Photovoltaic Devices: Organic Heptamethine Salts for Photovoltaics and Detectors with Near‐Infrared Photoresponse up to 1600 nm (Advanced Optical Materials 7/2016)

A new series of organic heptamethine salts with a wavelength-selective near-infrared photoresponse as deep as 1600 nm is demonstrated by R. R. Lunt and co-workers on page 1028. This work expands the spectral window for organic molecules and can be used to enable low-cost near-infrared photodetectors, transparent photovoltaics, and multijunction solar cells.
