Title: BROADBAND AND TUNABLE ORGANIC-INORGANIC HYBRID SHORT-WAVE INFRARED MATERIALS
Abstract:
The present invention relates in part to short-wave IR (SWIR) materials comprising generic mixed salts of empirical formula AaBbMcXd that are composition-dependent, broadband, and tunable. These materials have unique light absorbance wavelengths from 0.4 to 2.6 μm, including both the visible and SWIR. The preparation procedure for the SWIR materials is simple, including the use of widely available, cheap, and non-toxic precursors, unlike existing state of the art alloy SWIR materials. These novel materials have broad applications in security, surveillance, military, machine vision, photovoltaic solar cells, medical treatments, spectroscopy detector, and thermography. The present invention also relates to methods of fabricating a film comprising the composition of the invention and to photovoltaic stacks comprising the composition of the invention.
