Abstract / Description: 

Thin-film solar cells, which use light-weight, highly-absorbing semiconductors, have the potential to dramatically lower manufacturing costs and accelerate deployment of solar energy via mechanically flexible architectures. Hybrid metal halide perovskites are the leading materials for this next-generation solar technology by virtue of their unprecedented optoelectronic properties and their synthesis from earth-abundant elements. The groundbreaking promise of perovskites is that they can be manufactured by scalable solution-coating methods, making them a potentially low-cost and high-performance energy technology with projected levelized cost of electricity (LCOE) below 3¢ / kWh.

This talk will discuss the current understanding of the optoelectronic properties of perovskites as well as how these properties inform the design of single-junction and tandem perovskite-silicon cell architectures. We will consider routes to upscaling perovskite module fabrication and look at challenges related to the fundamental thermomechanical reliability of these material systems.


Will Scheideler is a postdoctoral scholar in the Dauskardt research group in the Department of Materials Science and Engineering at Stanford, where he studies scalable fabrication and thermomechanical reliability of perovskite solar cells. Will graduated from Duke University in 2013 with a B.S. in Electrical Engineering and a B.S. in Biomedical Engineering. He completed his Ph.D. as an NSF Graduate Research Fellow in Electrical Engineering at the University of California, Berkeley, in 2017. His doctoral thesis, advised by Prof. Vivek Subramanian, explored scalable manufacturing of transparent metal oxide transistors. Will is joining the faculty of Dartmouth's Thayer School of Engineering in Summer 2019, where he will lead a research group exploring nanomanufacturing of high-performance flexible and printed devices, including low-power sensing and solar energy harvesting for hybrid electronics.
