Spectroscopy Tests for Best Organic Photovoltaics
Spectroscopy Tests for Best Organic Photovoltaics Spectroscopy may provide a way to identify materials for organic photovoltaics based on their charge formation efficiency. In a recent study of organic solar cells, researchers used photo-induced and electrochemical spectroscopy to determine the change in absorption after femtosecond excitation and charge injection.

WHITE PAPER
Andor Technology plc, Corporate Headquarters - Spatial Light Interference Microscopy Spatial Light Interference Microscopy
Andor Technology plc, Corporate Headquarters

Spatial light interference microscopy (SLIM) is a highly sensitive quantitative phase imaging method, which is capable of unprecedented structure studies in biology and beyond. SLIM combines two classical ideas in optics and microscopy: Zernike's phase contrast method, by revealing the intrinsic contrast of transparent samples, and Gabor's holography, by quantitatively retrieving the phase information. SLIM provides the spatial uniformity associated with white light methods and the stability associated with common path interferometry. In addition, due to the short coherence length of the illumination, SLIM also provides excellent optical sectioning, enabling three dimensional tomography.
