Investigation was performed to one of the chalcopyrite materials, Cu(In,Al)Se2 (CIAS) to observed the Al effect on the structural properties. The investigation was done by CIAS preparation, i.e. pulsed laser deposition and selenization, and characterization, i.e. film composition and structure. The Al composition was 0%, 9%, 20%, 28%, 50%, and 67% of [Al]/[In+Al] ratio, and each Al composition had varied [Cu]/[In+Al] ratios for the detail investigation of Al effect. In the phase formation, the results show that Al hinders the CIAS chalcopyrite formation at Cu rich composition. CIAS diagram phase is close to the diagram phase of CIS system, which the more Al content in the film leads to a single phase formation of CIAS chalcopyrite. © 2019 Published under licence by IOP Publishing Ltd.
