A Brief Overview of Phenomena Involved in Light Trapping

Abstract

Light trapping is the capturing of photons for use in applications such as solar cells, sensing, photo-electrochemistry, and thermal photovoltaics. Light enters the structures involved in these applications through refraction, scattering, or the systematic scattering provided by diffraction. The chapter examines these entry paths and the various optical processes that can be present in a light trapping structure.
