Muhammad Ashraful Alam is the Jai N. Gupta Professor of Electrical Engineering at Purdue University where his research and teaching focus on physics, fundamental limits, and technology of classical and emerging semiconductor devices. From 1995 to 2003, he was with Bell Laboratories, Murray Hill, NJ, where he made fundamental contributions to the reliability physics of semiconductor devices and design of optoelectronic integrated circuits. Since joining Purdue in 2004, Dr. Alam has published over 200 papers on a broad range of topics involving biosensors, flexible electronics, reliability and solar cells. He is a fellow of IEEE, APS, and AAAS and the recipient of 2006 IEEE Kiyo Tomiyasu Award for contributions to device technology for communication systems, and 2015 SRC Technical Excellence Award for contribution to semiconductor reliability physics. Prof. Alam enjoys teaching: more than 100 thousands students worldwide have learned some aspect of semiconductor devices from his web-enabled courses.

Ultimate and Global Performance Limits of Bifacial Tandem Solar Cells: Can HIT-Perovskite PV Reach this Fundamental Limit?
A solar cell is horribly inefficient. Had the sunlight not been free, no one would care about an “engine” that wastes two-thirds of the input energy at the cell level and five-sixths of the incident energy at the farm level.
