© 2018 American Scientific Publishers. We report the growth of copper tin telluride nanoparticles as an absorber layer using a chemical bath deposition (CBD) process for solar selective applications. The XRD results showed the phase of Cu 2 SnTe 3 with a cubical structure. The larger-sized nanoparticles resulted with increased absorption properties and the optical band gap ranging from 1.93, 1.90, 1.58 and 1.56 eV for deposition times of 20-120 min, respectively. Then, the electrical properties of Cu 2 SnTe 3 nanoparticles were also provided a higher current (6-8 mA) with bias potential of zero.
