In the chemical reduction process using ethylene glycol as the solvent and NaBH4 as a reducing agent, CuIn and Cu2In phases were detected. Upon increasing the molar ratio of the reducing agent to the metal ions, Cu11In 9 and In were formed and coexisted with Cu-In alloys. The obtained nanoparticles were utilized in pastes for coating Cu(In,Ga)Se2 films. The XRD results and Raman spectra elucidated the formation mechanism. During the selenization process, InSe and Cu2-xSe were produced and then reacted with each other to yield CuInSe2. Cu(In,Ga)Se2 was also prepared using the nanoparticles via the reduction reaction. In the route developed herein not only was the temperature of the synthesis of the chalcopyrite compounds reduced to 450 ¢XC, but also the phases of the powders that were used in the synthesis of Cu(In,Ga)Se2 films were controlled. ? 2014 Springer Science+Business Media New York. |
