Anorganic nonlinear optical crystal oftris thiourea potassium chloridehas been grown by slow evaporation technique. The optical absorption study reveals that the grown TTPC crystal exhibit lower cut off wavelength at 300 nm and the minimum band tail (urbach) energy indicates the good crystalline nature of TTPC crystal.The non-linear optical (NLO) parameters are theoretically calculated by the DFT method. Non-linear optical properties were also estimated with the aid of a TTPC molecule as a model of an acceptor, and a final set of optimal systems were identified as potential candidates to be implemented as photovoltaic material. The above essential parameters manifest appropriate usage of TTPC as a nonlinear optical material.
