Photocurrent Altered with Nanoparticles

Michael A. Greenwood

Sprinkling nanoparticles over the active face of photodetectors and solar cells could be a relatively easy and inexpensive way to enhance the performance of these devices. But exactly what effect do these tiny particles have, and what size, material and geometry are needed to accomplish these improvements? Researcher Naomi J. Halas and her colleagues at Rice University in Houston recently reported that even small amounts of nanoparticles distributed over the light-collecting face of a photodiode can significantly augment — or suppress — the photocurrent that is...Read full article
