Modelling and Design of Nanostructured Optoelectronic Devices : Solar Cells and Photodetectors

This book approaches the design of functionally superior optoelectronic devices through the use of bio-inspired nanostructures and multiscale material structures through a step-by-step approach. The book combines both the fundamental theoretical concepts involved in understanding and numerically modelling optoelectronic devices and the application of such methods in addressing challenging research problems in nanostructured optoelectronic design and fabrication. The book offers comprehensive content in optoelectronic materials and engineering and can be used as a reference material by researchers in nanostructured optoelectronic design.

Jagdish A. Krishnaswamy is a post-doctoral researcher at the iMEMS research group at the Indian Institute of Science (IISc), Bangalore, India. Previously, he was a post-doctoral fellow at the MS2Discovery interdisciplinary institute at Wilfrid Laurier University, Canada.
