History of IR and FTIR spectroscopy. Chemical IR spectroscopy was emerged as a science in 1800 by Sir William Herschel. Firstly most IR instrumentation was based on prism or grating monochromators. Michelson invented interferometer in 1881.
Over 100 years later, in 1941, Russell Ohl invented the solar cell, shortly after the invention of the transistor. Light (photons) striking certain compounds, in particular metals, causes the surface of the material to emit electrons. Light striking other compounds causes the material to accept electrons.
