Application Note: Analyzing Solar Cell Material Properties with Confocal Raman Imaging
12 November 2012

In the research and development of photovoltaic devices the primary goal is to increase the conversion efficiency of the solar cells or improve the production process. A valuable tool for these investigations is Confocal Raman Imaging, as it not only reveals optical information, but also information regarding the 3D distribution of the chemical compounds, crystallinity and material stress. This application note from WITec describes the application of Confocal Raman Imaging for the analysis of stress fields around the laser-drilled holes on a Si solar cell as well as the investigation of concentration-dependent properties of a dye solar cell.
