The chapter briefly reviewes its today’s level of use of Fourier Transform Photocurrent Spectroscopy and more basically explaines the general principles and conditions of use. Principal advantages of F-T allow maintaining special condition of measurement such as constant photocurrent or constant illumination or allow achievement of high intensities. Method has so far been used for variety of materials: thin film silicon, nanocrystalline diamond, organic semiconductors and CIS compounds. In a laboratory FTPS can be sometimes replaced by CPM method (in most cases) or by Photothermal Deflection Spectroscopy (only non-absorbing substrates, lower sensitivity requirements) and its advantage over these methods is speed and sensitivity. Its disadvantage is wavelength dependent modulation frequency in range of kHz that requires correction procedure. Despite that FTPS method has been proven to be useful in many scientific and also one industrial application.
