Reflectance spectroscopy both specular and diffuse are of great value for the analysis of material's surface.

Raman spectroscopy is a tool that is widely used in solar cell industry to monitor the quality of silicon manufactured for PV cells; is an excellent tool for distinguish and quantifying crystallinity in silicon; provides direct insight into solar cell processing and prevents less efficient cells from leaving production. Spectroscopy is also used in order to test the antireflection effect in porous silicon coatings in solar cells.
