LIGHT HARVESTING SYSTEM EMPLOYING SURFACE FEATURES FOR EFFICIENT LIGHT TRAPPING

摘要

A light harvesting system employing a photoresponsive layer having a plurality of light input ports that are formed in a light input surface of the layer. Light received by the light input ports is admitted into the photoresponsive layer an incidence angle that is greater than a predetermined critical angle, such as the angle of the total internal reflection (TIR). The admitted light is retained in the photoresponsive layer and is propagated within the layer until it is substantially absorbed.

主权项

1. A light harvesting system, comprising:
a generally planar layer of photoresponsive material having a generally smooth light input surface; and a plurality of light input ports distributed over said light input surface, wherein each of said light input ports is configured to admit light into said layer at an incidence angle that is greater than a predetermined critical angle.
