Due to containing expensive rare metals of In and Ga, CIGS chalcopyrite materials have still not been fabricated as thin film solar cells on a large scale. Fortunately, another chalcopyrite material, Cu2ZnSnS4 (CZTS) has been confirmed as a promising alternative for next generation solar cells. Except for the optical-electronic properties similar with CIGS, CZTS materials have the significant advantage of containing earth-abundant chemical elements. Actually, the conversion efficiency of solar cells made of CZTSSe have been close to 10% (2020 works). To increase this efficiency score the CZTS nanowires have been used as an absorber part for solar cells. I would like to know the simple method to fabricate this nanomaterials with high quality.
