Analysing Solar Cell Material Properties with Confocal Raman Imaging

A valuable tool for obtaining detailed knowledge of the micro and nano structure of photovoltaic devices, as well as their chemical properties, is confocal Raman Imaging. It reveals optical information, the 3D distribution of chemical compounds witihn the sample, its crystallinity, and any material stresses.

This article describes the application of Confocal Raman Imaging for the analysis of stress fields around laser-drilled holes on a Si solar cell, and the investigation of concentration-dependent properties of a dye solar cell.
