing research on photovoltaics, solar fuel generation, and grid-level energy storage. His primary focus is on low-cost, high-efficiency III-V solar cells. He recieved his B.S. from UC Berkeley in 2010, where he previously worked on graphene synthesis as an SRC undergraduate researcher.
Direct Growth of High Quality III-V Semiconductors on Metal Foils for Low-Cost, High-Efficiency PVs [BPN625]
The intrinsic advantages of III-V semiconductors for solar cells have been hobbled by the lack of low-cost substrates and processes, which has thus far limited market success of III-V solar cells. Here at Berkeley we are exploring a non-traditional approach which addresses these drawbacks. High optical quality polycrystalline InP films have been grown on non-epitaxial molybdenum substrates. Remarkably, these films with micron-sized grains have similar photoluminescence qualities as single- crystalline InP, and show great promise for high-efficiency, low-cost solar cells.
