A Pioneer in 2D Materials Research for Photovoltaic Applications
Sayan Roy is a distinguished researcher specializing in nanoelectronics, semiconductor devices, and quantum materials, with significant contributions to the field of photovoltaic applications. After completing his education at Purdue University, he has established himself as an expert in modeling ultrathin 2D Transition Metal Di-Chalcogenides (TMDCs). His groundbreaking research includes developing novel approaches for tungsten-based TMDCs in solar energy applications, particularly focusing on space photovoltaics. His most influential work, published in Solar Energy Materials and Solar Cells, explored the electronic and optical properties of ultra-thin 2D tungsten disulfide. Roy's research has garnered significant attention, with his publications receiving numerous citations, particularly for his work on enhancing photovoltaic current through dark states in donor-acceptor pairs of tungsten-based TMDCs. His doctoral research at Purdue University under Prof. Bermel's supervision has led to innovative developments in radiation-resistant photovoltaic materials for space applications. Currently working at the Defense Advanced Research Projects Agency (DARPA), Roy continues to advance the field of nanoelectronics and semiconductor devices, with particular emphasis on quantum materials and their applications in next-generation solar technology.
