Abstract

A camera for recording the intensity of light backscattered from textured photovoltaic samples is described. It was realized by modifying a professional folding camera, for use on optical bench. The collimated light from a laser source crosses the camera and impinges on the test sample. The light backscattered by the sample exposes a punched photographic plate on the front side of the camera. With a proper choice of the laser light wavelength, the optical effects produced by surface or subsurface features of the sample can be in this way recorded. The analysis of the light diffusing characteristics of textured photovoltaic samples can be directed towards improving their light collection capabilities.
