Cation exchange synthesis of CuIn _x Ga_1-x Se₂ nanowires and their implementation in photovoltaic devices.

ABSTRACT: CuIn _x Ga_1-x Se₂ (CIGS) nanowires were synthesized for the first time through an in situ cation exchange reaction by using CuInSe₂ (CIS) nanowires as a template material and Ga-OLA complexes as the Ga source. These CIGS nanowires maintain nearly the same morphology as CIS nanowires, and the Ga/In ratio can be controlled through adjusting the concentration of Ga-OLA complexes. The characteristics of adjustable band gap and highly effective light-absorbances have been achieved for these CIGS nanowires. The light-absorbing layer in photovoltaic devices (PVs) can be assembled by employing CIGS nanowires as a solar-energy material for enhancing the photovoltaic response. The highest power conversion efficiency of solar thin film s
